Plasma Science and Engineering: Intellectually Diverse Field

• Plasma Science and Engineering (PSE) is the investigation of fundamental processes of ionized matter and translation to technologies. • PSE is of the most intellectually diverse sciences. • > 10^10 range in pressure (energy density) • > 10^10 range in spatial scale. • Micron-sized cathode-spot plasmas that sputter metals to place thin metal films to the plasma jets that emanate from galaxies. • Plasmas with temperatures exceeding that of the center of the Sun to plasmas gentle enough to touch human tissue for biomedical therapies.

PSE: United by Science Challenges

Despite vastly different scales and applications, common themes and scientific challenges bring cohesiveness to the PSE field.

• Complexity arising from multiple scales and phenomena. • Controlling synergistic exchanges in plasma-surface interactions. • Understanding and leveraging how complex phenomena can self-organize into coherent structures. • Controlling the flow of power through plasmas as means of energy and chemical conversion. • Developing ever more capable diagnostics, theories, and computations to characterize this complexity.

Mastering PSE Intellectually Diversity: Science Advances and Societal Benefit

Mastering the intellectual diversity of PSE advances the science frontiers and, if properly stewarded, brings societal benefit through translational research.

Enabled by PSE Today: • The internet, jet turbines, medical implants, lighting, solar cells, nanomaterials, and spacecraft exploring our solar system. • Stockpile stewardship, hypersonic flight, understanding space weather. • Magnetic fields throughout the universe to creation of states of matter that exist only in the center of stars. • Exploring whether life can exist on exoplanets.

Enabled by PSE Tomorrow: • Nearly unlimited carbon-free electricity • Compact particle accelerators for imaging and cancer treatment; • New materials, green chemical production, new modalities for medicine and agriculture, • Secure management of our Nation’s most strategic weaponry. • Fundamental knowledge of the creation of the solar system and worlds beyond.

Statement of Task (Part 1)

As part of the Physics 2020 decadal assessment, NASEM will conduct a study of the past progress and future promise of plasma science and technology and provide recommendations to balance the objectives of the field.

• Engage stakeholders on the major achievements and challenges of the past decade and the most promising areas of plasma research for the next ten years, and how plasma research impacts and is impacted by adjacent areas of S&T. • Assess the progress and achievements of plasma science over the past decade. • Identify the major scientific questions and new opportunities that define plasma science as a discipline, noting connections to and influence on other disciplines. • Discuss the nature and importance of the U.S. in multi-national plasma research activities. • Assess the scope of international research and the standing of U.S. activities. • Discuss how plasma science has and will likely contribute to U.S. national needs both in and beyond plasma science, including workforce, economics, defense.

Statement of Task (Part 2)

• Assess whether present plasma science workforce and training opportunities are commensurate with future workforce needs. • Assess the role of, and future opportunities for, universities within large national programs organized around major research instruments or community assets. • Assess whether the structure, program balance, and level of the current U.S. research effort in plasma science (federal and private) are best positioned to realize the science opportunities.

The Committee’s recommendations should not alter recommendations from the Decadal Strategy for Solar and Space Physics, the mid-decadal assessment of that report, or the Strategic Plan for U.S. Burning Plasma Research.

Organization of the Plasma 2020 Report

• Report emphasizes cross cutting themes, opportunities for collaborations, cross-agency initiatives in Plasma Science and Engineering (PSE) • High level Findings and Recommendations • F&R in chapters addressing sub-areas.

Report Outline: I. Introduction, Overview • High level status of field • Grand Challenges of PSE • Diversity, Equity, Inclusion • Collaborative Opportunities • High level Findings and Recommendations II. Basic Plasma Physics and Computations III. Laser Plasma Interactions IV. High Energy Density Physics and Inertial Confinement Fusion V. Low Temperature Plasmas VI. Magnetically Confined Fusion VII. Space and Astrophysical Plasmas.

Guiding Principles: Grand Challenges in Plasma Science & Engineering (Part 1)

• Understanding the behavior of plasmas under extreme conditions will enable energy conversion by plasmas to be predicted and controlled, to address sustainability, economic competitiveness, and national security, and expand our knowledge of the most fundamental processes in the universe.

• Mastering the interactions of the world’s most powerful lasers and particle beams with plasmas will enable precision x-ray imaging for medical science, advances in national security, compact particle accelerators, materials and sustainable energy, and open new regimes for high energy and quantum physics.

Guiding Principles: Grand Challenges in Plasma Science & Engineering (Part 2)

• Accelerate the development of fusion generated electricity, tapping the virtually unlimited fuel in sea-water, to bring carbon-neutral power to society, through economical, deployable, and sustainable fusion systems enabled by advances in experimental and computational plasma physics.

• Demonstrate that lasers and pulsed-power devices can produce inertially confined fusion ignition by producing plasma-based extreme states of matter to support stockpile stewardship, further the goal of sustainable energy, and expand our understanding of high energy-density physics.

Guiding Principles: Grand Challenges in Plasma Science & Engineering (Part 3)

• Enable electrification of the chemical industry by controlling the flow of power through low temperature plasmas to produce predictable chemical transformations in gases, on solids, and in liquids, on scales capable of economically establishing a future based on renewable and sustainable electricity (FBRE).

• Develop the capability for timely and actionable space-weather observations. With life, technology, and space travel at risk from damaging solar plasma storms, predictions of extreme events will enable mitigation of their potential effects on spacecraft, humans and power grids.

Diversity, Equity and Inclusion (DEI) in PSE

• Lack of diversity in core areas of PSE – does not reflect society it serves. Persistent problem of underrepresentation should be a high priority in the PSE community. • Must increase participation of women, ethnic and religious minorities, gender-preference and gender-identity minorities including members of the LGBTQ+ community, and persons with disabilities, recognizing this list may not be fully inclusive of all underrepresented communities in PSE. • Start at home: Assess DEI practices and engage in DEI activities at primary levels in our own organizations. • Opportunity to improve diversity in PSE with looming significant turnover in workforce. • Professional societies, universities, national academies, national laboratories, and Federal agencies now actively addressing DEI. • The Committee strongly endorses the importance of and efforts of PSE to diversify.

Findings and Recommendations (Presented in Abbreviated Form)

FINDINGS AND RECOMMENDATIONS (presented in abbreviated form)

Stewardship – Advancing Interdisciplinary Research (1)

• Finding: Plasma science and engineering (PSE) is inherently an interdisciplinary field of research. While the underlying science has common intellectual threads, the community is organized into sometimes isolated sub-disciplines. • Finding: Interagency (and inter-program) initiatives would fully exploit the interdisciplinary and multidisciplinary potential PSE in both fundamental and translational research if properly stewarded • Recommendation: Federal agencies directly supporting PSE and those (potentially) benefiting from PSE should better coordinate their activities extending into offices within larger federal agencies. • Recommendation: Federal agencies and programs focused on fundamental plasma research, and those focused on science and technologies that utilize plasmas, should jointly coordinate and support initiatives with new funding opportunities.

Examples of Potential Interagency Collaborations

• A full list of examples of collaborations with explanations is in Chapter 1.

Stewardship – Advancing Interdisciplinary Research (2)

• Finding: The potential is enormous for PSE to contribute to one of society’s greatest challenges—sustainability extending from fusion-based, carbon-free electrical power to electrification of the chemical industry. • Finding: The translational nature of fundamental research in PSE needs greater recognition at NSF. • Recommendation: The NSF Engineering Directorate (EngD) should consistently list PSE in descriptions of its relevant programs and participate in the NSF/DOE Plasma Partnership. • Recommendation: More strategically, NSF should establish a plasma-focused program in EngD broadly advancing engineering priorities – energy, environment, chemical transformation, manufacturing, electronics and quantum systems.

Stewardship – Advancing Translational Research

• Finding: With few U.S. governmental programs designed to translate industrially relevant fundamental science to practice, U.S. industries are at a competitive disadvantage internationally. • Recommendation: Federal agencies focused on plasma research should develop new models that support the translation of fundamental research to industry. Programs supporting vital industries depending on PSE should be developed through relevant interagency collaborations.

Plasma Science and Engineering Community (Workforce & Faculty)

• Finding: The multidisciplinary approach of PSE has been at the heart of its success of PSE, while working against its long-term viability in academia. • Finding: Lack of a critical mass of faculty in PSE will lead to an erosion of U.S. capability in PSE. University leadership in PSE is rapidly aging and will need renewal in the coming decade. • Recommendation: Federal agencies (DOE, NSF, NASA, DoD) should structure funding programs to provide leadership opportunities to university researchers in PSE and to directly stimulate the hiring of university faculty.

Plasma Science and Engineering Community (Education & Training)

• Finding: Plasma-specific educational and research programs that also provide opportunities to diverse and less advantaged populations are needed to ensure a critically populated PSE workforce. • Finding: PSE intern programs and summer schools are needed for undergraduate and graduate students, as are programs for students with incomplete preparation to progress in plasma physics. • Finding: Multi-agency investment in PSE education by directly supporting undergraduate and graduate students is critical. The more “duplication” of effort in these areas can only further strengthen PSE. • Recommendation: Funding agencies (e.g., NSF, DOE, NASA, DoD) should structure funding to support undergraduate and graduate educational, training, and research opportunities—including faculty—and encourage and enable access to plasmas physics for diverse populations

The Research Enterprise in PSE (Facilities)

• Finding: Given impressive investments by other nations, incremental progress in US facilities is insufficient to maintain leadership. • Finding: A spectrum of facility scales is required by the sub-fields of PSE to address their science challenges and translational research. • Finding: Mid-scale facilities (e.g., $1 mi l l i o n t o$ 40 million) offer particularly good opportunities for broadening participation within academia. • Recommendation: Federal agencies (e.g., NSF, DOE, NASA, DoD) should support a spectrum of facility scales that reflect the requirements for addressing a wide range of problems at the frontiers of PSE.

The Research Enterprise in PSE (Operations & Support)

• Finding: Investment in PSE facilities without the concurrent support of research and operations is not optimum. • Recommendation: Federal agencies (e.g., DOE, NSF, NASA, DoD) should provide recurring and increased support for the continued development, upgrading, and operations of experimental facilities at a spectrum of scales, and for fundamental and translational PSE research using those facilities.

The Research Enterprise in PSE (CPSE)

• Finding: Computational Plasma Science and Engineering (CPSE) has become essential across PSE for experiment and mission design and diagnosis, idea exploration, probing of fundamental plasma physics processes, and prediction. • Recommendation: Federal agencies should: • Support development of computational algorithms for PSE for the heterogeneous computing platforms of today and upcoming platforms (e.g., quantum computers), and • Encourage development of mechanisms to make advanced computations, physics-based algorithms, machine learning, and artificial intelligence broadly accessible.

Better Serving the Community

• Finding: Although most of the DOE-FES budget is for fusion science, the present office title does not accurately reflect its broader mission. • Finding: The national interest would be better served by renaming DOE-FES to better reflect its broader mission, maximize its ability to collaborate with other agencies and to garner non-fusion plasma support. • Recommendation: DOE Office of Fusion Energy Science should be renamed to more accurately reflect its broader mission, and so maximize its ability to collaborate with other agencies and to garner non-fusion plasma support. A possible title is Office of Fusion Energy and Plasma Sciences.

Findings and Recommendations: Take-Aways (Stewardship & Workforce)

Stewardship: Finding: PSE is extraordinarily multi-disciplinary both fundamentally (underlies much of basic physics) and now stretching into biology (epidemiology), information science, quantum, materials, with extraordinary translational value. (See Grand Challenges.) Opportunity: Broaden interagency structures to support PSE, especially translationally. Structures needed to facilitate cross-talk and funding needed to drive cross-agency collaborations. Aligns with proposed NSF reorganization - Endless Frontiers Act (S. 3832).

Education, Workforce, Diversity: Finding: Aging PSE workforce, particularly faculty, needs renewal. Next decade brings great opportunity to remake a diverse workforce, rooted in both basic and translational science. Guidance to avoid “duplication” in workforce areas has been a negative. Opportunity: Agencies need to promote programs to hire new faculty, and provide PSE specific fellowship programs for undergraduates to fill a diverse pipeline and to graduate students to fill positions in academics, national laboratories and industry.

Findings and Recommendations: Take-Aways (Research Enterprise & Community)

Research Enterprise and International Competitiveness: Finding: US is losing its preeminent position in PSE because of i) incremental progress in new and updated facilities (especially mid-scale), ii) lack of concurrent research and operational support to the facilities, and iii) to limited computational (theory, algorithms, codes) capacity. Opportunities: Support funding for a spectrum of facilities, particularly at universities, and for expanding fundamentals of PSE computations and expanding access.

Finding and Opportunity: Industries reliant on PSE (e.g., microelectronics) are at a competitive international disadvantage due to lack of Federally funded translational research. Support new modes of translational research.

Better Serving PSE Community: Finding and Opportunity: DOE Office of Fusion Energy Science should be renamed to more accurately reflect its broader mission and support interagency collaborations, e.g., Office of Fusion Energy and Plasma Sciences.
