Spheromak Experiment (SPHEX)

Intelligence Summary: SPHEX

Node Identity: SPHEX is a entity categorized under "Spherical Tokamak" in the uk intelligence graph. UK spheromak device at universities (Imperial/York), demonstrated steady-state current drive via helicity injection.

Research Evidence: The following findings from 2 research documents reference this entity:

1. UK Spheromak/Compact Toroid Heritage: The UK has a significant historical research program in compact toroid concepts: - SPHEX Spheromak: Operated at UK universities (primarily Imperial College/York), SPHEX was a spheromak device using a magnetized Marshall gun for plasma formation and sustainment via helicity injection.
2. SPHEX research contributed to understanding of spheromak sustainment physics.
3. The SPHEX group developed an understanding of the dynamo in sustained spheromaks" (https://www.osti.gov/biblio/304511) - IOPscience (RFP UK): "The foundations of present-day RFP research are to be found in the early results from ZETA in 1967...
4. HICD has successfully formed and sustained current in the CTX [Jarboe (1983)] and SPHEX [Browning (1992)] spheromaks and in the CDX [Ono (1987)], CCT [Darrow (1990], and HIT [Nelson (1994)] tokamaks.

Strategic Relevance: SPHEX is a tracked entity within the uk network. With 1 documented connection to other entities, this node plays a supporting role in the network topology.

Network Linkage: This entity maintains 1 documented connections in the intelligence network: SPHEX located at Culham/CCFE.
