NUDT Spheromak Plasma Ring
Most detailed public description of a Chinese military spheromak plasma ring system with explicit space warfare applications.
01 Definition
02 Detailed_Analysis
NUDT's coaxial gun system (1.2 m electrodes, 20 kV, 350 μF) generates spheromak plasma rings at ~1,000 km/s with 10^16 cm^-3 electron density, 1 MJ/m² energy density, and ~1 T toroidal/poloidal magnetic fields. Stated applications: de-spinning/reclaiming satellites, rendezvous/docking, spacecraft formation. Clear dual-use ASAT potential. 2007 USCC report identified 'Plasma Attack against Low-Orbit Spy Satellites' as Chinese ASAT concept.

04 Deep_Dive_Intelligence
NUDT's 2024 paper (Zhao, Zhang, Yang, Huang, Ma — Systems Engineering and Electronics, Vol. 46, Issue 1, pp. 261-270, DOI: 10.12305/j.issn.1001-506X.2024.01.30) describes a coaxial gun system with 1.2 m electrode length, 20 kV voltage, 350 μF capacitance, generating spheromak plasma rings at ~1,000 km/s with 10^16 cm^-3 electron density, 1 MJ/m² energy density, and ~1 T toroidal/poloidal magnetic fields. The application is 'remote magnetic control of space targets' including de-spinning/reclaiming satellites, rendezvous/docking, and spacecraft formation. A 2007 USCC report identified 'Plasma Attack against Low-Orbit Spy Satellites' as a Chinese ASAT concept. Follow-up publications include a 2025 electromagnetic de-tumbling review, a 2023 particle beam space transmission paper, and 2025 plasma cloud propagation and generation studies. The 2025 generation study achieved 620 km/s emission velocity with 25 kV initial voltage. NUDT is a military university directly under the PLA.
