Compression of ultrahigh magnetic fields in a gas-puff Z pinch

Evidence is presented that an axial magnetic field of 100 kG has been compressed to 42 MG by an imploding neon gas‐puff Z pinch on a 800 kJ, 7.5 MA, 60 nsec pulsed power generator. Machine electrical diagnostics and x‐ray pinhole photographs indicate that this 420‐fold field compression was produced by imploding plasma at high magnetic Reynolds number.
