PFMA-1 is a 150 kJ, 40 nH Mather-type plasma focus designed for repetition frequencies up to 1 Hz and dedicated to the neutron-free endogenous production of 18F. PFMA-1 utilizes 32 capacitors, 11.1 μF each, charged in parallel at 30 kV. Snowplow calculations predict a 1.5 MA peak current and a 2.5 μs quarter-period for this device. To achieve low inductance and high peak current, one spark gap and...
