Abstract :
The length of insulator sleeve is varied to investigate its effect on the pinch formation in the plasma focus facility. In this paper, the effect of insulator length on the time to pinch at various pressures and working voltages
in the 1.15 kJ Mather type plasma focus is investigated.
The results show that with 4.5 cm insulator length the time
to pinch at all pressures is minimum. Other results also
confirm that with increasing of pressure the time to pinch is
increased. Moreover, with increasing working voltage the
time to pinch is decreased. Pictures, captured using a digital
single lens reflex (DSLR) Canon EOS 7D system, show
that multipinch phenomenon is formed.
