Abstract
The r e s u l t s conclusion t h a t , of the e l e c t r i c a l parameters leads t o the the pinch was observed t o occur a t a l l pressures o f hydrogen i n the range 0.05-4 t o r r , while i n the case of argon it was observed only a t 0.05 t o r r pressure. These observations come from t h e voltage probe s i g n a l , which i n d i c a t e the occurrence of a sharp peak accompanied w i t h a f a s t DROP i n the voltage i n a small f r a c t i o n of psec a t these pressures. The minimum pinch time t was calculated from the rn voltage probe s i g n a l and i t was found t o be ranged from 1 psec upto 2.5 i.iSeC. The minimum pinch radius r a t i o K was found t o m be ranged from 0.45 down t o 0.3 and it decreases by increasing the hydrogen pressure. The d i f f e r e n c e on the values of K :n r e s u l t i n g from the occurrence of the minimum pinch a t d i f f e - r e n t values of the plasma current, whereas the corresponding B. and the magnetic force have a d i f f e r e n t values, tj It was found t h a t , the energy transmitted t o the plasma a t higher pressures were approximately equal and greater than t h a t t r a n s m i t t e d i n the lower pressures. Also, the average sheath v e l o c i t y was found t o be decreased by i n c r e a s i n g t h e gas pressure. The l a r g e value of t h e s t r a y inductance L o f the system 13 w i t h respect t o the average plasma inductance L was a f f e c t e d C. on the plasma current such t h a t , the peak value o f the discharge current was slightly dependent upon the type and pressure o f the used gas. Also, no change was appeared i n the current s i g n a l when the pinch occurred.
