Rb. Baksht et al., STUDY OF THE EFFECT OF PREIONIZATION ON CURRENT SHARING BETWEEN SHEATHS OF A DOUBLE-CASCADE GAS PUFF, Plasma physics reports, 23(3), 1997, pp. 175-182
The current sharing between inner and outer gas-puff sheaths is detect
ed by direct current measurements. The conditions under which the curr
ent sharing does not occur are experimentally found. A new preionizati
on technique using a magnetron discharge in crossed E x H fields is te
sted and its high efficiency is demonstrated. This technique is compar
ed with the conventional technique using spark preionization.
