Book came in



Hi All,
    The book Physics of Pulsed breakdown in Gases by Korolev and Mesyats
came in the mail, finally.  A quick overview indicates that most of the
cases are for around atmospheric pressure discharges.  On page 123 there is
a calculation of when the voltage across a volume discharge, of 1 cubic
centimeter and 1 centimeter in length, starts to drop.  They calculate 1
kOhm.  Interesting number?  On page 73 is a graph of the result of a
simulation verified by experiments.  The graph is for a current limited
voltage source of 20 kV across a 2 centimeter gap in 500 torr nitrogen.
The current limiting resistance  was 485 ohms and the interelectrode
capacitance was 28 pF.     The graph indicates that the current in the gap
didn't reach 1 Ampere until a time of 30 us had passed.  This was when the
voltage across the gap started to fall!
