DISCHARGE CIRCUITS AND LOADS
EFFECT OF PULSE CABLE BETWEEN THE FAST-DISCHARGE CIRCUIT AND
A LASER LOAD
For laser loads, pulse cables create:
1. Reflection oscillations on pulse crest
2. Current increases because of cable resistive losses and radiation
;hields not perfect).
3. For load faults, cable can propagate more than 2Vo reflections
depending upon total circuit Q.
4. For fast pulses (y nanosecond risetime) skin effect degrades risetime
over Y 30 m for RG-17U.
Note that the cable looks like:
for pulse durations much longer than its two-way transit time. Then this
cable acts as a resonant circuit in conjunction with PFN and/or trans-
for' er stray C and L. This can give rise to post-discharge oscillations
that may be damaging to the switch or load. Damping shunt L-R networks
in series with the coaxial cable center conductor at both ends of the cable
generally control this.
Here’s what’s next.
