Rackmount trigger generator, high PRF

The APELC high-PRF trigger generator unit utilizes a pulse forming circuit to provide the trigger pulse to a Marx generator.  The trigger generator can provide a 18-kV trigger pulse at up to 1 kHz pulse repetition frequency (PRF). The trigger unit provides LED indicators on the front panel for notification of trigger-circuit HVPS conditions .  The diagnostics, Thyratron HVPS Analog Out, Marx Analog Out (V), Marx Current out, and Marx V peak are available on the front panel of the trigger unit.  These signals can be monitored on any 1- MΩ oscilloscope channel or handheld DVM by connecting to the BNC jacks on the front panel shown below.

Pulse characteristics of the pulse circuit inside the APELC trigger generator include 30-ns risetime, and 18-kV peak voltage. The front panel shown above includes: (A) fiber optic ST connections and input selector knob, (B) thyratron HVPS status indicators, (C) thyratron heater switch, (D) HVPS power switch, (E) thyratron voltage and Marx charge current and voltage diagnostics. Timing input may be provided by a delay generator (820 nm) or by an optional APELC fiber-optic handheld remote control.
