Krytron firing

Krytron Tube (6/24/2017)

Voltage waveforms were measured with a tektronix TDS3034B oscilloscope and P6015A high voltage probes. The krytron was connected to a 20nF 2kv capacitor charged through a 1M resistor, the keep alive was connected through a 25M resistor, the trigger was capacitively coupled to the trigger transformer from an SSY-1 laser and connected to the anode with a 100k resistor, and the load was a 1ohm resistor.

the tube achieves ~200ns delay time(typical of the kn6) and almost no jitter, there is some ringing due to stray inductance in the circuit.
