Triggered spark gap performance is key to the success of pulsed power systems, and precise gas pressure control is key to the performance of triggered spark gaps. No matter where you are, the pressure now isn’t the same as it was yesterday. Meteorologists measure atmospheric pressure because it is a sensitive indicator of weather conditions. WHIP holds absolute pressure rock-steady to optimize peak current, pulse shape and jitter while extending component lifetime.

 

WHIP converts the output of your waveform or pulse/delay generator into a precise pressure waveform and makes the actual pressure at any instant available to your oscilloscope or DAQ for real-time monitoring. If you need constant pressure regardless of environmental variations, adjust your pulse/delay generator output to 2.5 Vdc and you’ll see spark gap pressure stabilize on your oscilloscope to 25.00 psia within a fraction of a second. Or to automatically measure the self-break curve of an experimental triggered spark gap, program your AWG to output a 10 to 0 V ramp and WHIP will ramp spark gap pressure from 100 to 0 psia.

What does “absolute pressure” mean?

Most regulators control “gauge pressure.” That’s psig and it’s relative to atmospheric pressure when you’re reading the gauge. Absolute pressure is relative to vacuum and is unaffected by the weather and air currents in your lab.

Is there an SI version? 5 V signal levels?

Yes we can provide versions calibrated in kPa, bar, or any other unit your heart desires. Contact us to tell us about the customizations you want.

How much will this improve jitter?

Depends on the spark gap, trigger risetime, and operating pressure. Jitter may be reduced by 100 ns or more for a MV cascade spark gap.  One simple switch like FLASH or FLARE won’t benefit much from tight pressure control if a fast trigger is used.

 

How do I adjust the pressure?

Output pressure is proportional to the 0-10 V command voltage signal that you supply from a BNC cable.
