| High voltage electronic load for PMT supply testing |
| (1/1) |
| speakerguy:
Hey guys, Odd request here - I'm needing to test a high voltage power supply for a PMT detector. We design these occasionally and our test systems are usually thrown together by whatever engineer gets assigned. I'd like to just buy a load bank and write some PyVisa code to automate testing and be done with it for all eternity. Does anyone know of an electronic load that will handle 2kVDC (min) to 5kVDC (nice to have) and maybe also measure ripple and noise? I would love to not have every engineer re-think how to adequately test a new PMT supply every time we have to modify a design. Thanks for any help. |
| David Hess:
I am dubious that anybody makes a suitable electronic load. A PMT application uses a series string of high voltage resistors to create the dynode voltages. I would use that as the test load. |
| speakerguy:
Agreed, I am having trouble finding anything. We typically test them either with the intended PMT itself or with a string of resistors, but if something in this space exists it would be a nice find. |

https://www.appliedkilovolts.com/product.cfm?prod=hpz havent heard of or used this company before, but a 4 quadrant power supply seems like a good starting point. Is 400uA enough current? Edit: looking at the datasheet, it's a Harris owned company. Bring your checkbook. |
| speakerguy:
Awesome, thanks! And I'm consulting so it's their checkbook :) But yeah 400uA will cover most all use cases. Thanks again! |
