The discussion revolves around measuring the voltage of a Cockcroft-Walton multiplier over time to observe its charging behavior. Participants explore methods for capturing transient waveforms and the implications of using oscilloscopes in this context.
Participants express differing views on the effectiveness of their measurement techniques and the conditions under which accurate observations can be made. The discussion remains unresolved regarding the best approach to measure the charging behavior.
There are limitations regarding the assumptions about the driving frequency and the grounding of the measurement setup, which may affect the observations being discussed.
Well, it's a transient, so unless you have a storage CRO or a synchronised camera, you won't see it.shrinky said:Yeah. Ideally I'd like to see the oscillation with amplitude offset increasing as time goes on.
Are you saying it's not working?Right now I have a simple half wave multi stage multiplier set up. I can measure the rectification part, so the sine wave only goes to the positive and not negative, but I don't see the amplitude increase so that the dc offset is always zero essentially.
It shouldn't matter.It could be my driving frequency isn't correct perhaps?
Unless your driving source is floating, you can't connect the CRO across any ungrounded element.Rhetorical I guess but is it better to measure the voltage across the capacitor at the highest stage or measure the potential relative to ground.
