After the final exams and some unexpected health issues, I'm finally able to continue working. I just got the inverters for a power supply like that demonstrated by Nathan Marshall, but before that I'm (again) revising the HV supply. More specifically, I've found a way to use the blocking oscillator...

I can only speak from my experiences in the Spanish education system, but if the American is anything like mine, I would be very surprised to see an University encourage a program with "nuclear" in the name

Nathan: Thanks for the data. Hopefully once finals are over and the components arrive I will get to do some work. With regards to the video, a great and clear presentation. I didn't know you were behind Gooferking Science! I remember around 4 years ago seeing your Electron Acceleraton in a Wine bott...

It was not my intention to derail this thread, and as you say a new one should be started.
I thought it was acceptable, since I only wanted to know the operating frequency (since I can calculate all the other things I need from it),but I suppose I will just have to find out.

This is the definitive book on electrical conduction on gases and related phenomena, such as recombination or the mobility of ions. Published in 1961, it is the modern equivalent to the previous "bible" on the subject by the same author, Fundamental Processes of Electrical Discharges in Gases , publ...

John:
I plan on buying 20kV 20mA diodes, with a trr of 100ns.
The capacitors are what worries me most, because everything else I've found with similar capacity and voltage ratings breaks the bank in my birthday fund.

Nathan: First of all, I want to express my gratitude for all the details provided about a superb build, especially the affordable power supply. I myself intent to imitate your efforts using a transformer I have found from a tube based CRT TV. The only problem are the capacitors themselves. The only ...

John: I think we are talking about different things. You probably reference something like this: https://www.mouser.es/ProductDetail/JKL-Components/BXA-24529?qs=sGAEpiMZZMvlvmHaYoGmZdvKIw2%2F%252BoHV5yU7qjc3YDs%3D . Which I have read about in Doug post "Standard HV Supply for detectors". I was talki...

John: That seems way too high. Taking the output directly the output at the transformer (thus avoiding any losses in the multiplier) we get a power 1.5 W (the 75V claimed times the *optimistic* 20mA). At 400V that is around 4 mA, which is respectable. Still, the noise is what worries me the most... ...

Hi: I was aware of the mosquitoe killing HV source. It is a "Joule Thief" like the one I previously discussed (i.e a blocking oscillator) with added voltage multiplication at the output. Thus, it's noise makes it unsuitable to my needs. What is the noise in the commercial module you described before...
