I bought a Soviet-era 'new/old stock' Cathode Ray Tube (CRT), historically intended for use in a small oscilloscope. My goal is to explore atomic diffraction (with a hack):
But as a chemist/physicist I'm not well versed in one of the critical components of those planned experiments: the High Voltage Supply (HVS, up to approx. 7,000 V).
This being a 'backyard science' project budget is of course important.
Window shopping for something suitable showed up a rather bewildering array of different possibilities with a wide price range and for the second hand options often very poorly written technical specifications.
So far I'm gravitating somewhat towards this ebay listing. To avoid linkrot I'll summarise its advertised characteristics, below.
Very high voltage regulated power supply module.
This module allows, from a power source of 8 and 12V, to obtain an output voltage of 300 to 10,000V adjustable by a potentiometer.
The available power is around ten watts, ie 1mA at 10,000V or 10mA at 1000V.
An output is provided for the connection of a voltmeter for displaying the output voltage with 1V = 1000V.
The card is delivered wired and tested, accompanied by its user manual, connection plan, diagram and description, ready for use.
But I'm not at all certain of its suitability. From the description and bearing in mind my awful ignorance on HVSs I'm not even sure the advertised voltage is AC or DC!
