Does there exist any ready-made or semi-ready-made device that acts as a controller and power supply for thermionic emission filaments?
I'm thinking of something that would have a filament driver, maybe constant current, and the ability to control and measure emission current -- combined with a plentiful amount of isolation.
Filament Controller
Re: Filament Controller
An electron gun or ion source controller is what you want. Kimble Physics made/makes a series of models. There are almost always some on eBay (where I bought mine). If you can do electronic repair, there are usually some listings for “parts only” units at good prices. As with most things on eBay, try making a lower offer.

It exists, Ben Krasnow does a reverse engineering of one of those in this video:

But most power supply I see have it integrated, like mine from a x-ray machine:

The filament control is in the right side of the PCB with the red toroid core (the filament is at HV).
You will want AC on the filament, Spellman HV has a very nice pdf that cover this (page 37).
