This does not mean that I have not been busy.
have removed the high voltage accel section and door and fitted a new SS door with a low accel section --good to around 40kV
this is now setup for large area sputtering so I'm running 20kV 15mA argon ion beam onto target de jour. Just finishing some Chromium work for a customer
New door using the same ion source but on a low voltage ceramic break you can see the 3kV Zener array that provides the ion source anode / cathode potential, local small bottle of Argon and the metal clad resistors 20K total that provide the ballast to the Spellman PSU
The Clear and blue lines going to the ion source are the Kerosine cooling loop that keep the NdFeB magnets happy inside the ion source
heres the high voltage door sitting on the bench
