Transformers for evaporation and glow discharge.

Jongmin Jeon All Messages By This Member #72 Hi, friends I'm starting to build the Vacuum deposition system just with a CVC diffusion pump and a Edwards pump. Right now , I'm looking for transformers for evaporation and glow discharge, but Actually I was studing bilody included with insects such as butterflys, and so I don't have any knowledge related with electrical power. Could you tell me which transformer is better or the range of output current, voltage or watt for evaportion and glow discharge ? If I can take care of these troubles, Next problem is to find or make electron beam gun power supply. To find it, I am still watching ebay'power supplys everyday. Anyway It is not easy. Good luck everybody,~~!! Jeon ^,^
[email protected] #73 Maybe your best bet would be to purchase a small 110 Volt arc welding unit. They have variable outputs and will certainly zap any material you might want to coat. Although the manufactures don't recommend this... using the on and off switch will provide the control needed to get started. The output of most machines is 50 to 100 volts and 50 to 150 amps... this will do for most needs. I too am putting a small coating unit together and having the same problems. Let me know of your progress and I will do the same. Bill Lang, Stockton , CA

I use a welder to heat the evaporation tungsten I bought .060 welding electrode tungsten and it seems to be to large so I need a lot of amperage to get it hot I've read of other guys using a large battery charger for the power source and they regulate the 110v side of the charger with a dimmer switch. I'll try to find the web site for you. E-Beam now that's ambitious—I have been studying this and not having a lot of luck in finding the voltage / amperage and coil specs needed. Sputtering system may be easier to deal with again finding the source for a high voltage and high amperage source may be difficult (expensive)Fabricating a Sputtering head seems to be easier than E-beam. Good Luck Keep us posted Ron VacuumX@..., "jongmin686" <jongmin686@y...> wrote: Hi, friends Hi> I'm starting to build the Vacuum deposition system just with a CVC
