Every fusor and fusion system seems to need a vacuum. This area is for detailed discussion of vacuum systems, materials, gauging, etc. related to fusor or fusion research.
The small Edwards diff pump in the picture below was picked up on Ebay for ~$200.00, it pumps down fast in about three minutes to below 10-5 torr and would be a good pump to consider as Fusor chamber high-vac pump.
OK Nikelopez. "B" but most applies to the "A" unless you are planning a full rebuild.
