Vacuum Chamber

September 9, 2013 at 8:45 pm

The vacuum chamber (approximate cost €400-1000) of the Fusor is where fusion takes place.  The chamber must be made of grade 306 stainless steel or higher. Between 100mm and 300mm is a good diameter for the chamber with between 150 mm and 200 mm being optimum, the chamber does not have to be spherical, a cylinder, cross or other shape work just as well but a spherical or cylindrical chamber is easier to use.  The chamber needs to have at least 5 ports.  One for the gas line, one for the high voltage feed-through, one for the vacuum line, one for a viewing port and one to use for pressure gauges.  The chamber also needs to be made from two stainless steel hemispheres to allow easy access inside, these can be welded together with two conflat rings. For a proper chamber, a 200mm diameter chamber of two 316 stainless steel hemispheres with at least five ports is the best option.
