Fusor Construction and Start
Posted: Tue Jul 26, 2016 6:32 pm
Over the past two years I have been collecting parts for my fusor. Due to other interests and work I have not really had time to build. However, I have decided to start up again. Here are the parts collected over the past years...
The first image is my diffusion pump. It came out of an Alcatel ASM-10 helium leak detector. It has an ISO 80 inlet flange and an NW 20 outlet flange. The pump should require a 6cfm vacuum pump and at least a pressure of 50 microns for it to start.
The next picture is my vacuum pump. Its a 2 stage, 4 cfm pump with an ultimate vacuum of 3 microns. I will take off the flare fittings then replace it with an NW 25 flange and hose.
ISO-80 to 2.75" conflat adapter and o-ring.
The main chamber consists of a conflat 6 way cross attached to a 3 way. The 3 way cross adds extra ports, allowing the gas to be injected further away from the pump and grid.
The bellows and gate valves will allow throttling of the chamber. The butterfly valve will just be used to isolate the chamber from the pumps.
The up to air valve and a Mastercool thermocouple gauge.
30kV feedthrough.
The gas system will contain of a CO2/Argon regulator with a 5 micron copper orifice.
