Cross-sectional side view and top view of vacuum chamber design (second to final draft; low quality picture).I haven't scanned the diagram of the side view (with the inlet ports), but it's simply some holes drilled in at the some angles for standard fitting weld-ons.
I'm waiting for the vacuum gauge controller to arrive at my doorstep. Putting it together is the first part of the construction. It's one of the most expensive parts (beside the diffusion pump, mechanical pump and electromagnet core and vacuum chamber), but I got a very good price on it from industrial surplus. I just hope it works without issues. Bigger issues now are,
- the C-frame electromagnet core/flux return bars (need to get together with the team to finalize the circuit and solenoid windings, after which I'll model the field with Poisson's equation on MATLAB)
- the high-voltage radio frequency amplifier (if you read the write-up, you'll notice that the design has a much smaller voltage gain than required; and we need >>2500V 0.1uF RF capacitors, which don't exist apparently, so we're working on a capacitor array design based on a matrix of 10nF ceramic capacitors)
- the proton source/filament thermionic heater, which is related to the hydrogen pump (I'm also planning to model the flow field numerically in 2D so that I can simplify the design and do away with a pipe leading all the way to the filament; at present, the pressure gradient with the placement of pump inlet and hydrogen pump inlet near each other is probably going to cause the hydrogen to 'short-circuit' to the vacuum rather than going past the filament)
4. the remaining work requires some "brute force effort" on the, pump pipeline arrangement, high voltage deflector/collimator, and redesigning of the inlets to accommodate the KF flange standard.
P.S.: My team mates came across a mathematical physicist at the Agency for Science, Technology and Research who said that he was very impressed with the work and offered to find funding and a supervisor for the project. Quite a lot of money is needed for a 1.4T electromagnet. Let's see how it goes.
