here is a picture of what it looks like so far. The bottom section houses the quartz tube with both electrodes inside of it. also the photon source is in the bottom section where it will shine through the quartz tube and through the slit cut in the outer electrode. The top part is where the electron extraction grid is. I will show everything apart once I finish the electrodes. The gauge on top is for a car with a forced induction. It shows both pressure and vacuum. I wont be putting it under pressure but I have a compressor I took of a fridge to create a vacuum.
ps. thanks everyone for the helpful ideas
