Fusor cleaning time!

Post by Tman » Sat Aug 19, 2006 5:59 pm

I am getting ready to give everything an acetone cleaning. Then I'll flush my recently aquired 3" diffusion pump with some 91% isopropyl, and heat it a while to evaporate any water.

After cleaning I just have to wait for the bubble detectors I ordered to arrive. I dont want to bother injecting D2 unless I have at least one neutron detector around.
My He3 detector is getting close.

Good luck on cleansing your system. It is a good idea to start fusion experiments in a clean atmosphere, no matter how reduced that atmosphere is.

Acetone is very volatile, but it is a good idea after the liquid solvent has evaporated, to apply a heat gun (or a hair dryer) to each part until it is to hot to hold in your (gloved) hand. This will dramatically shorten the initial pumpdown, and help keep your pump oils (assuming a mechanical roughing pump and diffusion pump) clean.

A healthy amount of gas ballast in the roughing pump for the first half hr is also a good idea.

System parts look good. You are ready to begin.
