Archived - Fusor Update - Plasma!

[Aidan Cookson]

Hi everyone, tonight I finally finished setting up my power supply and putting everything together. I was a little worried about the transformer because it was finicky last time I tried to measure voltage from it (The voltage jumped sporadically), but when I added a load, it stabilized nicely. Here are some pics of my first plasma at various voltages:

About 4.2 KV at 1.05 x 10^-1 torr

About 6.3 KV at 9.5 x 10^-2 torr

I have no idea if the colors are correct because I was using a webcam and the plasma may have been too bright for it. I will take it off tomorrow and see the colors for myself. I am also contemplating a strange issue in my voltage divider where it says the voltage is much higher than possible, yet the resistors read correctly.

Nice images of your first plasma efforts! I have placed you in the Plasma Club. All the best on any future efforts at fusion.

Thanks! I look forward to continuing my project until I have finished a real fusor.
