I recently came across todayandtomorrow, a mind blowing contemporary art blog. It made me want to paint. I painted:

Oil on masonite.

Electron Gun

12 01 2010

Yesterday I was at the lab (which is absolutely freezing, the boiler is broken). I installed the electron gun:

I fumbled the flange when I was removing it, and broke the ceramic tube. Ugg. I’ll have to make another one.

Notice the ceramic’s discoloration from the plasma of the Fusor. Why? Plasma is corrosive, but still rather surprising to see such a dramatic change.

Unfortunately, I installed this incorrectly: a centimeter of the lead wire is unprotected by ceramic. The plasma was forming around this lead.

So I’ll have to open the chamber back up and try again. I think it’s time to invest in a powered torque wrench. Doing the large conflats by hand is a real time consuming pain in the ass (and knuckles when the wrench slips).

Another useful upgrade are these plate nuts:

These are metal plates with two threaded holes, shaped to match the corresponding CF flange’s bolt hole patterns and replace the individual nuts. The plate nut’s major advantage is, once two bolts are manually started, the plate nut acts as its own backing wrench and washer—the bolts are tightened using one wrench.

My friend jewelry designer Max Steiner designed this amazing necklace based on a Fusor’s grid for a Kickstarter fundraiser I hope to launch soon:
