New Parts: Cathode Ray Tube, 3D Ceramic Test

18 08 2011

I bought an old oscilloscope CRT at Leeds Radio. RCA-3BP1

I will eventually break this tube (implosions! I know!) and use the electron gun and phosphor inside the vacuum chamber.

The idea is to run the sydney experiment with a pure electron beam. We are currently using an air or deuterium plasma.

Before I break the CRT I will operate it in tact. Here is the pinout for 3BP1.

This sweet CRT hack is a good start for the power supply needs.

Already got the hot cathode running:


On the 3D printing front I received the 3D printed ceramic coffee cup I ordered last month:

It looks really promising. Soon we’ll have a 3D printed ceramic magrid.
