Electron tube filled with low-pressure helium gas, and containing a thermionic cathode, control grid, and anode. This tube is for quantitative investigations of the typical properties of a gas-immersed triode, recording the current-potential (IA-UA) characteristics of a thyratron, and observing discharges and discontinuous energy release of helium atoms during inelastic collisions with free electrons.
- Max. heater voltage: 7.5 V AC/DC
- Max. anode voltage: 500 V
- Anode current: approx. 10 mA at 200 V (anode)
