Unit Size each
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. Specifications Max. heater voltage: 7.5 V AC/DC Max. anode voltage: 500 V Anode current: approx. 10 mA at 200 V (anode)
