Some of these tubes contain small quantities of Cesium-137, Cobalt-60, Radium-226, Krypton-85. The radioactive elements have been added to increase the electronic response by improving the internal ionization processes.
How to build a socket for a big Russian hydrogen Thyratron tube using copper connectors made out of a pipe.
A hydrogen thyratron is a device capable of switching big amounts of energy. The major advantage over other thyratrons is that the deionization time is reduced by using the hydrogen gas, generated in a small reservoir inside the tube, from a metallic Hydride.
A vacuum tube tesla coil built around the Russian tetrode GI-30. My first VTTC and my first vacuum tube circuit, and some very rewarding results.
