Two applications of the three-electrode neon tube are described. The first shows how the neon tube can be used for the registration of alpha rays. One electrode of an ionization chamber is connected to the grid of the neon tube and the tube flashes on the entrance of each alpha ray.
In the second device, the tube is arranged to flash periodically and it is found that under certain critical conditions, a bias potential of a volt or two has a marked and easily measurable effect on the periodicity of discharge.
