The lamp also comprises a testpiece arranged at the cathode end of the chamber body and an anode housed in the chamber body. The testpiece is preferably maintained at a zero potential and the anode housed in the chamber body and having a through passage is preferably maintained at a high voltage. The lamp is also provided with a closure piece at the end of the chamber body designed, if desired, as an observation window, whereby at least one window opening (18) is arranged lateraly in the chamber body (4), at about the height of the negative glow light, and a sealing closure for the inner gas space at the cathode end is provided by the testpiece (2).</p> |
