Abstract : The breakdown of a gas in an electrodeless discharge is studied. The configuration consists of a long cylindrical gas column subjected to a strong, fast rising axial magnetic field. The investigation showed that when losses are by free electron diffusion and electric fields due to charge separation are negligible, appreciable multiplication of electrons takes place in an interval of time 2tc (the cut-off time for ionization) when the magnetic field is nearly zero. The voltage around the discharge tube that produces a given multiplication of electrons in the time interval 2tc (the cut-off time for ionization) is determined. This voltage is compared with experimentally observed breakdown voltages in argon and hydrogen. (Author)
