| Popis: | The energy distribution function of the electron beam produced in a transient hollow cathode discharge is measured using a method which is based on the collector self-biasing, allowing an access very close to the extraction hole. The distribution obtained is a mainly polyenergetic one extending over a range of up to some tenths of kiloelectronvolts. It is composed both of runaway electrons, whose energies we assume are equal to the instant discharge voltage, and a main part composed of a monotonically decreasing energy distribution. The ratio between these two populations is around 10% and strongly increases with distance from the extraction hole. |
