Abstract
PURPOSE:To increase the gas discharge density of a radioactive gas and to enhance ionization efficiency by adding filament to the outside peripheral face of an electrode in the state of insulating the filament from the electrode and energizing the filament so that the filament generates heat. CONSTITUTION:Desired electric power is supplied between terminals 23 by a power supply to ignite the filament 20 and to generate thermions. Furthermore, max. 5kV negative DC high voltage is impressed continuously to the cylindrical electrode 5 by a 1st DC high-voltage power supply 17 and max. 1kV negative DC high voltage to a cylindrical vessel 1 by a 2nd DC high-voltage power supply 18. Gaseous Kr-85 is then ionized by the glow discharge in an ionization chamber 2 and is converted to plasma. The thermions 21 released from the filament 20 at this time contribute to an increase in the density of the glow discharge plasma 22. The ionization efficiency is thus enhanced.
