Abstract: 1,028,834. Recording tracks of particles. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 2, 1964 [June 11, 1963], No. 22816/64. Heading G6P. In a device for indicating the distribution of a radio-active emitter over a given surface, a spark is formed at each point where radiation is incident on the indicator. The device consists of a vessel containing a low-pressure gas and a D.C. energized cathode and anode. A radiation particle enters the vessel, passing through the cathode, and causes electron multiplication in the gas. The D.C. voltage is so chosen that no spark is formed at this stage. An external circuit detects the electron pulse at the anode and causes an impulsive negative potential to be applied to the cathode, thus forming a spark at the point of impact of the radiation on the cathode. The metal cathode may be replaced by a scintillator and a photocathode.
