IMPROVEMENTS IN OR RELATING TO IONISATION CHAMBER CIRCUITS

Patent ·
OSTI ID:4791884
A radiation measuring apparatus is designed which uses an a-c polarizing potential on the ionization chamber. The apparatus comprises, besides the ionization chamber and a source for the a-c polarizing potential, an a-c amplifier for measuring the chamber current, phase-sensitive means for using the in-phase or anti-phase component of the amplifier output as a measure of the radiation flux, and phasesensitive means for using the quadrature component of the amplifier output to check that the apparatus is functioning properly.
