Abstract
1,180,259. Measuring ionisation chamber charge. COMMISSARIAT A L'ENERGIE ATOMIQUE Dec.13, 1967 [Dec.13, 1966], No.56632/67. Headings G1A and G1U. The total charge produced in an ionisation chamber in response to a pulse of radiation is measured by transferring a substantial predetermined portion of the charge to a low-leakage capacitor and subsequently discharging the capacitor through a high resistance. The capacitor voltage is fed through a high impedance input e. g. an electrometer tube or a field effect transistor to a trigger circuit which produces a pulse when the capacitor voltage reaches a predetermined threshold. This pulse samples a saw-tooth voltage to pick-off a voltage proportional to the logarithm of the initial charge on the capacitor and this voltage is displayed on a log scale meter. The ionisation chamber and capacitor may be separate from the remainder of the apparatus so that one measuring unit may serve a plurality of ionisation chambers. The apparatus may be used to measure pulses from accelerators or X-ray generators or the decay of radio-elements or used in photometry.
