Charge amplifier using Teledyne Philbrick 102601 opamp was developed for use with each Geiger counter of 132-counter array for ionization hodoscope used in tracing paths of cosmic rays. Charge-sensitive stage A1 converts input charge pulse tovoltage pulse significantly larger than noise of second stage. With 616-pF load capacitor, output is 12 V for input of 10 mV. Cost of charge amplifier is about $50.-H. C. Carpenter, Low Cost Charge Amplifier, EDN Magazine, May 20, 1973, p 83 and 85.
