Charge Sensitive Amplifier Circuits

Attached is a document describing 2 commercial charge sensitive amplifier circuits and one experimental circuit., all variations on the same basic design devised by Ortec in the 60s. Input and output results are shown for the experimental circuit. The experimental circuit is set up for ZnS(Ag) or NaI(Tl) scintillators, but could be used with plastic scintillators by substituting a charge storage capacitor 10-20 times smaller than shown in the schematic, and a reset resistor 10-20 times larger. As usual, food for thought and grounds for further research. I'm not done tinkering yet...
