(a) Circuitry diagram for the amplifier. C1 describes the capacitance of the PIPS detector, C2 describes the feedback capacitance, R1 describes the gain resistor and A1 describes the trans-impedence amplifier. (b) The effect of increasing the feedback capacitance on the step response and rise time of the amplifier utilized and comparison with the gridded ion chamber and Keithley amplifier. |
