Abstract
PURPOSE:To regenerate energy data, to remove the error in the input stage of a linear amplifier and to perform accurate measurement, by shaping a waveform to a signal which has lost energy data by differentiation. CONSTITUTION:The electric signal 23 of a semiconductor detector 21 outputs an output signal 24 being an exponential damped waveform through a preamplifier 22. This output signal 24 becomes a stepwise changing signal 26 by a regeneration circuit 25 wherein a resistor R1 is connected to an amplifier A2 on this side and a series circuit consisting of a resistor R2 and a condenser C1 is connected to the input and output terminals of the amplifier A2. In order to prevent the saturation of voltage, a reset current input terminal 27 is provided. By this method, the deterioration of resolving power due to the variation of a rising time can be removed by the regeneration circuit 25 and radiation can be measured accurately.
