An RLC circuit simulation design for nuclear pulse shaping

The waveform of nuclear pulse output from charge sensitive preamplifier is exponential. The peak of exponential pulse is often very sharp, so the real maximum point cannot be sampled accurately, and the amplitude of the pulse is difficult to acquire accurately. So exponent shaped pulse is always shaped to other waveform, and the peak of the shaped pulse is flat or smooth. The shaping circuits in some textbooks or documents are often complex, and whose parameters are usually hard to adjust. To improve the energy resolution of the spectrometer, in this paper, an RLC circuit simulation design for nuclear pulse shaping is designed. This circuit has outstanding merits of very simple structure, convenient adjustment and strong capability of noise suppression. And simulation design is convenient for circuit optimization. Analysis and experiment show that this circuit is a feasible solution for nuclear pulse shaping.
