Abstract

In this study, having designed the electronics readout and an appropriate PIN diode, the digital alpha-particle spectroscopy was undertaken by an external sound card digitizer. The designed electronic circuit simulation was performed using the LTSpice simulator. On the other hand, since the appropriate choice of digital pulseshaper considerably improves the performance, a fast and easy-to-use pulse shaper was incorporated. A digital pulse-shaper based on a band-pass filter was also designed for the waveforms digitized by the sound card. The results of the energy resolution of the proposed pulse-shaper were compared with the results of conventional digital ones (i.e., trapezoidal, cusp-like, and FFT cusp-like). The results showed that band-pass filter-based pulseshaper also improved the energy resolution as expected. The main advantages of the proposed pulse-shaper are its pulse-shaping speed (40% faster than the conventional ones) and ease of use (without needing to regulate parameters).
