Area of Science:

  • Nuclear Instrumentation
  • Spectroscopy

Background:

  • Traditional gamma-ray spectrometers using NaI(Tl)+PMT structures suffer from signal instability due to environmental factors and cable effects.
  • This instability degrades spectral resolution, particularly at high counting rates.

Purpose of the Study:

  • To design and evaluate a novel reset charge sensitive amplifier (RCSA) for NaI(Tl)+PMT gamma-ray spectrometers.
  • To improve spectral resolution and stability under challenging conditions, including high counting rates and temperature variations.

Main Methods:

  • Developed an RCSA integrating a basic amplifying circuit, a reset circuit, and a dark current compensation circuit.
  • The RCSA outputs a step signal, which is then processed by a CR differentiating circuit for stable time constants.
  • Implemented a digital shaping algorithm within a digital multi-channel analyzer (DMCA) to process the RCSA output.

Main Results:

  • The RCSA demonstrated a charge sensitivity of 4.26×10^10 V/C, with low noise characteristics (51.09 fC zero capacitance noise, 1.98 fC/pF noise slope).
  • The system maintained good energy resolution at counting rates up to 150 kcps.
  • Stable performance was observed across a wide temperature range of -19°C to 50°C.

Conclusions:

  • The designed RCSA effectively overcomes the limitations of traditional front-end circuits in gamma-ray spectrometers.
  • The RCSA, coupled with digital signal processing, enables robust and high-resolution spectroscopy in demanding environments.
