研究目的
Comparing the Gamma and Electron Response of scintillator detectors to understand the nonproportionality in light yield.
研究成果
The model reasonably reproduces the data for (Eu) and GYGAG(Ce) scintillators, capturing the essential physics of nonproportionality. However, it fails to accurately model the resolution for CsI(Na), suggesting an incomplete understanding of the underlying physics for this material.
研究不足
The model poorly replicates the resolution of CsI(Na), indicating potential overlooked physics issues. The study primarily considers photoelectric interactions, neglecting Compton scatter effects.
1：Experimental Design and Method Selection:
The study involves comparing the nonproportionality as registered by gamma rays and high-energy electrons, using a model to calculate the gamma nonproportionality curve from the electron response.
2：Sample Selection and Data Sources:
Data was acquired with the scintillators (Eu), GYGAG(Ce) and CsI(Na).
3：List of Experimental Equipment and Materials:
Scintillators, photomultiplier tubes, preamplifier, spectroscopy amplifier, multi-channel analyzer, and radioactive sources.
4：Experimental Procedures and Operational Workflow:
The scintillators were mounted on photomultiplier tubes, pulses were shaped and binned, and the system was characterized for linearity and zero-offset.
5：Data Analysis Methods:
The data was analyzed using Gaussian peak fitting and least-squares analysis for energy calibration.
