研究目的
To introduce and validate the Normally-Distributed Crosstalk Model (NDCM) for silicon photomultipliers, comparing it with existing models and experimental data.
研究成果
The Normally Distributed Crosstalk Model (NDCM) offers a device-specific parameter ?? related to OCT propagation paths, providing probabilities comparable to other analytical models. Initial analysis for the CHEC-S camera suggests ?? ≈ 5 microcells for ?? = 0.5, indicating that OCT photons propagate a significant distance from the original microcell. Ongoing work aims to relate ?? to architectural parameters and introduce further mechanisms into NDCM.
研究不足
The study suggests that while the NDCM provides a good fit to experimental data, further analysis is required to improve understanding of the distribution close to the original microcell. The model's accuracy may be affected by the size of the pixel and the propagation distance of OCT photons.
1：Experimental Design and Method Selection:
The study introduces the NDCM, a new model for predicting optical crosstalk in SiPMs, and compares it with the Borel and nearest-neighbour models through Monte Carlo simulations.
2：Sample Selection and Data Sources:
Experimental data from the CHEC-S camera developed for the Cherenkov Telescope Array is used for comparison.
3：List of Experimental Equipment and Materials:
Silicon photomultipliers and the CHEC-S camera are the primary devices used.
4：Experimental Procedures and Operational Workflow:
Monte Carlo simulations are conducted to investigate the behavior of NDCM at different values of ?? and ??, comparing the results with experimental data and other models.
5：Data Analysis Methods:
The probability of triggering additional microcells is analyzed using a 2-d normal distribution, with comparisons made to the Borel and nearest-neighbour models.
