Fast Coincidence Filter for Silicon Photomultiplier Dark Count Rate Rejection

Area of Science:

• Physics
• Astrophysics
• Instrumentation

Background:

• Silicon Photomultipliers (SiPMs) offer enhanced angular resolution for neutrino telescopes.
• High dark count rates in SiPMs hinder their practical application.
• Integrating SiPMs with Photomultiplier Tubes (PMTs) is a proposed solution.

Purpose of the Study:

• To develop a fast and resource-efficient method for filtering SiPM dark count rates.
• To mitigate the impact of SiPM dark counts in applications like neutrino detection.
• To validate a novel coincident filtering technique.

Main Methods:

• Development of a low-resource, fast coincident filter.
• Utilizing PMT signals as a trigger to identify and remove SiPM dark counts.
• Implementation and testing of the coincidence filter architecture.

Main Results:

• Successful filtering of Silicon Photomultiplier dark count rates.
• Demonstration of the effectiveness of the PMT-triggered coincident filter.
• Validation of the proposed method through initial experimental results.

Conclusions:

• The developed coincident filter effectively reduces SiPM dark count rates.
• This technique enhances the usability of SiPMs in demanding applications.
• The method shows promise for improving the performance of neutrino telescopes.
