Abstract

This paper describes a comparative study of three optical readout systems for the RIPTIDE detector, focusing on their performance under extreme low luminosity conditions. The systems analysed include the ASI533MM-PRO from ZWO, the ORCA-Quest2 from Hamamatsu, and an MCP-based setup built specifically. A key aspect of this analysis is the method to measure the intensity distribution of the diffraction peaks, produced by a coherent light passing through a single slit to study the photon sensitivity and the noise characteristics of the detectors. A photodiode detector for laser power measurement was used to quantify the total light intensity, which was then correlated with the grey level output recorded by each system. As expected, the results show that the ASI533MM-PRO exhibited lower photon sensitivity and higher background noise than the ORCA-Quest2, which demonstrated the capability of detecting single photons. The MCP setup, despite its higher background noise, benefited from light amplification, enabling detection of lower photon densities. This method of comparison provides a robust framework for evaluating the photon's detection sensitivity of optical readout systems for high-precision, low-luminosity applications like the RIPTIDE detector.

RIPTIDE探测器中候选光子读出系统的传感器性能评价。

本文介绍了三种用于RIPTIDE探测器的光学读出系统的比较研究，重点研究了它们在极低亮度条件下的性能。分析的系统包括来自ZWO的ASI533MM-PRO，来自Hamamatsu的ORCA-Quest2，以及专门构建的基于mcp的设置。该分析的一个关键方面是测量衍射峰的强度分布的方法，该衍射峰是由相干光通过单个狭缝产生的，以研究探测器的光子灵敏度和噪声特性。一个用于激光功率测量的光电二极管检测器用于量化总光强，然后将其与每个系统记录的灰度输出相关联。结果表明，与ORCA-Quest2相比，ASI533MM-PRO具有较低的光子灵敏度和较高的背景噪声，具有探测单光子的能力。MCP的设置，尽管它的背景噪声较高，受益于光放大，使检测较低的光子密度。这种比较方法为评估光学读出系统对高精度、低光度应用（如RIPTIDE探测器）的光子探测灵敏度提供了一个强大的框架。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
