Abstract
The circular electron positron collider (CEPC) is proposed to research Higgs, and particle flow algorithm (PFA) is expected to be adopted to obtain high energy resolution. As a PFA calorimeter, CEPC hadronic calorimeter (HCAL) features fine granularity, which necessitates high integration, low noise, and low power consumption in readout electronics. The scintillator-based analog HCAL (AHCAL), one of the PFA HCAL technical approaches, has been studied. In this article, a readout system of the CEPC AHCAL prototype is designed and implemented. The system can not only read the signals of high-density silicon photomultipliers (SiPMs) but also calibrate SiPM gain and monitor temperature. Testing of the electronics demonstrates that the noise and dynamic range performances meet the requirements. Following mess production and prototype integration, cosmic ray tests and beam tests are conducted, with all results verifying the functionality and performance of the readout system.
期刊介绍：
The IEEE Transactions on Nuclear Science is a publication of the IEEE Nuclear and Plasma Sciences Society. It is viewed as the primary source of technical information in many of the areas it covers. As judged by JCR impact factor, TNS consistently ranks in the top five journals in the category of Nuclear Science & Technology. It has one of the higher immediacy indices, indicating that the information it publishes is viewed as timely, and has a relatively long citation half-life, indicating that the published information also is viewed as valuable for a number of years.
The IEEE Transactions on Nuclear Science is published bimonthly. Its scope includes all aspects of the theory and application of nuclear science and engineering. It focuses on instrumentation for the detection and measurement of ionizing radiation; particle accelerators and their controls; nuclear medicine and its application; effects of radiation on materials, components, and systems; reactor instrumentation and controls; and measurement of radiation in space.
