Description
This study presents the design of a cryogenic electronics system intended for use in liquid-xenon dark matter detectors. In conventional cryogenic experiments, analog signals are transmitted from low-temperature detectors to room-temperature electronics via coaxial cables and multiple feedthroughs. As the scale of detectors increases, the growing number of signal channels complicates engineering and raises costs. We propose a cryogenic electronics architecture that directly performs front-end amplification, analog-to-digital conversion (ADC), and digital signal processing at low temperatures (~165 K). This design drastically reduces the number of signal channels and the complexity of cabling, thereby alleviating integration challenges and cutting costs. Test results demonstrate that the power modules, preamplifiers, and digital systems function stably in a cryogenic environment. The ADC's performance under cryogenic conditions is currently undergoing experimental validation.
