CRYOSEL项目提出利用超导单电子器件(SSED)探测声子信号,以排除锗低温探测器中无电离信号的背景,首个原型机的红外激光脉冲响应测试验证了该传感器技术的可行性。

摘要:

使用低温探测器搜寻轻暗物质(DM)粒子的灵敏度,主要受限于不产生电离信号的大量事件背景。CRYOSEL项目开发了一种新技术,通过使用超导单电子器件(SSED)传感器的信号,来排除锗低温探测器中的这种背景。该传感器旨在探测e$^-$h$^+$对在附近的极强电场区域漂移时,通过Neganov-Trofimov-Luke效应发射的声子。对该器件信号的标记应能抑制仅发热背景。对首个CRYOSEL原型机红外激光脉冲响应的测量表明了此类传感器技术的相关性。

英文摘要:

The sensitivities of light Dark Matter (DM) particle searches with cryogenic detectors are mostly limited by large backgrounds of events that do not produce ionization signal. The CRYOSEL project develops a new technique where this background in a germanium cryogenic detector is rejected by using the signals from a Superconducting Single Electron Device (SSED) sensor designed to detect the phonons emitted through the Neganov-Trofimov-Luke effect by the e$^-$h$^+$ pairs as they drift in a close-by very high-field region. A tag on signals from this device should suppress the heat-only background. The measurement of the response to IR laser pulses of the first CRYOSEL prototype show the relevance of such sensor technology.
