SuperCDMS检测器中相位分离过渡沿传感器的建模
Modeling phase-separated transition-edge sensors in SuperCDMS detectors
摘要:
SuperCDMS实验实现了过渡边缘传感器来测量Ge晶体中核反冲产生的非热声子。我们讨论了这些TES设备的数值模拟和调整自由模型参数的数据,再现超导正常的相位分离内的TES的程序。这种调谐提供了对TES行为的深入了解,使我们能够研究相位分离长度以优化我们的检测器设计,并集成到SuperCDMS检测器的声子和电荷物理的更完整的模拟中。
英文摘要:
The SuperCDMS experiment implements transition-edge sensors to measure athermal phonons produced by nuclear recoils in Ge crystals. We discuss a numerical simulation of these TES devices and a procedure for tuning the free model parameters to data, which reproduces superconducting-to-normal phase separation within a TES. This tuning provides insight into the behavior of the TESs, allows us to study the phase-separation length to optimize our detector design, and is integrated into a more complete simulation of the phonon and charge physics of SuperCDMS detectors.
