Exotic atom experiments place transition-edge sensor (TES) microcalorimeter arrays in a high-energy charged particle-rich environment. When a high-energy charged particle passes through the silicon substrate of a TES array, a large amount of energy is deposited and small pulses are generated across multiple pixels in the TES array due to thermal crosstalk. We have developed analysis techniques to assess and reduce the effects of charged particle events on exotic atom X-ray measurements. Using this technique, the high-energy and low-energy components of the X-ray peaks due to pileup are eliminated, improving the energy resolution from 6.6 to 5.7 eV at 6.9 keV.

减轻带电粒子撞击对用于奇异原子 X 射线实验的 TES 阵列的影响

奇异原子实验将过渡边缘传感器 (TES) 微量热仪阵列置于富含高能带电粒子的环境中。当高能带电粒子穿过 TES 阵列的硅基板时，会因热串扰而在 TES 阵列中的多个像素上沉积大量能量并产生小脉冲。我们开发了分析技术来评估和减少带电粒子事件对奇异原子 X 射线测量的影响。使用这种技术，由于堆积导致的 X 射线峰的高能和低能分量被消除，在 6.9 keV 下将能量分辨率从 6.6 eV 提高到 5.7 eV。
