摘要
我们报告了高能质子射线与基于动力学电感探测器（KID）的Terahertz Intensity Mapper（TIM）焦平面阵列相互作用的效应。TIM是一项由NASA资助的气球载实验,旨在探测宇宙星际形成的峰值。它采用两种红外光谱带,每个带配备由约900像素构成的KID阵列芯片。对864像素TIM阵列的测量显示,791个谐振器覆盖0.5GHz带宽。我们讨论了由于高复用密度导致谐振器校准的挑战。我们使用自定义的基于LED的识别方案可靠地识别了788个（99.6%）探测器的物理位置。利用这些信息,我们显示在阵列中, cosmic ray 事件的发生率为2.1 events/min/cm^2。66%的事件仅影响单个像素,另有33%的事件在0.66cm^2区域内影响<5个KID,跨2个像素间距。我们观察到总体的cosmic ray死亡比例为0.0011%,并预测最大可能的飞行死亡比例为~0.165%,这表明我们的设计将抵御这些高能事件具有鲁棒性。
