论文摘要
广场红外调查望远镜（WFIRST）将回答有关黑暗能源随时间演变的基本问题，并将已知系外行星的目录扩展到参数空间的新区域。 WFIRST使用Hubble大小的镜子和18个新开发的HGCDTE 4K光电二极管阵列（H4RG-10），将测量数亿个星系的位置和形状，成千上万的超级novae的光曲线，以及朝着Galaxy的超级甲壳虫的微角度信号，并具有微连接的信号。这些测量结果需要空前的灵敏度和宽场仪器（WFI），尤其是其检测器的表征。 WFIRST项目实施了广泛的检测器开发计划，以创建满足这些科学要求的焦平阵列。这些原型探测器已被表征，其性能在相关的太空环境（热真空，振动，声学和辐射测试）中表现出来，将H4RG-10的技术准备水平（TRL）推进到TRL-6。我们介绍了这些TRL-6演示设备的性能特征。
The Wide-Field Infrared Survey Telescope (WFIRST) will answer fundamental questions about the evolution of dark energy over time and expand the catalog of known exoplanets into new regions of parameter space. Using a Hubble-sized mirror and 18 newly developed HgCdTe 4K x 4K photodiode arrays (H4RG-10), WFIRST will measure the positions and shapes of hundreds of millions of galaxies, the light curves of thousands of supernovae, and the microlensing signals of over a thousand exoplanets toward the bulge of the Galaxy. These measurements require unprecedented sensitivity and characterization of the Wide Field Instrument (WFI), particularly its detectors. The WFIRST project undertook an extensive detector development program to create focal plane arrays that meet these science requirements. These prototype detectors have been characterized and their performance demonstrated in a relevant space-like environment (thermal vacuum, vibration, acoustic, and radiation testing), advancing the H4RG-10's technology readiness level (TRL) to TRL-6. We present the performance characteristics of these TRL-6 demonstration devices.
