摘要本基金将用于开发电压偏置超导过渡边缘热辐射计阵列技术,作为地面天体物理学远红外和毫米波长的直接探测器。在这种新型测热计中,强烈的负电热反馈使传感器温度几乎保持恒定。这导致了与使用掺杂半导体热敏电阻的传统热辐射计相比的几个优点。
英文摘要
AST-9731200 Abstract Funds from this grant will be used to develop the technology for arrays of voltage-biased superconducting transition-edge bolometers as direct detectors for ground-based astrophysics at far infrared and millimeter wavelengths. In this new type of bolometer, strong negative electrothermal feedback maintains the sensor temperature nearly constant. This leads to several advantages over conventional bolometers which use doped semiconducting thermistors.
