Paul L. RichardsAST-0096933Fully lithographed bolometer arrays using Voltage Biased Superconducting Bolometer (VSB) technology will be used to explore planar band-defining filters and RF multiplexers for use with antenna-coupled bolometers and to fabricate and test prototype arrays of antenna coupled hot-electron bolometers with RF multiplexers and filters, and fabricate and test 32 x 32 absorber-coupled focal-plane bolometer arrays. Also work to explore integrating these arrays with a recently developed readout multiplexer that uses only a single SQUID per row of detectors will continue. This technology will provide new high sensitivity detectors in the currently unexplored but astrophysically interesting sub-millimeter part of the electromagnetic spectrum. ***

Paul L.RichardsAST-0096933采用偏压超导测辐射热计(VSB)技术的全光刻测辐射热计阵列将用于探索用于天线耦合测辐射热计的平面频带定义滤波器和射频多路复用器，制造和测试带有射频多路复用器和过滤器的天线耦合热电子测辐射热计的原型阵列，以及制造和测试32 x 32吸收耦合焦平面测辐射热计阵列。此外，将继续探索将这些阵列与最近开发的读出多路复用器进行集成，该多路复用器每行探测器仅使用一个SQUID。这项技术将在电磁光谱中目前尚未探索但具有天体物理学意义的亚毫米部分提供新的高灵敏度探测器。***
