Development of a Submillimeter-wave Superheterodyne Camera (SuperCam) for the Heinrich Hertz Telescope

0421499—亚利桑那州Walker/U将建造一个亚毫米波外差阵列接收器，用于10米海因里希赫兹望远镜的卡塞格伦焦点。该阵列将在天体物理丰富的870微米大气吸收窗口中运行，在该窗口中，HHT具有世界上任何亚毫米望远镜的最高效率，并且在40%以上的时间内具有出色的大气透射率。超外差相机（SuperCam）将是一个8x8的集成接收器阵列，采用前沿混频器、本地振荡器、低噪声放大器、低温和数字信号处理技术制造。

0421499 -- Walker/U of ArizonaA submillimeter-wave heterodyne array receiver will be constructed for use at the Cassegrain focus of the 10-meter Heinrich Hertz Telescope. The array will operate in the astrophysically rich 870 micron atmospheric absorption window where the HHT has the highest efficiency of any submillimeter telescope in the world and excellent atmospheric transmission more than 40% of the time. The Superheterodyne Camera (SuperCam) will be an 8x8, integrated receiver array fabricated using leading-edge mixer, local oscillator, low-noise amplifier, cryogenic, and digital signal processing technologies.
