This award provides funds for construction of a chopping secondary mirror for the Caltech Submillimeter Observatory. This mirror, or subreflector in the terminology of radio astronomy, will provide sky subtraction at all instrument locations and will be especially valuable for continuum instruments such as the Chicago 32-beam photometer/polarimeter. The design of the chopper is similar to one already built for the Submillimeter Telescope (SMT) planned for construction at Mt. Graham.

该奖项为加州理工大学亚毫米波天文台建造斩波式次镜提供资金。这种反射镜，或射电天文学术语中的次反射镜，将在所有仪器位置提供天空减去，对于芝加哥32光束光度计/偏振计等连续谱仪器特别有价值。直升机的设计类似于已经为亚毫米望远镜(SMT)建造的设计，计划在Mt.格雷厄姆。
