莱顿查南托望远镜（Leighton Chajnantor Telescope，LCT）项目由上海师范大学、加州理工学院和康塞普西翁大学共同发起，旨在将加州理工学院亚毫米波天文台（CSO）[1]从夏威夷的莫纳克亚山搬迁到智利查南托高原的拉诺德查南托天文台（Llano de Chajnantor Observatory）。LCT将配备一个新的345 GHz波段外差阵列接收器，具有3×3光束和量子极限灵敏度。基于超导Nb/Al-AlOx/Nb隧道结（SIS）混频器，我们研制了一种紧凑的1×3阵列作为新型外差阵列接收机的一个单元。详细的设计和测量结果将被呈现。
The Leighton Chajnantor Telescope (LCT) project, sponsored by Shanghai Normal University in collaboration with Caltech and the University of Concepción, is seeking to relocate the Caltech Submillimeter Observatory (CSO)[1] from Mauna Kea, Hawaii to Llano de Chajnantor Observatory on the Chajnantor Plateau in Chile. The LCT will be equipped with a new 345-GHz band heterodyne array receiver of 3×3 beams and quantum-limited sensitivity. Based on superconducting Nb/Al-AlOx/Nb tunnel junction (SIS) mixers, we have developed a compact 1×3 array as one unit of the new heterodyne array receiver. Detailed design and measurement results will be presented.
