Abstract

This is to report on our progress and current status of the Sub-Millimeter Array (SMA) project in Taiwan. In particular, we will describe the development of the SMA receiver systems. The SMA is the first major instrumentation project in the Taiwanese astronomical research community. The primary design and development of the SMA receiver system has been carried out in the receiver laboratory at the Smithsonian Astrophysical Observatory (SAO). We have undertaken the system assembly, integration and testing, and the task to fabricate the superconductor-insulator-superconductor (SIS) mixers used for our SMA receivers. The system will be initially equipped with two SIS receiver modules to cover 176 - 256 GHz and 250 - 350 GHz bands, followed with a third band of 600 - 720 GHz. The receiver system will be installed in the antenna in the mid-2000. The major milestone for this project is to ship the antennas to Mauna Kea, Hawaii to join the rest of the SMA for testing interferometric observation before the end of the year 2000.
