We have a plan to operate a new 10 m telescope at Pampa la Bola (4800 m) in Chile as one of Japanese R&D activities for Atacama Large Millimeter/Submillimeter Array. Technical and scientific purposes in this experiment are to develop and evaluate a high precision 10 m antenna under exposed conditions at the site, to develop and test low-noise submillimeter receivers and new SIS photon detectors, to test various techniques for submillimeter observations, and to explore the southern hemisphere in the submillimeter band: Galactic Center, Magellanic Clouds, and so on. The SIS mixer receivers at the Cassegrain focus covers 100, 230, 350, 500, 670, and 810 GHz bands for spectral line observations. A digital autocorrelator consisted of four modules with 500 MHz bandwidth is mounted in a container near the telescope. Two power generators with a capability of 200 kW are installed at the site. The telescope will be operated remotely from Japan via a commercial satellite communication system. After a test operation at Nobeyama for one and a half years, the telescope will be transported to Pampa la Bola in August 2001.
