Abstract

University of Tokyo is now planning to construct a new 6.5m telescope on a peak at Chajnantor region of Atacama, Chile. This project is called "Tokyo Atacama Observatory" (TAO), and site testing is now under progress. As a part of this site testing, we have developed a portable DIMM system which is called a "University of Tokyo DIMM" (UT-DIMM) to measure seeing. The system mostly consists of inexpensive commercial products, which are a MEADE 12 inch telescope, a video-rate CCD camera with an electronic shutter, a Linux based PC, and so on. It has thrifty power consumption and can be operated for one whole night only with a single DC-12V battery for an automobile. In this paper, we describe the instrument, report the current status, and explain its future plans.
