The Tibet AS{gamma} experiment, which has started since January, 1990, is located at an altitude of 4,300m at Yangbaging in Tibet, China (90.5{degree} E, 301{degree} N). The air-shower array is composed of 49 scintillation counters for fast timing (FT), each counter having an area of 0.5 m{sup 2}, in a grid pattern with a spacing of 15 m and 16 density detectors. The density detectors surrounding the FT detectors are planned to select the showers of which core are inside the FT array. For the constant and continuous opeation, the system for laser calibration, the ADC,TDC module calibration and the power check system were installed. A Rb clock is used for the phase analysis of {gamma}-rays.
