Abstract

We describe the design and construction of a new rapid 3-channel CCD photometer, dedicated to simultaneous multicolor photometric observations of rapidly variable objects. This photometer is equipped on the 1-meter telescope at the Xinglong Observatory. It allows simultaneous imaging within fields of view of 18.8' × 18.8', 18.2' × 17.6' and 9.2' × 9.2' in the Sloan Digital Sky Survey's g', r' and i' bands, respectively. The results of its calibration and performance are reported.
