Abstract
ChangʹE-2 gamma-ray spectrometer (GRS) is included in the payload of Chinese second lunar mission ChangʹE-2 that has been launched in October 2010. Specific objectives of the GRS are to map abundance of O, Si, Fe, Ti, U, Th, K, and, perhaps, Mg, Al, and Ca, to depth of about 20 cm. The energy resolution and detection efficiency were improved compared with ChangʹE-1 GRS. We will describe the design of GRS, which used LaBr3 for its main detector, and present its performance in this paper. Moreover, the initial result of ChangʹE-2 GRS is reported.
