For opening a window in MeV gamma-ray astronomy, we are developing an electron-tracking Compton camera (ETCC) having a well-defined point spread function (PSF) and some powerful background rejection tools based on tracking technology of Compton-recoil electron. In 2006, we had the first balloon flight using a small-size ETCC for a demonstration of gamma-ray detection at the balloon altitude (Sub-MeV gamma-ray Imaging loaded on balloon Experiment-I: SMILE-I), and it was successful to observe the intensities of diffuse cosmic and atmospheric gamma rays. As the next step, we are constructing and studying a middle-size ETCC (SMILE-II) using a 30 cm-cubic gaseous electron tracker for the observation of the bright celestial objects. Using SMILE-II ETCC, we validated the effective area, the angular resolution, the background rejection power, and the ability of the polarization measurement by some ground calibrations. In this paper, we summarize the performance and the validation results of SMILE-II ETCC, and present the expectations in the future observations.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"著者人数:
