N2 - We have evaluated the possibility of the Electron-Tracking Compton Camera (ETCC) to simultaneously operate as a pair-creation camera. The ETCC consists of a gaseous micro-time projection chamber (micro-TPC) and a scintillation camera. Several prototypes of the camera were developed and their performance was studied. Because the micro-TPC can detect a large number of hit points along one charged particle track, has a good position resolution of about 0.2 mm, and uses the filling gas as the scattering material, the influence of multiple scattering is small. This makes the micro-TPC well-suited to detecting pair-creation events. We have examined the performance of a camera of size 10×10×15 cm3, using the pair-creation mode in the energy range of 10100 MeV. Using this camera, we performed a proof-of-principle experiment with laser inverse Compton gamma rays at the National Institute of Advanced Industrial Science and Technology (AIST), and we succeeded in tracking electronpositron pairs and in reconstructing 10 and 20 MeV gamma rays. In this paper, we report the fundamental performance of the gamma-ray camera with pair-creation mode.
