概要 We have constructed a Time Projection Chamber(TPC) as the 4pi detector for hadron photoproduction experiments at SPring-8. A feature of this TPC is to detect low momentum hyperons as close as 16 mm from the target center. We have studied basic performances of the TPC such as the resolution of dE/dx measurement and the spatial resolution with cosmic rays. The resolution of dE/dx measurement is 16% for minimum ionizing particles. The spatial resolution in pad plane is 280 mum and that along drift direction is 620 Am. The spatial resolution at the distance of 16 mum from the target is obtained to be 400 mum and 880 mum in pad plane and along drift direction respectively.
