Abstract

We have developed a GEM-TPC for H-dibaryon search at J-PARC E42, which reconstructs charged particles from the H-dibaryon decay in (K -,K+) reaction. Since 106 cps/cm2 K- beams are injected to the TPC, GEMs and a gating grid are adopted to suppress positive ion feedback. The TPC is also designed to have good position resolutions corresponding to the ΛΛ invariant mass resolution of a few MeV/c2. The design of the E42 TPC, and performance evaluations of a prototype TPC are described.
