概要 | 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 10(6) cps/cm(2) 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 Lambda Lambda invariant mass resolution of a few MeV/c(2). The design of the E42 TPC, and performance evaluations of a prototype TPC are described. |
