MPGD simulation in negative-ion gas for direction-sensitive dark matter searches
Hirohisa Ishiura, Rob Veenhof, Kentaro Miuchi +1
Negative-ion time projection chambers (NITPCs) provide the absolute z-position from the arrival-times' difference of several species of negative-ions. This is a strong background r…
Development of a time projection chamber with a sheet-resistor field cage
Kentaro Miuchi, Tomonori Ikeda, Hirohisa Ishiura +12
A new-concept time projection chamber (TPC) using a commercial resistive sheet, sheet-resistor micro-TPC SR-microPIC, was developed and its performance was measured. SR-microTPC ha…
Development of an alpha-particle imaging detector based on a low radioactivity micro-time-projection chamber
H. Ito, T. Hashimoto, K. Miuchi +5
An important issue for rare-event-search experiments, such as the search for dark matter or neutrinoless double beta decay, is to reduce radioactivity of the detector materials and…
Prototype Analog Front-end for Negative-ion Gas and Dual-phase Liquid-Ar TPCs
Miki Nakazawa, Tetsuichi Kishishita, Masayoshi Shoji +8
We report on the recent development of a versatile analog front-end compatible with a negative-ion -TPC for a directional dark matter search as well as a dual-phase, next-genera…
