Parallel Ionization Multiplier (PIM): application of a new concept of gaseous structure to tracking detectors

Abstract : A new amplifying structure has been developed for beta imaging detectors: the Parallel Ionization Multiplier (PIM). PIM is made of a thin sandwich of two metallic micromeshes separated by a new laser machined insulating spacer. This structure allows high gain (105) with a good efficiency and a two-dimensional spatial resolution below 50 small mu, Greekm without strong discharge limitation. The capabilities of the PIM are now investigated in order to be used by high-energy physics experiments. A prototype of a tracking detector for charged particles using the PIM structure will be described. Thanks to the very small avalanche extension, the use of a highly segmented anode is possible. This detector would support high rate running conditions of hadron experiment.
