PPT-gating grid concept for ALICE upgrade

Howard Wieman 4282014 4282014 1 4282014 2 The Technical Design Report for the TPC Upgrade of the ALICE Time Projection Chamber outlines a plan to use GEM detectors for the TPC readout in which there is an estimated positive ion back flow into the drift volume which is 1 of the 2000 gas gain This positive ion source was estimated to be 40 times1 the primary ionization and was estimated to cause up to 20 cm distortions of the electron drift path2 The assumed ion species used for the distortion estimation are not those with the lowest ionization potential so the space charge could be composed of possibly slower ions5 in which case still larger distortions would be generated Given the difficulty of dealing with large distortions and the uncertainty in their amplitude a gating grid would be a reasonable consideration As stated in the report the anticipated 50 kHz trigger rate precludes using a gating grid of the conventional form that has been used for PEP4 STAR ALICE ALEPH and others.
