DTP Seminar DATE: 2012-11-13 16:00 - 17:00 PLACE: Room 345, Building 4, 3rd floor TITLE: Latest results of the ILC Large TPC Prototype (LPTPC) CONTACT: Keisuke Fujii (keisuke.fujii_at_kek.jp) SPEAKER: Dr. Gilles De Lentdecker  (Universite Libre de Bruxelles) LANGUAGE: English URL: http://rd.kek.jp/seminar_01.html ABSTRACT: A Time Projection Chamber (TPC) is a candidate for the central tracker of the future International Linear Collider (ILC) detectors. TPCs have already demonstrated very good performance in past collider experiments. In order to obtain one order of magnitude improvement in momentum resolution and the highest possible track recognition efficiency, the Linear Collider TPC (LCTPC) Collaboration is pursuing R&D activities to find the best state-of-the-art technology for the TPC. For ILC the TPC would have a diameter of 3.6 m and a length of 4.3 m. It should provide 200 space points with pad readout along a particle track, with a spatial resolution of 100 μm in the Rφ plane. To achieve these performances, a TPC equipped with Micro Pattern Gaseous Detectors (MPGD) instead of Multiwire Proportional Chambers (MWPC) is needed. Therefore the LCTPC Collaboration has built a large TPC prototype (LPTPC), with a diameter of 750 mm and a length of 600 mm, which can be equipped with Micromegas or GEMs as amplification structures.
