Micropattern gaseous detectors (MPGD) are a recent technology, applied in the construction of large area detectors, with good spatial and energy resolution, as well as high counting rate capability. Research in MPGD has gained a large momentum and has been giving valuable contribution in many High Energy Physics Experiments over the last few years. This technology is a front edge in radiation detection and a total novelty in Brazil, where no other group is working in this field of Instrumentation. This proposal aims at contributing with the efforts of the ALICE collaboration (A Large Ion Collider Experiment), one of the large experiments of the Large Hadron Collider (LHC) at CERN (l'Organisation Européene pour la Recherche Nucleaire) to upgrade its Time Projection Chamber (TPC) with GEM-based readout chambers and exploit the performance of this type of detectors in innovative interdisciplinary applications. The contribution for their development in terms of detection area, position resolution and simplicity of construction will benefit other sciences, making \hepic (High Energy Physics and Instrumentation Center at USP) emerge as a reference group in the work with MPGD, in Brazil and internationally. Four types of problems will be addressed: - study of the operation conditions of the GEM system to be installed in the LHC-CERN ALICE experiment; - test and integration of the SAMPA ASIC, developed within CERN's ALICE collaboration, as front end electronics for MPGD in general; - research and development in MPGD; - MPGD applications in the study of historical and cultural heritage with X-rays using large area detectors, and thermal neutron detection for neutron scattering techniques. The SAMPA ASIC will be the charge readout of a position sensitive detection system. The development of Thick-GEM structures is progressing using the Brazilian Industry to replace the GEMs, which are fragile and require a more complex production process. The Thick-GEMs produced will be used in neutron detection as Boron-10-based converters, which are a promising alternative to Helium-3. Deposition tests on copper substrates have already started, with encouraging results. This work will make use of the laboratory infrastructure under development in HEPIC, which is an emerging center in High Energy Physics Instrumentation. (AU)
