Abstract ALICE is one of the four major experiments installed in the Large Hadron Collider (LHC), at the European Center for Nuclear Research (CERN). An update plan has recently been approved, where several improvements in resolution and tracking efficiency in heavy ion collisions, despite an improvement of the event production rate to around 50kHz, are foreseen. This proposal aims to an involvement in the updates for the Time Projection Chamber (TPC) and for the Muon Spectrometer. Currently, the TPC in ALICE uses Multiwire Proportional Counters (MWPC) for multiplication of the electrons generated by particles crossing the active region of the detector. This technology has limitations that negatively influence the broad scientific program of the experiment. Therefore, the MWPC will be replaced by Gas Electron Multipliers (GEM). In the Muon Spectrometer, taking into account the considerable increase in the event production rate, a reduction of the readout time of the signals to 20 us is mandatory. All these improvements require an update of all the electronics in these subdetectors. The development of a new ASIC which meets the requirements of the TPC and Muon Spectrometer updates has been proposed to the ALICE collaboration. This document is a proposal for the funding of a post-doctoral grant, aiming the development of GEM-based detectors suited for testing the ASIC under development in realistic working conditions. The developed work will serve as the start of a support infrastructure for the tests of the electronics. The use of other Micropattern Gaseous Detectors with the newly developed electronics is also foreseen, aiming the broadening its application fields, for example, to calorimetry or medical sciences.
