Description
A collaboration between USP Physics Institute and the Microelectronics Department of the USP Polytechnic School has been the main developer of a front-end ASIC, named SAMPA, for the readout of gaseous detectors. The ASIC was originally developed to instrument the new Gas Electron Multiplier (GEM) readout plane of the ALICE Time Projection Chamber, as well as to upgrade the front-end of the Multi Wire Proportional Chamber of the ALICE Muon Tracker, becoming soon also the choice for the electronics of other high energy & nuclear physics experiments. Each of them developed its own, custom, front-end board to host the ASIC, designed to fit its custom acquisition system, very performant, but too complex for smaller experiments or laboratory activities.
To make SAMPA widely available and usable, we designed a front-end board, compatible with the Scalable Readout System developed by the RD51 community and developed the necessary firmware and acquisition software to operate it. We will present the results of the commissioning and testing with a detector of this readout system, highlighting performance and capabilities. It is working as expected and could be a useful tool for small experiments and/or in the R&D phase of new detectors (e.g., test beam of prototypes).
