First tests with Micromegas setup at GBAR, CERN
As a first test of the Micromegas setup used for the upcoming beamtime of GBAR, MIPs coming from the PS injection into the AD have been detected on all operating Micromegas.
Micromegas will be used for reconstructing the annihilation vertex of antihydrogen at GBAR. The detectors have been set up recently in the AD-hall and are being tested for the upcoming beam time that starts at the beginning of August. One of the first tests we set up was to detect Minimal Ionizing Particles (MIPs) that have been produced after the injection of protons from the Proton Synchrotron (PS) into the Antiproton Decelerator (AD). A scintillator was put in between the Micromegas to give the trigger signal, which was in coincidence with the PS injection. On all Micromegas a clear signal was visible after every trigger.
