Tracking with 40*40 cm$^{2}$ MICROMEGAS detectors in the high energy, high luminosity, COMPASS experiment

Large size 40x40 cm sup 2 gaseous microstrip MICROMEGAS detectors are used for the charged particle tracking in the COMPASS experiment at CERN. The commissioning was performed using a 160 GeV muon beam of up to 1.5x10 sup 8 particles per SPS spill. Position resolution of <=70 mu m and timing reso...

Sumario:Large size 40x40 cm sup 2 gaseous microstrip MICROMEGAS detectors are used for the charged particle tracking in the COMPASS experiment at CERN. The commissioning was performed using a 160 GeV muon beam of up to 1.5x10 sup 8 particles per SPS spill. Position resolution of <=70 mu m and timing resolution of <=10 ns are achieved. A printed circuit board of 60x120 cm sup 2 surface and 100 mu m thickness allows to move the front-end electronics components outside of the spectrometer acceptance, hence keeping the amount of material within acceptance minimum. These detectors fulfill the stringent requirements of the COMPASS spectrometry.
