Polarized target for Drell-Yan experiment at COMPASS
Original language description
In the polarized Drell-Yan experiment at the COMPASS facility in CERN a pion beam with momentum of 190 GeV/c and intensity up to 108 pions/s will interact with transversely polarized proton target. The muon pair produced in Drell-Yan process will be detected. The solid-state NH3 as polarized proton target will be polarized by dynamic nuclear polarization at very low temperatures. The maximum polarization reached during data taking is expected to be up to 90 percent. The non-interacting beam and other particles produced inside the target except the muons will be stopped in the hadron absorber after the target. Two target cells, each 55 cm long and 4 cm in diameter separated by a 20 cm gap, will be used. In total the target material volume will be about691 cm3. Drell-Yan data taking is expected to start in 2014-2015 for period of approxi-mately 180 days. The current status of the target, the required modifications and the future plans are presented.
