MONTR-RCT=/ , During the measurements, the beam polarization was
continuously monitored by two sets of beam line
polarimeters. These polarimeters measured protons
scattered at 17deg from a (CH2)n target in coincidence
with the recoil protons by four detector, which measure
the vertical and horizontal components of the beam
polarization. /;
