A beam polarimeter for medium-energy protons and deuterons has been constru
cted. Its operation is based on the elastic-scattering reactions (p) over r
ight arrow + p or (d) over right arrow + p. The outgoing particles are dete
cted in kinematical coincidence in four independent reaction planes, each e
quipped with two pairs of phoswich detectors. (C) 2001 Published by Elsevie
