These polarimeters are separated by a bend angle of 98deg, thus the horizontal and vertical components of the polarization vector can be determined simultaneously. Each polarimeter consists of four arms of collimated pairs of confugate-angle plastic-scintillator telescopes. The polarimetry is based on the analyzing power of the 1H(p,p)1H scattering. /; /* Experimental Method: - Time-of-flight (To measure neutron energy) - Double scattering (To measure neutron polarization) RCT=208PB(P,N)X; PHQ=POL-TRNSF'148'; /* '148' Polarization transfer coefficient, D(L',L).
