THE CALIBRATION OF SLOW-NEUTRON POLARIZED BEAM INSTRUMENTS

Abstract:
A new procedure for calibrating the efficiencies of the polarisation sensitive components in slow neutron polarised beam instruments is described. The measurement of one "flipping ratio" and two "shim ratios" allows the effective polarisation, the spin flipping efficiency, and a depolarising shim efficiency to be determined unambiguously. Results of its application to the calibration of a neutron time-of-flight polarised beam reflectometer are presented. © 1987.
