A high pressure 4He polarimeter for double scattering experiments
Abstract
We describe the performance of a high pressure (up to 50 bar) 4He polarimeter designed as the second scatterer in nuclear double-scattering experiments for protons and deuterons at energies up to 12 MeV. The main characteristics are an efficiency of ∼3 × 10 -5 and an effective analyzing power of 0.7-0.8 for protons (measured at a pressure of 20 bar). For deuterons the efficiency is estimated to be of the same order of magnitude whereas the effective analyzing power is about half the magnitude. The polarimeter is equipped with several beam monitoring devices and can be moved along its symmetry axis as well as rotated around it.
