Low-Energy Deuteron Polarimeter

Abstract

We built a Low Energy Deuteron Polarimeter which measures the spin-polarization of deuteron beams in the energy range of 25 to 80 keV. This polarimeter works by measuring azimuthal asymmetries in the D(\vec d, n)^{3}He reaction and comparing them to known analyzing powers. We built this polarimeter to test its performance and to cross-check other existing polarimeters at KVI. We were able to use this polarimeter as a vector polarimeter, but not as a tensor polarimeter because of an uncertain 'tensor analyzing power' calibration.
