A vector and tensor polarimeter for high-energy deuterons

The characteristics of a polarimeter to measure the tensor polarization of deuterons with energy of a few GeV have been studied by Monte Carlo simulat ions. The analyzing reaction is forward elastic dp scattering. The results of the simulation have been verified with a prototype hydrogen cell and a r ecoil proton detector using drift tubes inserted in the polarimeter POMME. The test used a vector and tensor polarized deuteron beam of 1.6 GeV kineti c energy at the accelerator Saturne. The feasability of a vector and tensor deuteron high-energy polarimeter based on deuteron-proton elastic scatteri ng reaction has been studied. We present here the prediction of a Monte Car lo simulation and the first results of a test made with a prototype, at the Saturne National Laboratory. (C) 1999 Elsevier Science B.V.
