Test of Time-Reversal Invariance at COSY — Dieter Eversheim1, •Yury Valdau1,2, and Bernd Lorentz2 — 1Helmholz Institute für Strahlen- und Kernphysik, University Bonn, Germany — 2Institute für Kernphysik, Forschungszentrum Jülich, Germany
At the Cooler Synchrotron COSY a null test of time-reversal invariance to an accuracy of 10−6 is planned as an internal target transmission experiment. The parity conserving time-reversal violating observable Ay,xz (P-even, T-odd) will be measured using a proton beam energy of 135 MeV. In this experiment, a total double polarized cross section will be measured observing a beam current change due to the interaction of a polarized proton beam with an internal tensor polarized deuterium target from the PAX atomic beam source. Thus, one of the most crucial systems for this experiment is a high precision beam current measurement system, which is in preparation now. The status of this activities, as well as status of the TRIC experiment will be presented in this contribution.
