Title: The TRIC Experiment: A P-even Time-Reversal Invariance Test at COSY

At the cooler synchrotron COSY at Juelich a novel (P-even, T-odd) true null test was proposed, that is supposed to measure the time-reversal invariance sensitive observable, the total cross-section correlation Ay,xz, to an accuracy of 10-6. This observable is measured in a transmission experiment of a circulating vector polarized (Py) proton beam through an internal tensor polarized (Pxz) atomic deuteron target. The experiment uses the COSY facility as an accelerator, an ideal forward spectrometer, and as a detector. At present the experimental focus lies on the development of a precise current measurement via a Beam-Current-Transformer (BCT), its precise read-out and analysis. So far, we succeeded to meet the BCT's accuracy specification. With the help of this accurate current measurement the development of a proper long living proton beam in COSY at the optimum energy, where the experiment has its highest sensitivity, is in progress.
