Analysis of systematic errors in the NOPTREX Experiment.

The Neutron Optics Parity and Time Reversal EXperiment (NOPTREX) will search for possible parity (P) and time (T) reversal invariance violating effects in propagation of polarized neutrons through a polarized target. In the proposed experiment polarization of an initially unpolarized neutron beam (P) and the asymmetry of initially polarized neutron beam (A) in propagation through a polarized target are measured. The difference between measured polarization and asymmetry would indicate the presence of PT-violating interaction. In this talk, we present analysis of various systematic uncertainties that can arise from various types of deviations from the idealized conditions. *This material is based upon work supported by the U.S. NSF under award OIA-1355438 and the U.S. Department of Energy, Office of Science, Office of Nuclear Physics, under Award Number DE- SC0014622.
