Abstract
The Center for Axion and Precision Physics Research (CAPP) of the Institute for Basic Science (IBS) is attempting to develop prototype polarimeter detector using gas electron multiplier (GEM) technology for the storage ring proton EDM (SR pEDM) experiment. Systematic errors in the polarimeter mainly come from geometric characteristics of the polarimeter and beam dynamics. Such as beam tilt, shift or detector misalignment etc. can be sources of errors. This investigation of systematic errors has been done with
GEANT4 simulation package modified by ourselves. The modified GEANT4
can calculate spin-dependent hadron elastic cross-section of
proton-carbon scattering, unlike the original one. This research will explain how to realize spin-dependent hadronic elastic scattering in the azimuth angle and demonstrate its application to the geometric error related systematic error study of polarimeter.
