  7. Moller cross sectiontheta and momentum dependencein Lab system 2000 ×2000 theta momentum GEANT uniform gen. Collimator (-3cm , 12C) HES acceptance >3 [deg] collimator OFF HES

  8. Summary and to do • Summary • HKS GEANT • Committed (subversion) • NMRPort , Chmaber extension2 , flange • MaterialList • Moller scattering • HES cannot accept Moller electrons • to do • Analysis • ee+ background • reconstruct real xx’ distribution with simulation • rejection code • Time difference between ee+ and particles on optics. • Residual of chambers for each arm. • HES tracking • Strangeness 2010 in KEK • registration has been done !
