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 !
