  1. A study of tracker resolution by Satellite 宮本彰也 2008年6月4日 ACFA-SIM-J meeting

  2. B dependence of srj B: 3  4T, srf and Pt improves by 25% at High momentum

  3. Geometry Dependence of DK <Dk> is the avarage of Dk of three geometry results

  4. Costh dependence

  5. Pt resolution at low momentum Material thickness in unit of radiation lngth (%) From http://ilcphys.kek.jp/soft/geom2/geantino/ScanSummary.htm when multiple scattering dominates j4ldc would be about 15% better than gldapr08 at low momentum if fiited by TPC only Satellite fitting uses TPC+IT+VTX. Difference would be smaller

  6. Backup

  7. Control of TPC spatial resolution If $SATELLITESROOT/macros/S4Macros.C is used, TPC spatial resolution formula can be selected by S4TPC.SpatialResolution. = flat: constant in rphi and Z = experimental: formula implemented by Yamaguchi san = ILD or ILDAuto: ILD formulardescribed by the previous page. If ILD, q1 term is not scaled by Bfield. ILDAuto is default( Scaled by B) JSF parameter name and default values. They are defined in $SATELLITES/macros/S4Macros.C p1=S4TPC.Sig00 [ 0.005 ] p2=S4TPC.Sig0SinDep [0.090] q1=S4TPC.SigLDep [ 0.00053 ] r1=S4TPC.SigmaZ [0.040] S4TPCHit::SetXXXXX can be used to set parameters.

  8. About TPC Resolution Formula suggested by TPC experts: Ron and KeisukeRef) Mail to ild-detector-optimization mailing list, 22-Feb-2008
