1 Beam pipe geometry for GLD’ and ILD_G2
2008年3月18日 杉本康博

2 Geometry for GLD’ VTXまわりだけを変更 CCD: 50+30 mm Si ASIC: 100+30 mm Si
Layer R (mm) 3T R (mm) 3.5T R (mm) 4T BP 15 14 13 L1 17.5 16 L2 19.5 18 17 L3 38 37 36.5 L4 40 39 38.5 L5 58 L6 60 CCD: mm Si ASIC: mm Si

3 Beam pipe for GLD’ R (mm) Z (mm) A 15/14/13 80 B 34 250 C 350 D 1100

4 VTX for ILD_G2

5 Beam pipe for ILD_G2 Axial symmetry w.r.t detector Axial symmetry
w.r.t exit beam Pair background at Z~2.3m should be studied with anti-DID

6 Background clearance

7 Backup slides

8 これまでの議論 Phone meeting chaired by Marco Battaglia
2種類のconfiguration: 5-layers/3-doublets |cosq|<0.95 for inner layers Marc Winterは途中で切断 Consensus document draft by Marco Optimization W.G. meeting on 2/27 MarcのグループのDamienがgeometryを見せた しかしMarcoのdraftとは異なっている Discussion with Marc at TILC08 Feasibilityに疑問は残るがDamienの示したgeometryの線で検討することに合意 Consensus document の改訂版をMarcが今月中に用意して、VTX communityに回し、合意が得られればOptimization W.G.に送る
