Si & Si/DiamondOptionsAcceptance on BsDsK S. Blusk Group Meeting Mar 31, 2010
Y vs X of Hits (Silicon Only) A B Innermost edge of Si at 7 mm Innermost pixel at 7.5 mm • Start with no gaps • Add 1.1 mm gap btwntwo 6-chip sections • Add 1.1 mm vert. gap btwn left & right half • Increase vertical gapto 3.5 mm C D
Diamond Layout B C • Start with no gaps,hole size 7.5 mm (not shown) • Add 0.6 mm gap btwnSi & Diamond • Add 1.1 mm gap btwn6-chip sections • Add 1.1 mm vert. gap btwn left & right half • Decrease hole sizefrom 7.5 mm 7.0 mm E D
Sil/Diamond Options No gap between Si & Diamond (for comparison) Si/Di gap reduces 4-track eff by ~1.0-1.5% Clearly win back with smaller inner hole size
