  1. SMT Assembly & Rates,Take 2 (or 3?) • Changes • Limited tents to Barrels 1&6, layers 1&3 (of 4) • Used Yuri’s tent numbers in addition to nominal tolerance • Calculated for sz = 22 cm as well as sz = 30 cm • Will show • pass rate for nominal tolerance • efficiency at fixed rate (nominal) • Plots over range of “nominal” for pT=1.5 GeV (have 3, infinite)

  2. Trigger Rate s R Increase 1.01 1.05 1.2x 1.05 1.25 1.7x 1.10 1.50 3.4x For calibration, consideran analytic case • Assume gaussian, s =1, but in reality different s • Make a cut at 2.0, and integrate outside. • Make ratio, R, of areas for true s over s=1.0. • Trigger increase is R3
