Wire efficiencies on the second chamber are in the lower .70's. Beam current is up around 8.2 uA and V_eff's are low by ~ 5 V. I adjust them after run 3539. Chamber efficiencies are not significantly affected. Tracking efficiency w/ 15 planes is now ~ .75, 0.28 w/ 13.
Shift is running well - production at 8 uA.
Shown below are chamber efficiencies with vertex, energy, and chi^2/d.o.f. cuts included.
