M. Gorski, Warsaw 14/08/2009 First look at bad timing in RPC triggers Runs used: 110520 with bad timing as observed by Drift Tubes 101939 where no bad timing was observed Take two following events (N+1,N) . Take two following events (N+1,N)

M. Gorski, Warsaw 14/08/2009 First look at bad timing in RPC triggers Runs used: 110520 with bad timing as observed by Drift Tubes 101939 where no bad timing was observed Take two following events (N+1,N)
Take two following events (N+1,N) Compute Δbx (with orbits) and plot Categories: 1)1-st and 2-nd event not RPC trig 2) 1-st not RPC, 2-nd RPC 3) 1-st RPC, 2-nd not RPC 4) Both RPC
Conclusions – for the moment none But clearly there is a difference between runs Investigations continuing Plan to correlate with trigger position within detector and check with more recent “good” runs
