1 Y. Karadzhov, MICE Video Conference 25-feb TOF Calibration - Trigger TOF1 TOF 0 TOF 1 TOF 2 The blue line encloses the calibrated area in the TOF stations.

2 Y. Karadzhov, MICE Video Conference 25-feb TOF Calibration - Trigger TOF1 Time resolution after the calibration: TOF0 – 51ps; TOF1 – 62ps; TOF2 – 52ps.

3 Y. Karadzhov, MICE Video Conference 25-feb TOF Calibration - Trigger TOF0 The blue line encloses the calibrated area in the TOF stations. TOF 2 TOF 0 TOF 1

4 Y. Karadzhov, MICE Video Conference 25-feb TOF Calibration - Trigger TOF0 Time resolution after the calibration: TOF0 – 50ps; TOF1 – 63ps; TOF2 – 51ps.

5 Y. Karadzhov, MICE Video Conference 25-feb To avoid the confusion, the calibration is documented in the logbook. Message in the logbook

6 Y. Karadzhov, MICE Video Conference 25-feb How to get the Time of Flight faster? vector tof0sp = tofRec.GetSpacePoints( 0 ); if( tof0sp.size()==1 ) t = theEvent.tofSpacePoints[ tof1sp[0] ]->time(); vector tofUpTrack = tofRec.GetUpStreamTracks(); vector tofDownTrack = tofRec.GetDownStreamTracks(); if( tofUpTrack.size()==1 ) tof = theEvent.tofTracks[ tofUpTrack[0] ]->GetTimeOfFlight(); Here we select TOF0 // this is the time measured by TOF0 // Tracks between TOF0 and TOF1 // Tracks between TOF1 and TOF2 // this is the time of flight between TOF0 and TOF1 This is a faster access to the data. I recommend to use this in the online applications.

This problem is visible only in TOF2. Shifters should pay more attention on this.
