2. Y. Karadzhov, MICE CM26 24 March Slide 2 TOF Calibration - Trigger TOF1 TOF 0 TOF 1 TOF 2 The blue line encloses the calibrated area in the TOF stations.

3. Y. Karadzhov, MICE CM26 24 March Slide 3 TOF Calibration - Trigger TOF1 Time resolution after the calibration : TOF0 – 51ps; TOF1 – 62ps; TOF2 – 52ps. Why the resolutions of TOF1 and TOF2 are different since the two detectors are identical?

4. Y. Karadzhov, MICE CM26 24 March Slide 4 TOF Calibration - Trigger TOF0 Time resolution after the calibration: TOF0 – 50ps; TOF1 – 63ps; TOF2 – 51ps.

This problem is visible only in TOF2 and KL.

6. Y. Karadzhov, MICE CM26 24 March Slide 6 Conclusions 1.Calibration for trigger in TOF0 and TOF1 is available. 2.Why TOF1 resolution is worse? Puzzle that has to be solved. 3.Data quality is not good.
