Performance Analysis of MRPC Telescopes in the EEE Project

Detailed examination of the performance of MRPC telescopes in the EEE Project, focusing on topics such as time resolution, time slewing correction comparison, beta distributions, and Time Over Threshold strategy for time correction. The analysis involves understanding contributions, applying corrections, and investigating possible signal reflections. Progress updates from various meetings are discussed with a special emphasis on improving time resolution and correction methods.

1. Performance of MRPC telescopes of the EEE Project E. Bossini, C. Cical , D. De Gruttola, I. Gnesi, M. Garbini, S. Grazzi, M.P. Panetta EEE meeting 30/11/2016

2. Status time resolution time slewing correction comparison between old and new analyzer spatial resolution time slewing correction comparison between old and new analyzer beta ditributions for all telescopes (ongoing, not shown here) trending for HV and currents (ongoing, not shown here) duty cycle by trending the rate (ongoing, not shown here) writing (well advanced, not shown here) EEE meeting 2 30/11/2016

3. Time Over Threshold strategy for the time slewing correction understand all contributions EEE meeting 3 30/11/2016

4. TOT TOT vs time to get time slewing corrections next use the mean of distribution bin by bin (at the moment we use the mean of the profile) clarify possible reflections (peaks in the TOT distribution) apply time slewing correction and measure again the time resolution apply correction on single signals (left and right) rather than to the mean of TOT in a chamber EEE meeting 4 30/11/2016

5. TOT TOT vs time to get time slewing corrections next use the mean of distribution bin by bin (at the moment we use the mean of the profile) clarify possible reflections (peaks in the TOT distribution) apply time slewing correction and measure again the time resolution apply correction on single signals (left and right) rather than to the mean of TOT in a chamber EEE meeting 5 30/11/2016

6. TOT TOT distributions (secondary peaks are visible signal reflections?) EEE meeting 6 30/11/2016

7. TOT vs strip TOT vs strip signal to investigate the possible dependece of reflections y (cm) strip signal from cluster top chamber left side TOT (ns) EEE meeting 7 30/11/2016

8. TOT vs strip TOT vs strip signal to investigate the possible dependece of reflections y (cm) strip signal from cluster top chamber right side TOT (ns) EEE meeting 8 30/11/2016

9. TOT vs strip TOT vs strip signal to investigate the possible dependece of reflections y (cm) strip signal from cluster mid chamber left side TOT (ns) EEE meeting 9 30/11/2016

10. TOT vs strip TOT vs strip signal to investigate the possible dependece of reflections y (cm) strip signal from cluster mid chamber right side TOT (ns) EEE meeting 10 30/11/2016

11. TOT vs strip TOT vs strip signal to investigate the possible dependece of reflections y (cm) strip signal from cluster bot chamber left side TOT (ns) EEE meeting 11 30/11/2016

12. TOT vs strip TOT vs strip signal to investigate the possible dependece of reflections y (cm) strip signal from cluster bot chamber left side TOT (ns) EEE meeting 12 30/11/2016

13. TOT TOT distributions (secondary peaks are visible signal reflections?) TOT vs strip show no dependence on the strip the effect seems to be slightly important in the mid chamber is it correct to use the mean of TOT1 and TOT2? tL=tL tR=tR t =tL 2 *- f(TOTL) *- f(TOTR) *+tR - f TOTL+TOTR 2 * it should work, but taking reflections into account (NINO and electronic chain) the correction should be done on single signals (left and right) to be done EEE meeting 13 30/11/2016

14. Time and spatial resolution comparison between old and new analyzer difference to be understood EEE meeting 14 30/11/2016

15. Time resolution comparison between old and new analyzer TORI-03-2015-10-20 90 runs (4,5x 106events) gaussian fit [-0.1;1.5] ns official plot at the moment = 207 ps = 229 ps new Analyzer (new) 2<5 (strip by strip calibration at CNAF) old Analyzer 2<10 (mean strips calibration at CNAF) EEE meeting 15 30/11/2016

16. Time resolution comparison between old and new analyzer (different sample) TORI-03-2016-04-26 10 runs (4 x 105events) worsening (15-24%) of time resolution due to different p and T conditions? gaussian fit [-0.1;1.5] ns = 245 ps = 302 ps new Analyzer (new) 2<5 (strip by strip calibration at CNAF) old Analyzer 2<10 (mean strips calibration at CNAF) EEE meeting 16 30/11/2016

17. Time and spatial resolution many more details and checks available for discussion EEE meeting 17 30/11/2016
