  1. Some Result of HyCal Resolution Liyang Jiang CIAE/UNCW

  2. Energy Resolution of PWO

  3. General Information • Run: 4280; • Crystal: centered on W2016 for 5 minute deep statistics run; • Hycal Calibration Constants: gain5_iter; • Landau*Gaussian Fit.

  4. Fitting Results (PWO) Eg=5.47GeV Eg=4.76GeV Eg=3.09GeV Eg=2.27GeV

  5. Linearity of Ec at PWO E cluster (GeV)

  6. Sigma/E vs Eg at PWO

  7. Energy Resolution at Lead Glass

  8. Information • Run: 4279; • Crystal: centered on G657 for 5 minute deep statistics run; • Hycal Calibration Constants: gain5_iter; • Landau*Gaussian Fit.

  9. Fitting Results (Glass) Eg=5.47GeV Eg=4.76GeV Eg=3.09GeV Eg=2.27GeV

  10. Linearity of Ec at Glass E cluster (GeV)

  11. Sigma/E vs Eg at Glass

  12. Position Resolution at PWO

  13. Gaussian Fit Results (PWO) Eg=5.47GeV Eg=4.76GeV X (cm) X (cm) Eg=3.09GeV Eg=2.27GeV X (cm) X (cm)

  14. X VS E gamma (PWO) X (cm)

  15. X sigma VS E gamma (PWO)

  16. Position Resolution at Glass

  17. Gaussian Fit Results (Glass) Eg=5.47GeV Eg=4.76GeV Eg=3.09GeV Eg=2.27GeV

  18. X VS E gamma (Glass)

  19. X sigma VS E gamma (Glass)

  20. Position Resolution at Different Place

  21. PWO Information • Run: 5348 (Second Snake Scan) • Scan from W1884 to W1851

  22. Fitting Results

  23. Sigma Y VS X (PWO)

  24. Erratum in Logbook Beam-on modular id of Run 4279 • Logbook, page 240, Run 4279: “Centered on Glass 587 – deep statistics”; • Online database, Run 4279: “Centered on G657 for 5 minute deep statistics run”.

  25. Erratum in Logbook • Information from EPICS bank; • Reconstructed X and Y position; • Energy deposit in each modular.

  26. Erratum in Logbook Position info in EPICS bank • In EPICS bank, the value of position is not changed through Run 4279. • ptrans_x.RBV =448.47 mm, • ptrans_y.RBV =257.37 mm.

  27. Erratum in Logbook Reconstructed position X=-44.34 cm Y=-25.53 cm

  28. Erratum in Logbook Mean Energy deposited in each modular (T counter 30)

  29. Erratum in Logbook Conclusion • The evidence listed above proved that in Run 4279, the beam is hit on the modular G657. The note about Run 4279 in the logbook Page 240 “Centered on Glass 587 …” should be “Centered on Glass 657…”. • NO Lead Glass modular numbered 587.
