  1. CM23 -  CKOV Status Report •  CKOV1/2 Installed and cabled in DSA • T %RH recording • Pulser Runs Aug '08 to set HV – MICE Note 225 •  Electron run Sep '08 – MICE Note 226 (more Nov/Dec '08) • Nov/Dec '08 run analyses in progress Jan '08 Jan '08 L. Cremaldi U. Mississippi MICE CM22 RAL Oct 19, 2008

  2. Response to Beam e • Ckova and Ckovb have good • response to =1 electron beam. • Used for =1 gain calibration. • 300 MeV pions will leave 1-2 • PE in Ckova. Can be used for • 1PE determination. • 400 MeV protons below threshold • and can be used for noise level • determination.   380 MeV/c p e   280 MeV/c p Kaplan/Cremaldi MICE CM23 RAL Jan13-16, 2009 -Harbin

  5. T and %RH monitoring • To ensure dry conditions in damp UK weather!  • Temperature and %RH sensors installed + N2 Flow ~ 0.1 SCFH. • One T / %RH set per CKOV. • Readback in control room. • Temperature monitor chips have failed (non-critical). • MOM daily checklist appreciated!

  6. Monitoring and Analysis • Routinely moving MICE files to UMiss for monitoring. • Standard run sheets badly needed with beamline and trigger config. thor:~ cremaldi$ cd MICE_ROOT thor:~/MICE_ROOT cremaldi$ ls 00505.root 00689.root 00850.root 00865.root 00884.root 00506.root 00690.root 00851.root 00866.root 00885.root 00507.root 00784.root 00852.root 00867.root 00886.root 00508.root 00785.root 00853.root 00868.root 00888.root 00509.root 00786.root 00854.root 00869.root 00889.root 00537.root 00787.root 00855.root 00870.root 00892.root 00643.root 00788.root 00856.root 00871.root 00684.root 00789.root 00859.root 00872.root 00686.root 00790.root 00860.root 00882.root 00688.root 00849.root 00864.root 00883.root Dec runs Nov runs Kaplan/Cremaldi MICE CM23 RAL Jan13-16, 2009 -Harbin

  7. LED Pulser Runs – Set 1PE level PULSER ckova ped ckovb fadc DAQ 1pe trig •  Special Pulser runs taken to set 1PE gain. •  Also good for monitoring of PMT drifts. • System needs improvement for non-experts. Kaplan/Cremaldi MICE CM23 RAL Jan13-16, 2009 -Harbin

  8. fADC Ckov Online Monitoring • (max – min) algorithm used by online program for pulse height. • Good for stable signals. PH PH Kaplan/Cremaldi MICE CM23 RAL Jan13-16, 2009 -Harbin

  9. CKOV HV Tuning – MICE note 225 Kaplan/Cremaldi MICE CM23 RAL Jan13-16, 2009 -Harbin

  10. Run 784 300 MeV/c pi+ tof0 trig Kaplan/Cremaldi MICE CM23 RAL Jan13-16, 2009 -Harbin

  11. Run 789 100 MeV/c electrons tof0 trig Kaplan/Cremaldi MICE CM23 RAL Jan13-16, 2009 -Harbin

  12. Run 855 417 MeV/c protons Tof0 trig • Large Ckov signals may indicate some fADC problem? • fADC looks bistable or pions vs protons? JSG? p 

  13. Future plans •  Work on LED Calibration Pulser. • Rework T/%H Monitor. • Install 500 MHz fADC - no shaper needed for higher rates? JSG • More analysis w G4MICE package – tagged beam. • Thank you for your attention! Kaplan/Cremaldi MICE CM23 RAL Jan13-16, 2009 -Harbin
