Firm. Ware The version 0 x 590 has found issues for events in the Orbit gap – wrong handling of Idle words Firmware is rolled back to the older version for HF and a corrected version 0 x 690 is deployed for HB/HE/HO This corrected version is found to be working satisfactorily. Pedestal subtracted Rec. Hit distribution for abort gap pedestals look healthy (no tail on +ve side) Thanks to all who found the problem and solved it within time constraint March 28, 2012 2
LUT Finally a version of LUT is created with latest tags from Channel status Pedestals Gains Response corrections It is validated and tag given to L 1 trigger group to be used for data taking The exercise showed that documentation needs some improvement Run emulator code only on NZS data Do not generate LUT’s while running on the data Thanks to all who could make it happen March 28, 2012 3
ROBox recalibration/LUT regeneration Recalibration started with iterative and NZS methods (Igor/Olga). Combined tag with coefficients was added as IOV to the Resp Corrections tag for LUT regeneration by Zhen Pablo started LUT generation/Validation We assume new LUTs to be uploaded at the beginning of the next week (probably, Monday) March 28, 2012 4
Plan for 2012 calibration Regular HPD/PMT gain updates with LED Study the possibility to introduce raddam corrections Phi-symmetry monitoring/re-calibration Absolute scale monitoring/re-calibration with isolated tracks and Z->ee. Possible problem in HF with re-calibration of short fibers in the presence of the radiation damages (need studies) Introduce Z->ee HF scale in MC March 28, 2012 5
Pledges A lot of institutions pledged but Still under pledged CMS software, Detector performance and databases In Database we do not have pledges of Umesh/Zhen/Valdas !!! March 28, 2012 6
Misc. HCAL News HPD’s in rings ± 2 are switched on – this results a change in Channel. Status record. HO will be used in Particle. Flow and will impact the general Reco schemes The tight reconstruction window is cutting into time/energy distribution for laser run events Change configuration for reconstructing laser events? Pledge period is extended till April 15. Several critical laboratories have not filled in the ESP table yet. Please urge all group leaders to take care of the ESP table. March 28, 2012 7
