Analysis of HLT Single-Beam Data and Calibration Issues - Run 89293

This report outlines the findings from the analysis of single-beam data from Run 89293, focusing on the HLT (High-Level Trigger) running offline and various issues encountered. It highlights discrepancies in energy calibration, particularly in the LAr gain factor and timing synchronization. Observations include spikes in the eta distribution and challenges in processing ESD files. The report emphasizes the need for further investigation and collaboration among on-call shifts to resolve ongoing issues and improve trigger operations.

  1. e/gamma report Ricardo Gonçalo for the e/γ slice

  2. Single beam Danilo Ferreira • Run 87764 • Single-beam • HLT run offline • EDM seems ok from HLT running offline • Except for ID-related objects • Chains don’t get there? • A lot more clusters with eta < 0 for EFCalo than for T2Calo • EF energy completely off • Wrong LAr gain factor? • Last minute: • This may be caused by wrong timing and missing conditions for parts of Lar • Some of it solved since then, but offline need one preliminary iteration to synchronise digits Trigger Operations - 18/9/2008

  3. Eta and phi • Spikes at L2 • eta≈-1.3; phi≈-2.1 • Very odd EF eta distribution Trigger Operations - 18/9/2008

  5. HLT running algorithms online! Ricardo Gonçalo • Run 89293 • SingleBeam_v1 HLT menu running online on cosmics Trigger Operations - 18/9/2008

Trigger Operations - 18/9/2008

  7. Other issues • Problems trying to run on ESDs from run 89293 (used ATLAS-GEO-03-00-00) • Couldn’t find trigger configuration in ESD file • IOVDbSvc errors • Stefan Ask sees same problem (in up-to-date code) • Current chains: • “normal” e5 chains starting from EM3; separate chains for IDScan, SiTrack, FwdBckdTracking, TRTxK • Calibration chain: g10 • New chains starting from MBTS+BPTX: g0_mbts_a/c • ABORT_CHAIN: • Throws events to DEBUG stream (exclusive! Events lost from “physics”) • T2CaloEgamma now returns HLT::ErrorCode(CONTINUE, USERDEFS_2) • To avoid debug stream; but creates warnings! (NOTE: trigger shifter should see warnings) • Other ABORT_CHAIN still exist in chains • Would be useful to have list of files with event ranges in interesting runs page Trigger Operations - 18/9/2008

  8. Conclusions LOTS of work is needed!! • People in e/gamma on-call shifts • Denis Damazio • DaniloFerreira de Lima • Ricardo Goncalo • Phillip Urquijo • Andrew Hamilton • Monika Wielers Trigger Operations - 18/9/2008
