1 Preparazione analisi Global Runs Esperienza dal November Global Run (GREN): ~ 2 settimane di data taking [ => running conditions (non sempre stabili con : DT (whole YB0), RPC (baseline: YB0/+1/+2 Sect4/5/10/11), CSC (YE+2, ME2+ME3) HCAL, ECAL DTTF,CSCF trigger & readout ] Preparazione/schedula prossimi Global runs: - ~fine Febbraio (3 wheels? Alcuni moduli del Tracker?) - Aprile (full Tracker?) - Maggio: CMS chiuso, 4 weeks data taking, B on

2 Next Global Runs Tentative schedule (Acosta/Camporesi, Dec.CMSweek)

3 GREN ~20 M triggers very useful for - syncronization, calibration, alignment - reconstruction optimization: local/global - trigger` studies - correlation between different detectors In generale, e stata una ottima palestra per le DT Alcuni esempi…

4 Synchronization: BX id for HH triggers Triggering Sectors: 3,4,5 & 9, 10,11 Sector 11 Sector 10 Sector 3 Sector 4Sector 5 Sector 9

5 Prompt-Offline time calibration (DT+RPC+HCAL triggers) -MB1 -MB2 -MB3 -MB4

6 Prompt- Local Reconstruction checks: Hit residuals (dominated by uncertainty due to muon time of arrival within the BX window): Run MB1 -MB2 -MB3 -MB4

7 DT in RPC-triggered Events: [ Run ; RPC Triggers in Sectors 9,10,11 & 3) Trigger checks: DT vs RPC

8 Correlation between DTTF & TDC data No bending angle in MB3 Track angleTrack position Trigger position MB1 MB2 MB3 MB4 position plot shifted for MB2 (understood)

9 Global reconstruction Multiplicity of associated hits to global tracks (linking 2 or more stations): Run 30625

10 Global reconstruction Run 30514, ~ 107,000 triggers, ~45 data taking, ~ 40 Hz

11 Extrapolations to calos Run ~20% (~8 Hz) ~40% Extrapolation used in HLT streams

12 DT HCAL correlations Analysis of HCAL-mip triggers using DT tracks, P.De Barbaro et al. Run 30205, 8,000 Hcal mip triggers HCAL Phi tower index HCAL Eta tower index Usage of DT info from other detectors DT Eta tower predictionDT Phi tower prediction

13 GREx- sw documentation …. https: //twiki.cern.ch/twiki/bin/view/CMS/DTanalysisGR GREx documentation (sw, config files, db info…) pages will be regularly linked from the general DT-DPG twiki: https: //twiki.cern.ch/twiki/bin/view/CMS/MuonDPGDT

14 Dati: trasferiti e registrati a Legnaro prompt Calib + reco checks here Output to CMS Orcoff (in a non-authomatized way) Prompt official CAF then Reco, DTEcal/DTHcal streams ect.. to others T1/T2 tiers ~10 h latency Dati analizzabili dal cluster lxcmssrvN (N=4,6) di Padova: working example su : /raid3/share/GRENanalysis/DTAnalyzer_GREN_YB0_Frontier_LNL.cfg

15 Preparazione Global Runs futuri - Utilizzo dati di allineamento (survey + allineamenti interni alle camere) tests sui dati gia esistenti del GREN inserimento in DB ufficiale letto da CMSSW (analogamente a quanto gia fatto per i test pulse di calibrazione temporale) - Studio sui dati esistenti delle estrapolazioni al tracker (rates, possibili selezioni di triggers); studio delle estrapolazioni sopra-sotto; - Essere pronti a inglobare i dati del Tracker nell analisi contatto/collaborazione col gruppo di ricostruzione del Tracker (Patrizia?/ Boris? / altri…?)

16 Alignment checks on GREN data Using data produced from Santander Group (P.Martinez et al.) From commissioning & Quality Control Check data http: //cmsdoc.cern.ch/cms/MUON/ alignment/DTinternal/main.html [ YB0 Sectors: 3, 9, 10 & 11; not all chambers available at moment ] Some **very** preliminary Results (Alicia, U.G.) (next slides)

17 Internal Alignment: Nominal position Using alignment DB MB2 MB1 MB4 MB3 MB4: no correction available GREN Run YB0, Sect 3

18 Internal alignment YB0, Sect 9

19 Internal alignment YB0, Sect 10

20 Internal alignment YB0, Sect 11

21 Checks of survey data: alignm.between chambers - Observed relative mis-alignments between chambers w.r.t. nominal geometry -Correlate with survey measurements (to be done) - Insert data in DB; needed for correct trigger DTTF behaviour as soon as we want to implement pointing LUTs (e.g. to Tracker) for next Global Runs (next slides)

22 Alignment between chambers YB0, all sectors ( GREN Run 30625) : Extrapolations: MB1 MB2 MB1 MB3 MB1 MB4 MB2 MB1

23 Alignment : YB0 Sect 3,4 & 5 Extrapolations: MB1 MB2 MB1 MB3 MB1 MB4 MB2 MB1

24 Alignment : YB0 Sect 9, 10 & 11 Extrapolations: MB1 MB2 MB1 MB3 MB1 MB4 MB2 MB1

25 Confronto dati -MC Muon spectra & mu+/mu- ratio Ripetere le analisi di MTCC (su tutto il detector!)
