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

Next Global Runs Tentative schedule

(Acosta/Camporesi, Dec.CMSweek)

“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…

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…?)

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 LUT’s (e.g. to Tracker) for next Global Runs
