9 Jesus Puerta Pelayo March CMS Week CERTIFICAZIONE DT AGLI ISR fgasparini INFN roma 30/3/2006 The main source of uncertainties is the identification of HV problems (chambers are “new” after HVB replacement). Some of them appear after a long time under HV, some cannot be cured by simple replacement, some are due to single Cells hence very difficult to localize. HV test and Cosmic test must be repeated after any intervention. There are ideas and actions to improve the procedure…………..

20 - Il software generale di simulazione/ricostruzione/analisi di CMS e’ nel mezzo di una fase di transizione al nuovo Framework (CMSSW) Stato del software - Come per gli altri sub-detectors, e’ in corso il “porting” del codice ObjectOriented di simulazione (OSCAR, basato su Geant4) e ricostruzione (ORCA), - il porting delle varie componenti e’ prevista per l’ analisi dei dati del “Magnet test/cosmic challenge” (Maggio-Luglio 2006) U Gasparini [ slides/materiale dal DT sw group: - F.Cavallo (Bologna) - A.Meneguzzo, S.Lacaprara, P.Ronchese, M.Zanetti ( Padova) - N.Amapane, R.Bellan, G.Cerminara (Torino)]

29 Sommario Il Software del DT detector e’ in continuo sviluppo; sostanzialmente “on track” per l’analisi del rivelatore nel test col magnete e l’ integrazione nel sw generale di CSM L’ analisi dei dati del Commissioning delle camere e la ricostruzione (parziale) nei primi test di settore mostrano risultati sulle prestazioni compatibili con le attese e notevoli potenzialita’ per la comprensione dettagliata del comportamento del rivelatore nel suo complesso (utili anche in vista della comprensione del comportamento in campo magnetico, (prima e unica possibilita’durante il Mag.Test.) La preparazione per il Cosmic Challenge e’ a buon punto

They are ready to be used during the Cosmic Challenge The Technical Trigger will be implemented in the Technical Trigger Unit (TTU), housed in the Trigger Crate in Counting Room It will receive the ORs from 1 Barrel Wheel and find cosmic patterns, providing Wheel-level Trigger These features can be exploited by the Trigger Board (Warsaw), loading the cosmic patterns in the Pattern Comparator RBC + TTU
