SOMMARIO DT:
HVB e il ritardato avvio di Torino e della produzione dei MC non hanno introdotto
ritardi che si siano ripercossi su sequenza e tempi di installazione.
Tutte le finestre di installazione disponibili sono state utilizzate.
Commissioning e test di settore (vedi Ugo e Marco) senza problemi.
Notevole mobilitazione di personale.
Elementi critici per installazione dopo Mag.Test:
-Certificazione camere agli ISR (dipende da DT)
-Disponibilita’ dei cavi (solo parzialmente dip. da DT)
-Disponbilita’ di personale

CERTIFICAZIONE DT AGLI ISR
Jesus Puerta Pelayo
March CMS Week
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…………..

•

•
YB-1 and YB-2
– Peripheral paths are almost the same as in the positive wheels. No major work is
required there. I can adapt what I already done for positive wheels.
– Radial layouts (ZmL and ZmR) has still to be designed and verified
YB0
– it is not yet defined from the point of view of peripheral paths. D. Dattola is working on
this subject.
– also radial layout ZmL and ZmR are needed
Also there are many other urgent work pending
– Cables in the chains :PRR, procurement, cutting lengths
– cable chain patch panels
– racks layout update (LV/RPC/ALIGN requested changes in the last months)
– Detailed design of each single rack with cables ....

Stato del software
- Il software generale di simulazione/ricostruzione/analisi di CMS e’
nel mezzo di una fase di transizione al nuovo Framework (CMSSW)
- 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)

DT software: Data Quality Monitoring
La parte piu’ avanzata riguarda il DQM degli oggetti di ‘basso
livello’ (raw data/digi), gia’ attualmente inserita nel software generale
e utilizzata nel commissioning delle camere con i cosmici
DT clients for
DQM application
Developed in CMSSW:
- Digi client
- TestPulse client
- Data integrity
Oggetti di
‘alto livello’ (tracce…)per
l’ analisi delle prestazioni
del rivelatore sono tuttora
in costruzione…

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

Technical trigger
Introduction
Goal of this project is to produce
an RPC-based cosmic ray trigger
for the Commissioning of RPCs,
the Cosmic Challenge and later
running of CMS as Technical
Trigger
Local trigger (RBC): based on 1 Sector,
will be used to test RPCs (and DTs)
during Commissioning and Cosmic
Challenge
Global trigger (RBC + TTU): based on
the whole Barrel, will be used during
the off-beam periods for the detector
calibration

Technical trigger
Status
•
The RBC is housed in the Link Board Boxes around the detector and produces 2 Sector Triggers, making
coincidences among OR signals of 96 strips (half RPC) received by the Link Boards
•
3 prototypes of RBC were produced last autumn and recently tested. They are ready to be
used during the Cosmic Challenge
RBC
+ TTU
•
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

Commissioning the gas system at SX5
• Wheels +2 and +1 completed
• Currently working on:
– Flux entire wheels +2 and +1 (need
careful equalization at the channel level)
– Set up of wheel 0 distributor rack
• Check flow cells (found sometimes miscalibrated ,CERN responsibility)
• Sectors under flux (and test) for 3-4
days each
• Monitoring of the gas mixture
• Mass flow-meters read out by ADC + T
and RH probe
• Interface with the HV kill system
