7 Full system commissioning Commissioning from chambers up to the Link Boards (1) and commissioning of the full DAQ/Trigger chain (2) are performed in parallel in order to be ready for the full system commissioning. 1.Test and commissioning from chamber to tower : Tower test 2.Commissioning USC electronics: Trigger and DAQ electronics 3.Installation and test of Software: DCS, DSS, central DAQ, Trigger 1.Test and commissioning from chamber to tower : Tower test 2.Commissioning USC electronics: Trigger and DAQ electronics 3.Installation and test of Software: DCS, DSS, central DAQ, Trigger Strong needed of detector/software/trigger expert on site in order to fulfill the tight commissioning schedule. Common efforts of Barrel and Forward communities in order to setup global commissioning procedures.

11 General remarks: There is no doubt that the RPC gas system is complex and it represents one of the key tools for the system operation At the start up some learning period will be necessary to bring the system to a stable state In 2008 low luminosity and “presumably” short running period We have one year work to setup the system and understand operation conditions Combined ATLAS CERN CMS effort Keep level of attention high, but no panic General remarks: There is no doubt that the RPC gas system is complex and it represents one of the key tools for the system operation At the start up some learning period will be necessary to bring the system to a stable state In 2008 low luminosity and “presumably” short running period We have one year work to setup the system and understand operation conditions Combined ATLAS CERN CMS effort Keep level of attention high, but no panic

15 Nel 2006 abbiamo riscontrato tutta una serie di problemi relativi alla lettura della corrente della schede di HV (A3513N) Da qualche giorno la CAEN è riuscita a riprodurre il problema nei suoi laboratori, lasciando le schede accese per una settimana, come da noi suggerito. Ora stanno lavorando alla risoluzione del problema che è sia di tipo software (sincronizzazione) che di tipo hardware (grounding) Entro fine luglio avremo una schema completo dei problemi e delle possibili soluzioni Nel 2006 abbiamo riscontrato tutta una serie di problemi relativi alla lettura della corrente della schede di HV (A3513N) Da qualche giorno la CAEN è riuscita a riprodurre il problema nei suoi laboratori, lasciando le schede accese per una settimana, come da noi suggerito.
