Status / Problems Prospective for 2007 Per Experiment

Gas System Operation for 2007  What can be guaranteed : –We will assure that all 21 LHC gas systems are operating, so that the detectors will be able to take data during the 2007 physics run.  What not: –Gas Analysis items which are included in the WP’s will require manual operation in the beginning. –Some (closed loop) systems may run in Open Mode –Not all Purifiers can be ready. We will provide manual Purifiers where needed. –Membranes (on the critical path). –ALICE TRD not all distribution racks are needed in In general

ALICE  Installation work at P2: –TPC system installation is ongoing (4 months behind schedule). Lot of hiccups and surprises during installation work. Commissioning of full system in August –Mixer and control rack installation in SG is ongoing (finished this summer). –New gas coordinator Antonello Di Mauro very active and present, that helps a lot.  Attention Areas: –TRD distribution on critical path. –TRD Purifier module are on the critical path. Status

ALICE in 2007  TPC (ready, you know…) –Modifications later when TPC moved into UX-Cavern.  Single Pass Systems –Commissioning in August  TOF, TRD commissioning in April –TOF Purifier: temporary installation (cartridges for off-line regeneration) –TRD Purifier on critical path. –TRD Distribution may be done only partly (4/6 racks are not required for 2007).  Some analysis units are delayed, manual use of analyzers will be possible.

ATLAS  ATLAS Distribution units (Muon+TRT (except (CSC)) completed by end of July Other modules (for SG and USA) are also finished or well advanced.  We will start installation work very soon (two persons permanently at P1 from October onwards).  Pilot-Commission ATLAS RPC gas system in Spring 2006 (closed loop).  While installing for the RPC’s system, we try to finish a maximum for all other systems. –Good support from ATLAS  Attention areas: –Membrane module for TRT detector is on the critical path. (see Schedule) Status

We will try to correct over the next 6 months.  Attention areas: –RICH Membrane and Purifier modules on critical path. Status

LHCb in 2007  Muon+GEM: –All modules ready except purifier. –System will run in single path mode in  OT: –All modules ready except purifier. –System will run in single path mode in  RICH 1 –Basic closed loop modules will be installed end of –Purifier: temporary installation (cartridges for off-line regeneration) –Membranes on the critical path –Compression unit done by LHCb (foreseen in WP). –System Commissioning in April  RICH2 –Basic closed loop modules will be installed end of –Purifier on critical path. –Membranes on the critical path –Compression unit done by LHCb (foreseen in WP). –System Commissioning in April 2007.

Schedule (1) Construction

Construction Schedule (compare to Nov. 2004) maintain Delayed + 5 months maintain Shorten -3 months maintain Add TRD Distribution in WU Swap +6 months Swap -6 months maintain New Shifted – 9months

Comments to the Construction Schedule  We need nearly 4 m-y for construction until the end of 2005 in order to maintain the current plan (very challenging !)  TOTEM is not yet included, squeeze in +3 m-m for distribution racks.  Possible Short-Cuts: –TRD distribution make only 2/6 racks (only a fraction of the detector will be installed) –Purifier: make only 2 more (TRD and RICH 2)

Targets for next 6 Months (1) 1.Finnish all distribution units until end 0f Start Pre-Distribution by October 2005, so that we have chance to finish CMS part before April Deliver all gas racks + control chassis for: Mixer, Exhaust and Pump Modules to experimental sites. Construction and Setting up of Modules

Schedule (2) Installation + Commissioning

Installation  Mar has established work plan for the installation in the four experiments.  This plan needs to account for numerous constrains: –Availability of gas system modules –Requirements of individual detectors –Infrastructure and work conditions on the sites. –Limited resources to work on more than 1 site at a time.  Installation work is already on-going, but real increase as of September this year.

Targets for next 12 months (2)  ALICE: (Summer 2005) –Finnish TPC Installation –Connect Mixers in ALICE, install control racks in SG  ATLAS: (Sept. 05 to April 06) –Install in SG (60-80%) –Install in US (60-80%) –Deliver all racks in UX (Pipe connections done by ATLAS and TS) –Install auxiliaries (valve islands, valve controllers, back-up systems, etc.) –Start commissioning of RPC system in April 2006  As of Beginning of 2006, increase manpower further and start working in CMS and LHCb. Installation on Experimental Sites Everything that is needed for 2007.

Proposal Installation Planning (1) ATLAS: UX racks in time in 2005 Main Commiss. in 2007 CMS : UX racks are done Do SG/USC in 2006 RPC Pilot Closed Loop Commissioning

Proposal Installation Planning (2) ALICE: TPC in commis. Aug Single Pass Syst.’s Aug TRD, TOF in 2007 LHCb: Distribution: RICH’s end 2005 Muon and OT early 2006 TRD

Conclusion on the Schedule (1)  The Schedule is very tight, and does not include contingency.  Construction work: –Total Remaining work accounts for 180 m-m, for 2007 we need to do ~ 80 m-m. (50% in 2005, 50% in 2006).  Installation work: –Plan exists (very detailed for next 10 months). –Re-adjustments will be necessary… –Try to meet fixed end dates of Commissioning

Conclusion on the Schedule (2)  Testing and Commissioning: –Huge work in the lab and on site to insure proper functioning of all units. (-> see talk by Stefan)  Commissioning Dates: –ALICE TPC in August 2005 –ATLAS RPC (first multi channel) start in April –Single Pass Commissioning in August –Bulk Commissioning of Closed Loop between Oct. 06 and April 07.

General Conclusions  The gas system construction is on schedule, and on Budget  Though, our plan remains very challenging –We have defined clear targets (for next 6 months and longer term), and we will report every 6 months on the results.  We cannot accept additional work units <2007.  Although, we cannot finish 100% of the gas systems for 2007, we can assure working gas systems for the first physics run in 2007.
