Content Work Package Definition Construction Program Progress since June 2004 Problem Areas –Update on items from June –Other Points Progress Monitoring Schedule Status Summary

Current Work Packages Approved: –WP’s ATLAS and CMS Gas Systems Defined, but not approved: –WP’s for ALICE, LHCb Gas Systems Not included in our Current Work Plan: –ATLAS ID purge systems –TOTEM (no WP) –LHCb GEM (requirements undefined) Okay ! Design and WP ready next Week (…approval should be done)

Baseline Construction Program 34% 27%21%18% Number of Modules (~ Number of Racks) N.B. Auxiliary systems not included.

Progress since June 2004 (1) Ongoing Construction Work: –Mixer Modules (18 units) (85 % completed) (awaiting decision on pressure regulator). –ATLAS Distribution Racks for TRT and Muons (30 Racks) (30% completed) –Pump Module (14 units) (20% completed) In Preparation (for 2005): –Circ.+Exhaust Modules (14 units), –Humidifier Modules (3 units), –Distribution ALICE and LHCb (~ 17 Racks)

Progress since June (2) Successful Test of full Control System (Pilot System) on the ALICE TPC System. Outsourcing of Production of Control Chassis’s is started. In Preparation: –Pilot Commissioning of Multi Channel System (for end 2005)

Re-Enforcements New Staff: –Two new technicians started this autumn –One Physicist will join end of this year Protvino Team: –Will increase from 3 to 5 persons next in New Laboratory in Bldg. 216 (from beg. 2005) The Pace for the construction will still increase.

Update on Problem Areas (since June 2004) Ageing Risk: ↑ Bottlenecks due to component validation, are getting better, but still problematic ↑ Improved component cleaning from 2005 onwards. Schedules: ↑ Acceleration of construction work ↑ Progress monitoring (presented today) ↔ Anticipate “Engorgement” of activities for Installation and Commissioning ↔ Main commissioning of Closed Loop Circuits in Additional Work: ↑ ATLAS ID Purge Systems designs ready WP can be signed very soon ↔ Test activities, Test beam, etc.

New Cleaning Facility PH – TS collaboration (Joint financing between PH and TS) Installation specially tuned to remove Si pollutants. Intensive studies to find the best machine and the best process. ( done by Cedric Petitjean) Installation can be operational by February N.B. Large parts continue to be cleaned in Prevessin For small parts only (not for pipes)

Problem Areas (2) Manpower –Contract (S 108) transition (-> FSU) makes more administrative work.  From 8 OSVS/year to > 70 Jobs/year  Administrative tools today are insufficient Though, work definition will be better on the long run  For us: difficulties with accounting of FSU work for ATLAS. –Protvino Team will need 2 nd Person with English knowledge when going from 3 to 5. Electrical components for flammable gas systems: –There are new European standards: quite strict and not always appropriate for CERN –Induces extra cost for systems concerned. –But, CERN must allow some exceptions, e.g. MFC’s, Valve positioners + ELMB control chassis -> Inquiry (to PH DL) for derogation is ongoing The exceptions will not compromise the safety They will reduce extra cost and work.

Project Monitoring CostSchedule What ? Material Cost balance Manpower balance How ? Monitor remaining work versus time. Manpower (Updated every 6 months)

Material Cost

Material Cost Balance 42% of budget spent No overall cost overrun !

ATLAS Material Cost RPC: extra humidifier module not in the budget 50 % of budget spent

CMS Material Cost 53% of budget spent

LHCb Material Cost 16% of budget spent

ALICE Material Cost 31% of budget spent

Manpower

> Introduction Type A: Engineering manpower (not considered here) Type B: Construction manpower –Currently we have 8 persons; 7 on construction 1 for management + other activities 5 persons in FSU 3 persons from Protvino (to be increased next year) Monitor: Remaining Work (Estimate) versus Total Work (Budget) Work Done (Measured) - =

(Type B) Manpower Balance FSU activity over last 6 months ATLAS work since last 12 months Status Sept Overruns: ATLAS: Delayed start-up. Mixer Module: Component change. FSU partly backlog from previous contract, help for ATLAS Short-term balance since: Start of FSU (6 months) and since start of Protvino Team (12 months) All in men-months

Full Manpower Balance (type B) 26 % of budget spent All in man-years

FSU 4 FTE/y Type B Manpower versus Time Atlas Protvino 3-5 FTE/y Extra Manpower 1 -3 FTE’s Today

Planned and Remaining Work Type B Manpower Integrated Man-power spent Remaining work Current Estimate Overrun 1.4 m-y Today Budget

Schedule (1) Construction

Schedule (1) We plan to complete >90% of the distribution modules by the end –That should enable the experiments to install UX racks according to their schedule. In 2005 we concentrate on Pump Module, Circ. + Exhaust Module, Humidifier Module (RPC’s). US-installation (Pre-Distribution), remaining Purifiers, Membrane Modules are done > Construction completion of all baseline modules (approved WP’s) will not be before Construction

Construction Schedule

Schedule (2) Installation + Commissioning

Installation Schedule 1.Commissioning schedule of Fixed Piping circuits –Availability of neutral gases in the underground. 2.Schedule of –Detector piping –Chamber connections to pipe work –Installation of plastic pipes (pilot pressures for pneumatic valves (ATLAS)) 3.Schedule for cabling: –Freezing of cable parameters –Cabling installation schedule Our needs from Experiments:

Schedule (2) Installation should be organized by Zones: –UX caverns come first, rack connections of multi channel systems are handled by piping contracts of the experiments. –SG and US areas: we will install complete areas where possible Plan: Start with CMS SG and then Plug Alice –Apart from some exceptions commissioning of closed loop systems will be done in –Flushing of Open circuits can be possible before. Installation If the experiments have priorities please let us know.

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

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

Status Summary Construction ATLAS Distribution going fine. Delivery on schedule, or slightly ahead of schedule. Mixer Modules delayed (by 3 months) due to lacking pressure regulator validation. Pump Module is ongoing fine. Construction will accelerate in 2005 due to new staff, new Lab, etc. Focus on Installation and commissioning: –“pilot” commissioning of Multi-channel system 2005/2006
