4. External & Proximity Cryogenics (AT/ECR)  M&O Work Package CERN-wide operation of cryo-plants and infrastructure will be performed by specialised personnel on duty 24/7. Supervision of cryo-plants of ATLAS/CMS will be made from the CCC and Point 1/Point 5 local control rooms. AT/ECR will provide the required technical support and ATLAS/CMS will cover the financial resources associated with the industrial resources.  Maintenance (manpower and consumables) will be carried-out via CERN-AT industrial contracts.  Experts from AT/ECR will supervise the contract & assist when necessary.  All expenses related to M&O will be charged to ATLAS/CMS.  All non-CERN manpower, consumables, spare parts, cryogenic fluids.

6. Cooling & Ventilation and Power Distribution System (TS/EL, TS/CV) General  Estimates for all experiments for 2005-2010 have been made.  These forecasts shall be used as basis for fixed price to be used.  Fixed price is based on equipment inventory known by the technical service groups concerned.  Details in EDMS 658953 Power Distribution  Fixed price based on existing contracts.  Items not having a unit price (corrective maintenance, AUG tests, piquet) will be charged according to an agreed fixed price shared between LHC experiment and experiments and PS/SPS according to percentage use. Cooling & Ventilation  Fixed price based on existing contracts.  It has been agreed that the LHC experiments will pay 70% of the fixed price corresponding to their share of use.

7. Gas Systems (PH/DT1) M&O for Experiment Gas Systems  Administrative & technical overhead of teams (~1 FTE/year)  General gas support in the assembly and test areas (05-1 FTE/year)  Calibration of Mass Flow Controller.  Cost sharing ALICE/ATLAS/CMS/LHCb in the ratio 23%/30%/25%/22% YearCost (kCHF) 2005160 2006200 2007250 M&O estimates submitted by experiments need to be re-adjusted.

8. Vacuum System (AT/VAC) ALICE (EDMS 703621) and ATLAS (ATC- GE-MA-0012)  Manpower resources from AT/VAC Group and includes the dismounting and re-installation during special access periods when some of the beampipes would need to be dismounted to move detector components.  ALICE and ATLAS will cover the cost of material and participate in the manpower costs.

11. Detector Cooling (TS/CV) M&O of the mechanical, electrical and control components of the detector cooling systems of all LHC experiments (EDMS 688585). Scope  Cooling units/systems for sub-detectors, including evaporative cooling system for ATLAS and TOTEM.  Includes maintenance (preventive/corrective), stand-by duty, assistance in the operation of the systems, fluid & spare parts Limited to the equipment installed by TS/CV.

12. Detector Cooling (TS/CV) Fluids and major spare parts not included M&O estimates submitted by experiments need to be re-adjusted.

13. Magnet Controls (PH/DT1) Work packages for M&O regarding the magnet control systems (MCS) and associated safety systems (MSS) have been agreed. One team of professional technicians will provide an on-call service, preventive & corrective maintenance, modifications and improvements during the operation and testing of the magnets of all LHC experiments.  Result-oriented service contract of typically 6 persons for the 4 experiments. M&O costs to be shared between PH Department (base budget) and by each of the 4 experiments (operations budget). Maintenance of cryogenic systems included in AT/ECR cost estimates.

14. Magnet Controls (PH/DT1) M&O estimates submitted by ALICE/ATLAS/CMS need to be re-adjusted.

15. Power Converters (AB/PO) M&O for spectrometer magnet power converters. Scope  Yearly check-up, minor repairs, calibration and start-up verification.  Does not include: Initial spare parts stock, initial shake-down, significant break-downs.

17. Conclusions Projected M&O costs for technical services have been taken into account by the experiments and, in general, have been correctly budgeted.  Some minor re-adjustments, nevertheless, need to be made to align the experiment budgets to the projections in the Service Agreements. A number of technical services are invoiced on a per-use basis.  e.g. transport & handling, survey, gas consumption
