LS1 DayEN-CV M. Nonis on behalf of CV group/ CERN - 12.06.2012
Contents • Introduction • Projects for LS1 • PS and Meyrin site • LHC and Experiments • SPS • North Area • Overview on maintenance • Operation 2 M. Nonis - LS1 Day - 12.06.2012
Preamble I n t r o d u c t i o n The object of this presentation is to show what will be done by CV Group during LS1 with respect to the requests received and consolidation needs; the focus is made mainly in the projects that cannot be performed during LS1. In addition, some activities (projects, maintenance) that have a major impact in the availability of circuits will be mentioned in order to allow everyone to have the full picture of the constraints to face in LS1. The presentation is divided in geographical zones, almost corresponding to the different machines complex. In this talk we take into account requests created in Plan.cernuntil Wednesday 5th June; later ones are not included and not accepted at today. 3 M. Nonis - LS1 Day - 12.06.2012
Terms and Definitions I n t r o d u c t i o n When is LS1 for CV? In order to be able to allow the cool down of LHC and the powering tests, the LS1 for CV Group is from January to December 2013. We are requested that in 2014, all plants linked to the run of any accelerator shall be operational, only maintenance work will be allowed in view to minimize the time without maintenance until December 2015. 4 M. Nonis - LS1 Day - 12.06.2012
General overview of CV Activities I n t r o d u c t i o n * Base 2012: 71’000 hours Activities confirmed for 2013 (CV LS1) 91 60% Activities that will start in 2014 14 10% Activities postponed after 2014 23 15% Pending requests 24 15% 49% of request not declared before end May 5
Other figures • New major supply & installation contracts: 26 • Massive use of existing contracts: > 50 orders • Number of additional contractors’ staff depends on final dates of maintenance interventions but it can’t be considered unlimited (supervision work for CERN, need to know circuits before working on them).
General Organization CV I n t r o d u c t i o n • External help from INFN for engineering activities? • Ok on some projects – not on any • Time is (almost) late, decision is more than urgent. • During LS1 all possible resources will be moved from operation activity to work supervision. • However, the maintenance workload will increase. • Operation requests: most of the dates are not defined so that we cannot confirm whether they can be satisfied according to installation availability, or if they cumulate at the same period and represent a too high workload. • It will not be possible to cumulate the workload for projects and maintenance (and operation) in the same period, therefore maintenance work must be distributed all along the 12 months of 2013. This implies that maintenance will not be limited to the very first few months of 2013. M. Nonis - LS1 Day - 12.06.2012 7
Simplified Scheme CV Cooling Circuit I n t r o d u c t i o n Demin. Water make up from bldg 378 M. Nonis - LS1 Day - 12.06.2012 8
Test & Commissioning I n t r o d u c t i o n Given the quantity of CV systems concerned and the important modifications to be performed, the test & commissioning of each CV plant will be a major activity requiring several days per plant. In addition, each equipment Group will need to test & commission his equipment before considering his work completed. During each of these steps the effort required to CV team is not negligible (drain, fill up, balancing of circuits…) and, only after their successful completion, CERN can enter the commissioning phase of each accelerator. I am convinced that all this should not be under evaluated. 9 M. Nonis - LS1 Day - 12.06.2012
Meyrin - PS Projects in LS1 nTOF FAIR ISOLDE ELENA PSB L4 Done in LS1 Not done in LS1 10 M. Nonis - LS1 Day - 12.06.2012
LINAC 4 Projects in LS1 • HVAC plant is completed July 2012 • Cooling plant is completed September 2012 The decision of delaying the commissioning phase of L4 of 1 year does not have an effect on the CV installation work; however it will avoid clashes between operational needs for L4 and CV maintenance/project work during 2013. 11 M. Nonis - LS1 Day - 12.06.2012
ISOLDE HVAC COOLING Projects in LS1 building 197 • Ventilation – Sept 12 to Febr 13: • Bldg 170, 199, 198 • Faraday cage • Cryo cold box • Air conditioning Labo class C bldg 115 Refurbishment existing station (open loop): no cooling possible until June 2013 • Cooling – Dec 12 to May 13: • 1 circuit for existing + extension, 27-37°C • 1 circuit for BTY magnets (RP safety), 27-37°C • 1 circuit for RF cavities, 20-30°C (primary: chilled water) 12
Other ISOLDE activities Projects in LS1 CV work (design and installation)linked to the following requests: • New ventilation for the extension of storage for target area • ISOLDE robot installation • Hot cell installation • Integration of Rabit in the ventilation system to be moved during 2014 or later if not compatible with beam program. 13 M.

CV Installations’ Availability – Any Complex Maintenance M. Nonis - LS1 Day - 12.06.2012 35
Maintenance Planning for LHC Experiments Maintenance • ATLAS: June to September 2013 • ALICE: June to September 2013 • CMS: November 2012 to January 2013 • LHCb: January to April 2013 M. Nonis - LS1 Day - 12.06.2012
Functional Tests Maintenance • CV needs to perform functional tests in order to ensure the functionality of the installations during operation: • Safety tests or back up; • Valves manipulation (e.g: in concrete floor); • Degraded mode scenario (ventilation systems); • During maintenance and tests, the availability of CV services shall be affected and/or stopped. • Estimated 1-2 days per Point 37 M.

Requests for operation of cv systemsin 2013 M. Nonis - LS1 Day - 12.06.2012 38
CV Services Available during LS1 Operation • CV will ensure only essential services: • Ventilation of underground and surface premises (tunnel, experimental areas, buildings…) but not the ones dedicated to specific equipment. • Chilled water only for ventilation purposes • Compressed air • Raising systems • Drinking water supplies • Fire hydrants network • Temporary stop of these installations might take place according to modification work or maintenance interventions to be performed. 39 M. Nonis - LS1 Day - 12.06.2012
Operation 2013 Operation Requests received have not enough details: “need water for 130 weeks from December 2012”. Received requests (full list): • PS • LINAC 2, 3 and 4 • CTF3 • Cloud • ISR area • AD • RF (mainly SPS) • CAST • CMS, LHCb These requests can be satisfied provided that they do not clash with the planning for projects and maintenance. Requests 2014 are ok: maintenance interventions will be adapted accordingly. 40 M. Nonis - LS1 Day - 12.06.2012
Conclusions Still lot of details have to be defined. Present situation is tight but CV is confident we can succeed. What we do not know is whether the picture we have is complete or someone has still to show up and formulate additional requests. This is the most sensible and urgent point: CV has to evaluate, launch or complete the studies now, there is no possibility to change direction in a few weeks. 41 M. Nonis - LS1 Day - 12.06.2012
