Sascha Schmeling & Emmanuel Tsesmelis LHC RRB Scrutiny Group Autumn Meeting August 2009

Introduction  Category C (from experiment M&O MoUs)  General maintenance and operation expenses that are provided to the Collaboration from CERN, acting in its role as Host Laboratory.  Costs are paid by CERN from its operating budget.  Subject to the General Conditions for Experiments Performed at CERN, the Category C headings are listed below:  Safety & radioprotection, INB compliance, radioactive waste disposal, access system, elevators, gerant de site, flood control, insurance (CERN standard), cleaning, office space.  The initial Category C cost estimates for the period were drawn up in 2001 by the then CERN Management.

Report from Meeting with Experiments 21 July 2009  Development of Category C headings  More detailed definitions of the existing headings required.  New headings may need to be incorporated in the list:  e.g. communications (video conferencing), crane & rigging services, doors at experimental areas, transport of material, power  An accord based on either a Service Level Agreement (SLA) or a Memorandum of Understanding (MoU) for the provision of Category C services should be developed and agreed between CERN and the LHC experiments.  The case of ATLAS shall serve as the initial example and which will subsequently be applied to the other experiments.  The Category C cost estimates need to be evaluated and projected for the next 5 years ( ), for example.  All agreements need to be firmly linked to a CERN plan, e.g. the Medium Term Plan, and funds for providing the services need to be fixed.  A procedure for updates of the agreements needs to be found.
