Draft Budget request is the last year of the Addendum No 3 to the CAST MOU He Running  Shutdown  Data taking – gap settings (resulting from He leaks)  Data taking – high pressure scan towards K Impossible to complete the scan in Preparations for future  Start of some support for design and development towards definition of the next phases of CAST New Addendum ?  Not before late 2011 Must take notice of expenditures in 2011 before new funding agreements start:  Maintenance system Shutdown  Completion of high mass scan ( ~ 140 calendar days) Subject to SPSC/RB approval.  Running of the Collaboration throughout 2011  Support design and development towards definition of the next phases of CAST  Restoring to full operational state – heavily used components of magnet movement system

Details of 2010 : 3He Running January- mid April (eventually started in early May)  Shutdown & Maintenance  Magnet cool, warming passively  5-week maintenance of cryogenics  Inspection 13kA power cables, installation of water leak alarm wires  Modifications and repairs of 3He system  Maintenance of 3He & vacuum systems  Permanent installation of BarBe low-energy axion detector  Electrical noise reduction work on Micromegas detectors  Revision of magnet movement system and electrical noise reduction measures  Sun filming  Magnet electrical insulation tests  Installation of a new system of environmental temperature/pressure/humidity measurements.  Fill the full 3He charge for high pressure running into storage volume May – December 2010  Data taking to fill in the gaps in the scan (consequence of the 3He leaks in 2008)  Cryo problem lost 5 weeks  Data taking – continue scan at high pressures from K towards 120 mbar

2010 Budget request Preparations for next phase  Test lab instrumentation  Magnet design project – support for visitor  Support for work on theoretical estimates – new physics  Design engineer magnet cinematics, new loads for future (Paraphotons, MM heavy shielding) Summary: He running295.2 kCHF Preparations towards next phase CAST62.0 kCHF Table 5: Summary of Draft Budget Request for 2010 See Appendix A 5b for budget estimates

Overall financial situation Expected income for Cat A (type I & II) 2010: [kCHF] Balance (subtracting outstanding commitments) Missing receipts from 2009 (realistic)15.0 (from a total of 52.3kCHF) Promised funds (Add No3)389.4 (294.5k cash k in kind) Total The budget request for Projected balance at the end of 2010 is 250.9kCHF, or about 2/3 of the 2010 budget.  94.9kCHF promised in-kind will not be fully exploited in 2010 ( say 50%)  Cash contributions - uncertainty due to economic down turn and euro-CHF rate (say 50k less?)  In pessimistic projection, + 250k surplus -> +150k at end 2010 The funding for 2010 budget is secure and a healthy surplus is expected for support of the Collaboration in 2011 until a new Addendum is made

Outlook for 2011 Subject to approval ……. Shutdown (starting early for CAST as LHC stops infrastructure) Data taking to complete 3He run  To July 2011 provided Cryo can start in early February Problem with conflict with LHC cryo maintenance work Restore worn systems to working order for any future running of CAST  Aged 13kA power cables to be replaced (50k cables + manpower)  Maintenance electric motors on CAST cryo pumps & magnet movement (15k) Essential mechanical preparation work  Mechanical work on magnet to mount additional detectors (>10k)  Intervention inside cryostat to remove cold windows for future running in vacuum Operational expenses of CAST collaboration – analysis phase Further preparations for future phase(s) of CAST  Theoretical studies  Mechanical design studies  Continuation of the Super-CAST magnet studies  The R&D in detectors Ultra-low background in keV range Low and ultra-low background detectors in the low energy range 2eV-1keV CAST test lab at CERN which will require some more investment.

Appendix A6: Provisional budget estimate for 2011

Financial status 2011? [kCHF] The first provisional estimate for the budget for 2011 is This can be subdivided into: 3He running, completion of scan, 3He data analysis252.2 Preparations for the next phase of CAST (Magnet operation estimate (overpage)) The estimated available funds for 2011 are as follows: Projected balance end Income 2011 (assume 50% of 2010 levels?)195 Total kCHF Provisional estimates for funding and expenditure in 2011 suggest that CAST:  Has sufficient resources to complete the 3He run up to K  Collaboration can continue to function into the final 3He data analysis phase.  Can overhaul the worn-out magnet systems for future running in medium term.  Depending on the size of the 2011 contributions, it could also fund some if not a large part of the design and development work foreseen for the next phase(s) of CAST.  A new funding agreement must be in place before the end of 2011
