CLOUD Financial Review Committee meeting #3 1 October 2014 Financial plan for 2014 and beyond 1 Oct 2014, indico: rd FRC meeting, Antti Onnela, CERN-PH-DT

One single account in use: CERN Team account T Covers Maintenance and Operation of the CLOUD Facility at the T11 beam- line at CERN o Gas supplies and gas systems o Thermal systems, including temperature measurements o HV system o UV systems o Sampling probes, optical ports o Central DAQ Used also to cover modifications and minor upgrades to the above systems, to adapt them to different CLOUD measurement setups and objectives. As agreed in the previous CLOUD FRC meetings the annual contributions to the Common Fund have been maintained at 50 kEuro and 20 kEuro for category 1 and 2 institutes respectively. 1 Oct 2014, indico: rd FRC meeting, Antti Onnela, CERN-PH-DT2 CLOUD Common Fund

Common Fund budget projections 51 Oct 2014, indico: rd FRC meeting, Antti Onnela, CERN-PH-DT Balance in assumes that all contributions of those years are paid. Notes: 1. No nominal contributions in 2011, only voluntary ones. CLOUD M&O MoU signed in CF budgeted income bases on 50 k€/y & 20 k€/y for cat.1 & 2 partners, respectively. 3. When account balance positive may reduce contributions by factor two to 25 k€/y & 10 k€/y (cat.1 & 2). 4. In 2012 no CF payment by Lisbon, Leeds and Manchester, 10 kE by Vienna, and 30 kE by Karlsruhe. 70 kE extra contribution by Frankfurt to pay CLOUD dewars (of which 44 kCHF N2 dewar included here in income and expenditure, but paid directly from Frankfurt team account). 5. In 2013 no CF payment by Vienna. Lisbon requests 5 kEuro payment. Karlsruhe contributed 20 kE in-kind for permanent SIMONE instrument. Not shown in income nor in expenditure. 6. No CF payment from Frankfurt and IfT until 2013 (BMBF contribution). 7. In 2014 Lisbon requests 5 kEuro payment, Karlsruhe requests passing to cat 2. and 20 kEuro payment. 8. No CF payment from PSI until 2015 (chamber construction debt). PSI contribution in 2015: 42 kEuro, as 8 kEuro to complete the chamber constr debt payment.

Common Fund budget projections 61 Oct 2014, indico: rd FRC meeting, Antti Onnela, CERN-PH-DT Ideal scenario: All contributions paid in time, and the delayed ones in Unacceptable scenario: 100 kE unpaid, every year. Debt paid only by ~2021! Expenditures must stay low (= no major technical problems allowed during 6 years!) Debt paid within Shows that the current Nominal contributions vs. Expenditures is not wrong, if respected by all.

Big accumulated debt: -842’ CHF ≈ 683’000 Euro at end This debt and the unpaid/delayed contributions have seriously compromised the use of the CLOUD Common Fund account in 2014 and getting CLOUD ready for the 2014 run. Positive: Annual expenditures to keep CLOUD operational are going down: A substantial backlog, 260 kEuro, of unpaid contributions [kEuro]: 1 Oct 2014, indico: rd FRC meeting, Antti Onnela, CERN-PH-DT9 Summary of the current status Year [kEuro] (est.)230 (est.)

Expenditures: Budget needed for CLOUD M&O in 2015 is estimated at 230 kEuro. Requesting the FRC to approve this budget. Contributions: CLOUD needs to have a clear plan on covering the expenditures AND reimbursing the debt. Basically, the plan should be simple and inventing nothing new: Every CLOUD partner pays its agreed contributions: 50 kEuro for cat. 1 and 20 kEuro for cat. 2 partners. Backlog of unpaid contributions (total 260 kEuro) paid in Expenditures maintained at the strict necessary to keep CLOUD operational, safe and achieving its scientific goals. Estimated at 230 kEuro / year, for 2015 and  With this plan the debt would be paid within If this plan is not realistic, what needs to be corrected in it? What is an acceptable and achievable reimbursement schedule? 1 Oct 2014, indico: rd FRC meeting, Antti Onnela, CERN-PH-DT and beyond
