Budget Summary Linac-4 Instrumentation review CERN, 18.10 2011 UliRaichBE/BI
EVM, EDH, budget codes … • EVM: stands for Earned Value Management • The project is subdivided into workpackages • Work package “Beam Instrumentation” has workpackages which correspond to types of sensors: BCT, BPM, SEM … • Progress must be reported each month • Used by the project management to follow progress • EDH: Electronic Document Handling • Contains all orders, workshop jobs … • Budget Codes • Expenditures are assigned to budget lines. The budget codes are “filled” yearly CERN Linac-4 instrumentation review Uli Raich BE/BI
Budget review • At the beginning of the projects non-instrumentation expenditures have been put onto instrumentation budget codes • EVM work packages do not map onto budget codes • One budget code for several instruments (work packages) • Initial budget is assigned to work packages -> Difficult to get an overview -> Go through all EDH orders since 2007 to assign expenditure to correct work package CERN Linac-4 instrumentation review Uli Raich BE/BI

Budget Summary (2) • Emittance Meter oversprends by 80 kCHf(initial estimation 400kCHF for 2 instruments, later corrected to 480 kCHF for 1 ½ instruments • BCTs will overspend by 110 kCHF (390 kCHF -> 600 kCHF) (more different types than initially foreseen) • BPMs will overspend by 200 kCHF (800 kCHF -> 1000 kCHF) • There will be no BTVs but these will be replaced by SEMGrids (which are more expensive) CERN Linac-4 instrumentation review Uli Raich BE/BI
Budget Summary (3) • BLMs: The budget was already been reviewed in March 2011. Very little or no overspending is foreseen • SEMGrids, Wire Scanners and TV screensThe budget was overestimated (fortunately!) • Old electronics used 1 electronics card + 1 cable per channel and the cost estimate was based on this • New electronics uses 1 multi conductor cable + 1 electronics card per sensor plane. Globally: We need to reshuffle budgets internally but should be able to stay within the allocate budgets. We will however also not under spend! CERN Linac-4 instrumentation review Uli Raich BE/BI
