Budget Summary

Linac-4 Instrumentation review

CERN, 18.10 2011

Uli Raich BE/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

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

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)

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!
