Treaty Points and Costing Guidance

1. Treaty Points andCosting Guidance Nick Walker1st System Area Managers Meeting KEK – 19.01.2006

2. Introduction • Review the system boundaries outlined in this document • Iterate and discuss • agree on boundaries • Discuss costing guidelines

3. The Baseline Machine (500GeV) ~30 km ML ~10km (G = 31.5MV/m) 20mr RTML ~1.6km 2mr BDS 5km e+ undulator @ 150 GeV (~1.2km) x2 R = 955m E = 5 GeV not to scale

4. RDR Matrix

5. RDR Matrix System Areas Geographical breakdown of machine Primary responsibility for design and ‘ownership of costs’

6. RDR Matrix Technical Systems Your ‘Engineering & Cost’ resources Responsible for engineering designing and costing of components in area systems A point of contact will be identified for each tech. area to each system area

7. RDR Matrix Global Systems Responsible for the more global aspects of the machine which do not specifically relate to a single system area or technical group

8. RDR Matrix Reloaded System Areas design iteration cost push-back optimisation ‘overhead, contingency & redundancy’ checks costs costs Tech. Groups Global Groups costs

9. Boundaries (Treaty Points) • e- source • e+ source • DR • RTML • Main Linac • BDS

10. Boundaries (Treaty Points) • e- source • e+ source • DR • RTML • Main Linac • BDS Polarised electron gun (including laser system) capture/bunching system/pre-acceleration acceleration to 5 GeV spin rotation collimation up to (but not including) DR injection e- gun on positron system also included(up to dipole before 5 GeV linac)

11. Boundaries (Treaty Points) • e- source • e+ source • DR • RTML • Main Linac • BDS All beamline components integrated with main ring vacuum system Associated ancillary systems (power supplies, RF, etc.) For stacked e+ ring, includes bunch combining/separation systems

12. Boundaries (Treaty Points) • e- source • e+ source • DR • RTML • Main Linac • BDS Begins after DR extraction system and compensating bends Ends at entrance to first Main Linac cryomodule

13. Boundaries (Treaty Points) • e- source • e+ source • DR • RTML • Main Linac • BDS Begins with first cryomodule after RTML Ends with last cryomodule before BDS In addition to basic RF units, includes any warm insertions (diagnostics stations, MPS systems etc.) problem area: e+ source in e- linac

14. Boundaries (Treaty Points) • e- source • e+ source • DR • RTML • Main Linac • BDS Begins at exit of last cryomodule in Main Linac Ends at (and includes) main beam dumps

15. Boundaries (Treaty Points) • Target system • dump • Capture system • pre-acceleration • (long) transfer line • 5 GeV injection linac • up to DR injection • undulator system • e- bypass system • pre-undulator • collimation (MPS) • pre-undulator FEX (MPS) • e- source • e+ source • DR • RTML • Main Linac • BDS clear responsibility of e+ source group could be considered part of ML

16. Costing Guidelines • The RDR is • not a complete Technical/Engineering Design • a design made to the level required to support a reliable cost estimate • Good common sense has to be applied to level of engineering/costing • Main Linac, CF&S • cost drivers: pay attention to details • Injectors, DRs, BDS • not cost drivers: can make looser cost estimates

17. Example: US study note: US accounting full-cost model CF&S included for each system

18. Example: US study note: US accounting full-cost model CF&S included for each system Orthogonal view (technical groups)

19. Cost Drivers: SCRF tech. • bottom-up cost detailed cost estimate based on • existing information (TDR, USLCOS) • new input from industrial studies (US?) • (XFEL TDR cost update) • May have largest uncertainty • International agreed upon model for costing SCRF tech. needed

20. Cost Drivers: CF&S • Civil engineering requirements must be well specified • tunnel diameters, lengths • # of shafts, access etc • PPS zones • shielding requirements for hi rad areas etc. • surface building requirements (space!) • scaling from existing machines or similar engineering projects useful • site dependencies may exist • Must have a clear picture of what you want to go into a tunnel, shaft, hall or building

21. Cost Drivers: CF&S • Cooling & AC power requirements • input needed from AS on • magnets, power supplies, electronic racks, klystrons/modulators etc. • some can be scaled from existing infrastructures • Special case: cryogenics • look to LHC…

22. Non Cost Drivers • Careful: taken together still ¼-1/3 of total cost • magnets: rough estimates of IV parameters, cooling requirements needed based on field specs from AS • No need to perform detailed magnet design • ~30% best guess  ~2% TPC • (warm) vacuum systems: • rough design; scale from existing machines • controls (inc. software), instrumentation… • rough counts, scale from existing experience

23. An Example: example taken from USLCOS

24. WBS [PBS?] • WBS is needed to define the level of cost detail required • First-pass at WBS (level of detail) can be made from experience • Will need to iterate as costs begin to arrive • Our first job! Define the WBS

25. WBS using SLAC tool
