1 st day

1st Day

  • Reports from GDE, ILCSC, Physics, RDR, DCB, Regions, and On EDR

  • One IR with push-pull scheme was approved by Physics group,

  • but they want to keep two IR scheme as an alternative

  • From DCB (by W. Bialowons)

    • Cost for super-quads in ML

      • Americas / Europe ~ 2.3 !

    • He said something must be wrong (misunderstanding?)

      • ML area looks having costing from 3 regions. Who made It?

    • He also said “there are more need to be understood in costing”


1 st day cont

1st Day (cont.)

  • on EDR (by B. Foster)

    • Reasonable statement and covered well what needed for the guideline

    • of discussions on EDR

    • He said:

    • need approval from FALC. But FALC will not be ready yet to define

    • EDR they need. So GDE has to assume the level of EDR to get approval.

  • We should learn from XFEL and ITER projects, although EDRs for these

  • projects are very different each other. Very detailed in XFEL and not

  • so detailed in ITER, as ITER had political aspects.

  • PM (Program Manager) is necessary

    • Necessity of PM and PMT was expressed from various groups

    • during the meeting, and Barry said “GDE is looking for PM and

    • PMT candidates. If you have any, please let us know” in his

    • Summary talk on the last day


On edr cont

on EDR (cont.)

  • Work Packages (WP) have to be defined by WP defining group

  • chaired by PM.

    • So, PM will be chosen soon

  • We have to think

    • How to transit from RDR to EDR

    • How to globalize steering of R&D

    • What is the role of PMT in R&D

  • Q: Who organize R&D? GDE or each region?

  • A: Some central control will be the best. How to transit is the

  • question

  • Q: How about the current matrix structure between Area Groups

  • and Technical or Global Groups?

  • A: Obviously not good in EDR. More engineering aspects should

  • be taken into. PMT will think about this.

  • Q: Many PMs are needed

  • A: Yes. Engineers should be involved (Barry)


2 nd day

2nd Day

Reports from RDB all through the day

S0 High gradient 35MV/m

S1 High gradient 31.5MV/m

S2 Linac test facility

S3 Damping Ring (wigglers, kickers)

S4 Beam Delivery System (IR super-Q, super-TFOct,

muon spoilers)

S5 e+ source (undulators)

S6 Control

S7 RF power source


2 nd day cont

2nd Day (cont.)

  • At the time of report on the outline of RDB activities, I pointed out

  • that each technical and global group has their own R&D items. And

  • some of them should not be divided into Areas such as kickers, and

  • survey and alignment technique. There will be such more items.

  • I think this was well understood.

  • On the last day, the survey and alignment group got a chance to give

  • a report on their activities, and recognized as a global group.

    • We should send a recommendation to the RDB on R&D items of

    • magnet system.


3 rd day

3rd Day

  • Parallel session all through the day

    • GDE-CE / DR / ML / BDS+MDI / CFS

  • Main Linac session in the afternoon

    • Session leader, Nikolay Solyak, showed slides sent by

    • John. He also showed a part of these slides on Work

    • Package Items and FTE needed in the summary session

    • on the last day.

    • He also showed the R&D program on quads at FNAL

    • Kiyosumi Tsuchiya showed KEK plan on quadrupole

    • development

    • Installation by Fred Asiri, and CFS by Tom Lakowsky


4 th day summary

4th Day; Summary

  • Each area and CFS group reported the summary of their discussion

    • ML / DR / Sources / BDS / CFS

  • N. Solyak presented a part of John’s slides in the report on ML

  • And M. Ross also presented thought of Magnet and Cryo group

  •  Magnet group’s thought was well understood by attendee

    • But, why Mark? And why only magnet and cryo-group?

  • Summary by B. Foster

    • Level of EDR, 30% or 100%?, will be defined later

      • R. Larsen discussed that the level of EDR would be clear in

      • some sense by defining the construction started two years

      • later after finishing EDR.

    • Necessity of PMand PMT

    • Some parts will be TS WP, such as survey and alignment systems

    • Uniformity across areas is needed

    • Funding will be through each Lab.


4 th day cont

4th Day (cont.)

  • Barry’s summary

    • He said “we will write down the definition of EDR”

    • Goal, getting ready for construction, has to be defined by

    • ourselves

    • Timeframe will be discussed on 8th

    • Will restructure GDE

      • Setting PM office

      • Strengthen system engineering

      • Continuity in Tehch. Sys.

    • On PM

      • More engineering oriented

      • Direct report to GDE head

    • ……………..

  • Should read his summary carefully, and should watch

  • the progress!
