  • 16.11SCRF ML meetingmonthly

  • 23.11AD&Ibiweekly

  • 30.11(Free slot)monthly

  • 7.12AD&I

  • 14.12…

  • Two meetings per month for AD&I team.

  • TDR related work:

  • design (& cost) work

  • documentation (EDMS)

  • TDR writing (coming soon!)


Today

Today

  • Review DESY BTR meeting summary

    • Sent to AD&I mailing list 01.11.11

  • Action item list (for today)

    • status

  • Agenda for next meeting (23.11)


Baseline decisions

Baseline Decisions

  • Retain a two-stage bunch compressor

  • Reduced field Flux Concentrator for e+ source

  • 500 MV s-band linac for auxiliary positron source

  • Include e+/e- production overhead (margin) in specification for RF

  • HLRF system for 5 GeV Boosters RDR/DRFS

  • Adjustment of the damping ring transfer lines (Central Region)

  • Physics related instrumentation accepted as proposed.

  • BDS/FFS length fixed at current length


Other issues discussed

Other issues discussed

  • Global timing

    • Finalisation of path length for TDR

    • Understand construction tolerance (survey)

    • Location (and design) of adjustment chicane

    • Final path lengths not known until after KEK BTR (Jan 2012).

  • Operations and commissioning

    • Understand strategy and use of beam dumps

      • desired rating etc.

    • Understand scope of use of aux. positron source


Action items 4 11 11

Action Items (4.11.11)

  • Prepare detailed design change document for PLTR, PRTL, ELTR, PRTL

    • Palmer, Paterson

    • Friday 4.11

  • Prepare central region cartoon indicating updated beamline and dump locations

    • Walker, List, Palmer

    • Friday 4.11

Draft document complete 

(Report from Palmer/List)


Action items for today 1

Action Items (for today) #1

  • Update top-level parameters

    • Make Dp/p consistent with two-stage compressor and FC undulator parameters

      • Walker, List, Gai -> try for end of next week!

    • Include shifted waist enhancement in luminosities

      • Walker [Meeting tomorrow with T. Hartin → next week].


Action items for today 2

Action Items (for today) #2

  • Update machine parameters

    • Consolidate/update compressor parameters for two-stage system

      • Solyak

    • Consolidate positron source parameters for 3.2 T Flux Concentrator

      • Gai

    • Update/confirm Damping Ring acceptance parameters

      • Guiducci, Palmer, Gai -> Review Wanming’s design parameters

    • Review and update source RF parameters (gradient etc.)

      • Walker, Gai, Sheppard -> send proposal tomorrow


Action items for today 3

Action Items (for today) #3

  • Lattice design work

    • Propose remaining treaty points:

      • e- ML to e+ source – End of MPS collimator section
