## Closing RemarksSteve Peggs

- Mirrors:  http://www.rhichome.bnl.gov/LARP    http://www-td.fnal.gov/LHC/USLARP.html

## Commissioning

- We propose adding a 3rd commissioning task, “LHC Hardware Commissioning”, if financially viable (must seek additional funds)
- BNL and FNAL directorates have already expressed unambiguous support for such a LARP task
- When Roberto’s 40/140 report is ready, we go to the 4 U.S. lab directorates and DoE with a broad commissioning proposal
- Where are the engineers - BD, TD, C-AD, .... ?
- As with Beam Commissioning, we must name names ...
- ... in a systematic & impartial fashion that respects individual privacy

## Interaction Region Upgrade

- Quad or Dipole first?  Large crossing angles with superbunches or crab cavities?
**“****The choice of the coil aperture is driven more the power density limit than by the beam acceptance”**  (Ruggiero et al)
- “An estimate of the radiation parameters of the magnets requires extensive simulations based on detailed knowledge” (Ruggiero et al)
- Launch an integrated analysis of a “strawman” quad first layout ??
- 		sample optics, apertures, energy deposition (liners etc?)
- 		quench analysis, component survival?
-  		heat removal analysis
- 		iterate?
**Realtionship with CARE?**

## Calendar/milestones

- Nov	  8-11	CARE "Beam Dynamics in Future Hadron Colliders .."
- Dec    15	(Magnet) Task Sheets & milestones deadline
- Dec	  15	Quarterly Report deadline
- Dec	  31	Abort Gap Monitor engineering feasibility study white paper
- Dec		??	Dipole Design Feasibility review, BNL
**2005**
- Jan 		??	Tune Feedback workshop, BNL (2 days)
- Jan	  31	Define LARP Beam Comm/LHCOP integrated plan
- Mar	 	??	Lumi & TF Technical and Cost reviews, BNL
- Mar	  8-10	**LARP collaboration meeting 4, (Geneva/Aurora/Lake G.)**
- If/when ?	“Going long” workshop?

## Collaboration meeting 4

- Feedback, please:
- 2.5 days is correct length (Tues -> Thurs)
- 0.5 day plenary at each end
- Parallel/series
-     Accelerator Systems folk meet in 3 parallel sessions
- 	1) Instrumentation, 2) Collimat., 3) Acc Phys & Comm
-     Magnet folk meet in a single session
- More discussion, fewer presentations?
- How to eschew “survey” reports?

## Web & publications

- Establish key papers, and links to papers, on mirrored web sites
- Internal technical note series on web page
- No format rules beyond “PDF”
- “No” editorial review
- External paper rules?  PAC05 abstracts in by December ...
- Web site contributions and comments, please, to me
- 	“All” contributions and most comments accepted verbatim
- 6)	Post the LARP program (task sheets, milestones, ...) publicly

- Mirrors:
- http://www.rhichome.bnl.gov/LARP
- http://www-td.fnal.gov/LHC/USLARP.html      (name change?)

## New Task Proposals

- New Task proposals, eg
- 	AC Dipole, Schottky monitor, Wire Beam-beam
- 	Many magnet program tasks
- Yes, need a semi-formal procedure to vet them ....
- 	US lab protagonist required for each task (AC dipole ?)
- 	Tasks should involve more than 1 U.S. lab (in general)
- 	Bi-lateralism may be appropriate (case-by-case)
- Door must be seen to be open to new tasks
- Accelerator Systems:
- 	as old tasks roll-off, new tasks roll-on?
- Prioritization with limited funds ...

## Accelerator Systems, other

- 1) 	Re-evaluate milestones, remove question marks on calendar
- 2) 	Chart a road map for IR layout resolution (CARE)
- 3)	Field Control Room?

## Summary – Superconducting Magnets

- 1) We are arriving at a mature and unified program!
- 2) Final task sheets and milestones by Dec 15, please
- 3) “Level 2 co-ordinators” – have org chart, will travel
- 4) Ad hoc mechanisms for collaborative technical decisions
- 5) Can long magnets be built?
- Will they quench (8 kW)?  Can the heat be removed (at all/economically)?  Will they survive eg 7 years?
- 6) Diversity maintained (judiciously)
- Racetrack coils/magnets, bladder & key, open mid-plane dipoles, R&W, ..

## Summary - Miscellaneous

- “Outreach” to our own communities – ATLAS, CMS, ILC, ...
- 	NOT a light switch: 350 MJ, snap-back, magnet physics, ..
- 	Accelerator Technology is ONE, across hadrons & leptons
- 	Train young people
- Unresolved: how does the LARP collaboration produce high profile technical papers, eg PAC05 & MT-19?
- Standing Monday Video Conference (BNL/FNAL/LBNL) is available ...
