HHH activity/plans in 2006• CARE-HHH coordinators: contributions to

the “Proton Accelerators for the Future” (PAF) CERN Inter-Departmental Working Group, January–March 2006• Preparation of a document for the CERN Council

Strategy Group: Preliminary accelerator plans for maximizing the integrated LHC luminosity, M. Benedikt, R. Garoby, F. Ruggiero, R. Ostojic, W. Scandale, E. Shaposhnikova, and J. Wenninger

• Weekly meetings of the PAF Working Group, intense consultations with several hardware experts and CERN group leaders for a first estimate of future R&D needs in view of the LHC injector complex upgrade

• Discussions with the CERN Director General in view of the open Symposium held in Orsay-Paris on 30 Jan–1 Feb 2006 and in preparation for the Zeuthen workshop of 2–6 May 2006

HHH activity/plans in 2006

• CARE-HHH-APD, February 2006: creation of a first web site with alternative LHC IR optics and agreed criteria for new IR magnet aperture requirements in collaboration with HHH-AMT

• CARE-HHH-APD, March 2006: launching the rating of different LHC IR Upgrade scenarios based on three parameters: • LR: Luminosity Reach, defined as LR=E/Eo where

E is the energy deposition margin in the IR magnets and Eo the energy deposition for nominal LHC luminosity of 1034 cm-2 s-1

• TR&D: the estimated R&D time (in years) needed to develop the most critical hardware (proof of principle) and to integrate it in the LHC

• TOP: the estimated time (in years) needed to experimentally validate an upgrade scheme and implement it in routine accelerator operation


CERNCERN

HHH activity/plans in 2006• CARE-HHH-APD mini-Workshop on Crystal

Channeling, CERN, Geneva, Switzerland, 9–10 March 2006 (attended by about 30 expert)

experimental area Launch of an international collaboration aiming at the preparation

and the running of the H8 experiment Steer a coordinate experimental activity with FNAL on this matter

• Approval by the CERN management of an HHH proposed Crystal Test Facility on a

CERN SPS extracted beam line, in collaboration with INTAS (IHEP, PNPI, JINP) and INFN, with the participation of FNAL

HHH activity/plans in 2006• CARE-HHH-APD CERN-GSI bi-lateral working

meeting on Collective Effects–Coordination of Theory and Experiments, GSI, Darmstadt, Germany, 30–31 March 2006

Topics:• Beam loss and emittance growth caused by

• (1) Space charge and resonance trapping,• (2) Electron cloud and resonance trapping;

• Influence of working point and chromaticity on beam losses;

• Benchmarking of simulation codes & future experiments.

• Impedances - resistive walls and kickers;• Head-tail dynamics and simulation code benchmarking;• Transverse resistive instabilities and other collective

effects;• How does space charge (and electron cloud) affect the

impedance budget in the different CERN and GSI machines?
