UK funding for accelerator science for particle physics 2004 - 2007

• UK funding agency, PPARC, secured from Govt. £11M for ‘accelerator science’ for particle physics, spend period April 04 – March 07

• Called for bids from universities and national labs; large consortia were explicitly encouraged

• 5 bids received: A total in excess of over £24M was requested!

4. Final-focus Luminosity Stabilisation(QMUL, Oxford, Daresbury)

• Beam-based feedback:

Worked primarily on intra-train FB as complement to

‘IP FB’ (train-train) + active mech. stabilisation schemes

(warm design)

• Simulated intra-train FB for J/NLC, TESLA, CLIC

Location of

FB BPM:

Integration of Stabilisation and Feedbacks

Timescales/frequencies:Survey + alignment: year (complete), weeks (local)Beam-based alignment: weeks – days Slow-orbit beam feedbacks: hours – minutesActive stabilisation schemes: seconds – millisecondsPulse-pulse beam feedbacks: millisecondsIntra-train beam feedbacks: microseconds (TESLA) nanoseconds (J/NLC, CLIC)

Need to understand, through performance simulation, hand-overbetween these systems: avoid: feedback ‘competition’ frequency ‘shuffling’

Summary and Outlook

• Embarked on a substantial UK LC BDS work programme

• Have expertise in some areas, learning in many others

• Aiming to build a strong, coherent design team:

intellectually interested in BDS

aim to be major player in Global Design Office (start 2005)

aim to prepare UK funding agencies for a UK LC contribution

• Collaborating w. European partners via ‘Framework 6’ programme:

EU funded LC ‘network’ to facilitate interactions

Drafting ‘design study’ proposal for LC design work
