Accelerators at CCLRC - Lancaster University · 2004. 8. 10. · Cockcroft Research Workshop - Jul04 M W Poole CCLRC Accelerator Organisation • Accelerator Science and Technology

Cockcroft Research Workshop - Jul04 M W Poole

Accelerators at CCLRC• DL and RAL created as particle physics laboratories

• 40+ years expertise in electron and proton accelerators

• Design, build and operate Large User Facilities• latterly photon and neutron sources: SRS + ISIS (+HELIOS)

• Develop next generation solutions• DIAMOND, ESS, 4GLS, …….

• Underpinning R&D programmes


CCLRC Accelerator Organisation• Accelerator Science and Technology Centre (ASTeC) created

in 2001. Now 40 staff - accelerator specialists only

• Autonomous Centre within CCLRC (Oversight Boards)

• Infrastructure largely inherited - needs upgrades

• Major expansion underway - ~£4-5M pa programmeFunding mainly from CCLRC + PPARC

• Major development activity also in ISIS Department at RAL• plus other small activities (eg SNP …)


ASTeC Structure

Five Groups:

– Accelerator Physics (Susan Smith)– RF and Diagnostics* (Mike Dykes)– Insertion Devices & Magnets (Jim Clarke)– Vacuum Science* (Ron Reid)– Intense Beams (Chris Prior, RAL)

Recall ASTeC utilises other CCLRC technical resourceseg engineering, controls, ...

* See talks later


ASTeC Strategic Objectives• Establish and consolidate UK core accelerator skills base

– leadership

• Ensure international competitiveness – people + programme

• Develop future LSF – advice, design, prototype, construction

• Promote suitable CCLRC activities

• Pursue underpinning technology – inc. experiments

• Encourage collaborations – HEIs + international

• RF technology

• Beam dynamics codes etc


EU Programmes

• Existing FP5 ones in place EUFELE RF Cavity (X)

• FP6 I3 contracts: HIPPI ELAN (PHIN)

• FP6 successful bids: LC FEL

NB Major problem of overhead recovery


Expanded Resources 04/05

• Injection of SR02 CCLRC funds - £1.32M (focus on 4 lines)

• Injection of SR02 PPARC funds - £1.35M (6 new posts)

• Uplift existing programmes

• Total CCLRC Direct Vote programme = £3.3M

NB ASTeC also supports DLS (4), SRS (6), 4GLS (8.5)

CCLRC Role in DIAMOND• Daresbury (ASTeC et al) produced Conceptual Design (1993)

• CCLRC generated detailed Design Specification (2002)

• CCLRC continues support (40 FTE in 2003/04) to DLS Ltd with both design and procurement assistance

• ASTeC supplied 10 FTE (in 2003/04) (including 3 Group Leaders)

• Support now reducing greatly (4 FTE ASTeC)

• DIAMOND commissioning support ??


Insertion Device Technologies

Electromagnets

Superconducting magnets

Permanent magnets

Typical periods required ~ 20 - 500 mm

Typical fields required ~ 0.5 - 10 T

See talk by Duncan Scott later


New Generation Light Source• Strong UK communities exploiting existing advanced storage

ring and ‘table top’ laser facilities (SRS, ESRF, CLF)

• DIAMOND will serve the x-ray community from 2007 (XFEL ?)

• Low energy (< 100 eV) requires a separately optimised source

• Users have identified the need to supplement transverse brightness by compression longitudinally - fs pulses

• Many scientific applications need multiple sources– eg pump-probe

PPARC Funds for CCLRC (3 years)

• Total funds £4.5M (75% LC, 25% NF)

• Staff support £3M (ie ~40 sy)

• ASTeC gets £2.4M to cover staff

• This covers both LC and NF activities

• SLA about to be signed with CCLRC (ASTeC)


TESLA Linear Collider Scheme

TeV centre of mass


LC-ABD Collaboration

• Linear Collider studies now organised in UK largely through LC-ABD Collaboration with HEIs

• Strategic decision to concentrate on Beam Delivery System

• Major PPARC funding initiatives (ca £10M next 3 years)

• ASTeC takes lead in Beam Dynamics and in Magnet and RF Technology

• Further major ASTeC role in Beam Diagnostics


LC Work at ASTeC

• Beam dynamics* (ASTeC team formed)

• Polarised positron source (undulator)

• Crab cavities

• Diagnostics

* see talk later by Deepa Angal-Kalinin


ASTeC Funded LC ProgrammeExtrapolated SR02 funds from OST = £6M over next 3 years

Policy directives:• 25% on LC programme: £1.5M• £500k to be available directly to promote HEI studies• LC-ABD support must be demonstrated• Priority to synergetic activities (eg Light Sources)

Decisions on work packages:– Collimation– Longitudinal bunch diagnostics– BPM R&D


ASTeC Funded Collaboration Packages (3 year)

1. Collimation (ASTeC/Lancaster)• wake field simulations + possible experiments• £500k (inc RA)

2. Temporal Profile (ASTeC/Abertay)• electro-optic developments (+ small SP support)• ultrafast laser for tests• £600k (inc RA)

3. Advanced BPMs (ASTeC/Cambridge/UCL)• use in high precision spectrometry• £250k (inc RA)

NB CCLRC will also fund international advisory panel


Issues for ASTeC• Establish strategic baseline funding

• Recognise need for ASTeC infrastructure - and invest

• Progress Cockcroft/ASTeC

• Establish detailed case for SRF investment (NWSF bid)

• SR04 bid made for ATF at Daresbury

• Caution on FP6 initiatives


Possible New Collaborative Research Topics• Advanced beam dynamics

• FEL Studies (inc XFEL)

• FFAG (inc electron model)

• High brightness electron beam test bed

• SRF systems

• Broader LC R&D (eg CLIC, damping rings, ..)

• Laser wakefield R&D

• Proton beam projects (eg driver, muon systems, …)

• Existing small scale ASTeC/CCLRC programme

• Major expansion includes PPARC £1M boost (3 years)

• IB Group funded for NF conceptual studies (~£400k)

• MICE may be approved soon ? (£12.5M UK support)
