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 ??

Permanent magnets
Typical periods required ~ 20 - 500 mm
Typical fields required ~ 0.5 - 10 T

Cockcroft Research Workshop - Jul04 M W Poole
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
