14. DL AP/ASTeC Highlights 1985 Design of the High Brightness Lattice upgrade 1986 Installation of HBL 1987 Resumption of User operations 1988 to 1993 Numerous beam quality initiatives – Replacement and modernisation of all photon and electron beam position monitoring systems – Replacement and modernisation of all steering magnet control systems – Introduction of automated beam position control systems

15. DL AP/ASTeC Highlights 1991 November Installation of the 6T superconducting wiggler 1994 to 1997 Routine high reliability scheduled operations >6000 hours per year Microamp beams commissioned for calibration of astronomical detectors 1995 (Woolfson Report and first work on SINBAD and DIAMOND and the development of the three source scenario for UK SR)

16. DL AP/ASTeC Highlights 1998 Major shutdown for the installation of two 1.4T multipole wigglers requiring the relocation of all 4 RF cavities. 2000 – 2003. After 20 years of storage ring operation, contributed to a number of obsolescence related projects to ensure viability to December 2008. Replacement of storage ring klystron power supply and the liquid helium cryoplant for the two superconducting wigglers

17. DL AP/ASTeC Highlights 2002 Installation of the an new infra red facility and a major new PX facility driven by a state of the art 2.4T mutipole wiggler. 2002. 4GLS through Gateway 1 approval and initial funding of ERLP 2004. Variable polarisation undulator installed – last major upgrade. 2006. 30 stations operational. Start of ramped handover of scientific programme to DIAMOND

21. ASTeC SR Detectors Operations SR Science Engineering SRD Break Up : Mid 2000s RAL Expertise

22. On-going debates on which technical and engineering specialisms should move into ASTeC Ownership and responsibility for equipment and assets Securing agreement on what technical projects should be resourced with 5 years still to run Relative priority of routine maintenance activities Some issues after ASTeC formation

23. Early 2003 : SRD “Wish List” for ASTeC Support (RF and Diagnostics only) – Replacement gun RF amp – Replacement 3GHz generator and amplifier – Replacement RF chopper amplifiers – Replacement booster cavity control circuitry – Digital SR cavity feedback systems – Waveguide and RF load modifications – Procurement of one more high power klystron – Update of all MPW fast interlock systems – Replacement of obsolete components in injector e BPM systems – Upgrade of SR BPM processing to allow msec orbit capture and bulk storage

25. How did we keep going? Sustained high level of professional support Sustained and strong group and individual commitment to the project (especially at times of crisis!) Effective co-operation and communications despite the disruption of management changes Ingenuity and determination (Never say die!) A good sense of humour
