  10. ISAC Performance Summary (114)

  11. Highlights of 2008 Campaign FEBIAD ion source combined with high power SiC/Cgraphite target successfully operated at 70 µA protons for TUDA. • Demonstrated high power target operation at full 50 kW proton power (100 µA at 500 MeV). Ex. 11Li. • Development of composite carbide target – allows production of larger variety of intense beams. Ex. 26Al for DRAGON • Development of a new FEBIAD equipped with a cold transfer line for Neon production - reduced isobar contamination.

  17. Expected ISAC Performance

  18. Paradigm Shift in Accelerator Operations An Accelerator Division retreat was held in September 2008 with focus on: Strategy for increased availability of RIBs. Goal: To review and rethink our strategy for maximum scientific output, and to position ourselves for the next 5-year plan. Identified improvements – several already implemented (partial list): • Optimize operations rhythm for RIB delivery - Longer uninterrupted periods of running (no more weekly maintenance) - Shorten target changes => Quick services disconnect • Improved scheduling - Overhead and maintenance identified and scheduled in advance. • Develop a suite of high level applications and add diagnostics to automate ISAC setup and tuning procedures – aim towards a more “deterministic” machine. • Implement a global beam delivery strategy. • Use long shutdowns to schedule stable beam experiments. Changes will result in increased RIB productivity, and allow better management and control of our 5-year plan deliverables.

  19. SRF Developments Bob Laxdal talk • SRF Facility Upgrades • ISAC-II Phase-II Linac • E-linac – VECC Collaboration – Injector Cryomodule

  20. Buffered Chemical Polishing (BCP) Lab Operational • Large fume hood accepts ISAC II quarter wave • cavities, elliptical cavities up to ~1.5 m length. • Six production cavities have been processed.

  21. ISAC-II Phase-II Linac • ISAC-II Phase-II consists of the addition of 20 quarter wave cavities • operating at 141 MHz, β=0.11 housed in 3 cryomodules. • Two prototype cavities tested – exceed specifications. • Six production cavities delivered from local vendor – PAVAC. • Three cryomodules to be assembled, tested, • installed in 2009. • First cryomodule cold test May 2009. • A second Linde 600 W refrigerator has been installed and commissioned. Cold distribution installed now. • Linac installation begins September 2009.

  22. TRIUMF – VECC MoU2 • To advance the E-linac project, expand our SRF expertise and • strengthen international collaborations, an MoU was signed • with VECC in Kolkata in August 2008. • Scope was to design and build Horizontal Test Cryomodule for • e-linac. • After the IPR (September 08) focus shifted towards enabling early high • power beam tests of e-linac modules (JMD suggestion). • As a result, a new MoU is being drafted (nearly complete) to be • signed in May 2009. • Revised scope is to design and build two ICMs, perform beam tests (35 kW) • Director’s VECC Review (November 08) endorsed the plan, • provided advice.

  25. Electron Beam Test Area - 2009-2011

  26. The Relevance of the VECC Collaboration The VECC collaboration is completely aligned and directly contributes to our program: • Allows an early start of the e-linac project. • It is critical to the e-linac project: performing a system integration test with beam, as early as possible (by 2011) will reduce risks associated with the e-linac 5YP deliverable. • It will result in valuable infrastructure and new expertise independently of 5YP funding scenarios. • Advances our core competency in SRF technology. • Introduces TRIUMF to the electron world with potential applications to light sources, and collaborations with electron laboratories. • Can expand to other areas of mutual interest and benefit, incl. student program. A workshop is being planned for 2009 on the long-term vision for our collaboration. NRC International Peer Review
