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, andto 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.

TRIUMF – VECC MoU2TRIUMF – 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.

The Relevance of the VECC The Relevance of the VECC Collaboration 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.

Our goal is to establish a strong graduate student program in Accelerator Physics at TRIUMF in collaboration with Canadian universities.

Towards this goal, for the first time an Accelerator Physics course taught by TRIUMF scientists is offered at UBC and UVic this term: • “Accelerator Physics and Engineering: I. Electrons”

Course material at: http://trshare.triumf.ca/~baartman/PH555/

10 students registered and ~10 audit. Students from UVic, SFU, Cornell participate via video-conferencing.

Process has started to incorporate the course into UBC curriculum.
