Andrea Teigelhoefer talk
MISTIC (ECRIS)
 New generation of ECR source, radiation resistant, has been
developed.

Rare Isotope Beam (RIB) Developments
Target Module Upgrade

operation of all 3 ion sources in both East and West target
stations.
=> Increased flexibility, simplified schedule, faster turn-around.
Target Material
 In collaboration with EURISOL, we are developing a high
power Al2O3/Nb target for Ne production.
• The Alumina pellets are brazed onto a Nb foil to ease the
power dissipation.
• This oxide target can operate up to 50 µA proton intensity
at 500 MeV.

Expected ISAC Performance
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.
SRF Developments
1. SRF Facility Upgrades
Bob Laxdal talk
2. ISAC-II Phase-II Linac
3. E-linac – VECC Collaboration – Injector Cryomodule
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.
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.
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.

Electron Beam Test Area - 2009-2011
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.

Graduate Student Program in
Accelerator Physics
 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.
Accelerator Community Service
 TRIUMF organized and hosted:
• LINAC08 Conference – Oct. 08 – 400 participants
• Accelerator Reliability Workshop (ARW) – January
2009 – 90 participants
• PAC09 – May 2009 – 1500 participants expected
 TRIUMF accelerator physicists participate in outreach
activities:
• ILC Accelerator Physics lectures at UVic
• Engineering Physics Project Fair at UBC
