TRIUMF U.B.C
Vancouver, Canada

TRIUMF was established in 1968
as a laboratory operated and tobe used jointly by theUniversity of Alberta, Simon
Fraser University, theUniversity of Victoria and theUniversity of British Columbia.
The initial consortium has been
expanded to include theUniversity of Manitoba,
Université de Montréal, theUniversity of Regina and theUniversity of Toronto asassociate members. The facility
is also open to other Canadianas well as foreign users.

TRI-UNIVERSITY MESONFACILITY• Our accelerators arelocated on UBC
campus. It’s abeautiful setting,surrounded by forests,
in the proximity of theocean.

TRIUMF
The world's largest
cyclotron
The giant 500 MeV
TRIUMF cyclotron
accelerates negatively
charged hydrogen ions to75% of the speed of light.
Intense beams of protons
are then directed out of thecyclotron.

Ion Beam
Inside a vacuum chamber (between
the poles of the magnet), a radio
frequency electric field "kicks"(accelerates) the ions twice ineach orbit. This increases boththeir energy and the radius of
their orbit. At the outer edge ofthe cyclotron the electrons are
removed from the ions,
resulting in high-speed protons
emerging from the cyclotron.

PionsBy shooting a proton beam into
various metallic target
materials, a subatomic researchlab like TRIUMF can, every
second, produce billions ofunusual subatomic particles
called pions. Some areelectrically neutral, others carrya negative or a positive charge.
They are all classed as"mesons".

The first model of the TR13,a small, new, TRIUMFdesigned production
cyclotron, wascommissioned in 1995.
This machine yields aproton beam at 13 MeV,
suitable for producing
most of the positronemitting isotopes neededfor PET scans. In tests it
provided more than 60 µA
of beam current
simultaneously to each of
two targets, exceeding its
design parameters.

Isotope Acceleration andSeparation• Astrophysics
A primary objective ofour ISAC Hall facility
is the study ofsubatomic reactions
occurring within stars
during the final stagesof their life cycle.

EPICS Communications• Application Servers andIOCs communicate via
Ethernet using the TCP/IP
and UDP based EPICS
Channel Access (CA)protocol, which
implements a client-servermodel.
• IOCs are CA-servers forthe data they "own", they
may also be CA-clients fordata located in other IOCs.
• Programs running on theapplication servers areCA-clients.

IOCEPICS interfaces to devices
through Input-OutputControllers (IOCs).
At ISAC, an IOC consists ofa VME crate with a CPU(Motorola MV162) andhardware I/O modules.
The CPU is connected tothe ISAC controls ethernet.
