Type of Action:


Add new graduate course


Rat
ionale:


Accelerator Physics has long been offered
as an area of research for graduate students
in the Department of Physics and
Astronomy, but course offerings have
typically been once every few years,
offered as a Directed Studies special topic
course (
it is currently offered as PHYS
555B 207
). With the recent expansion

of
TRIU
MF’s
Accelerator P
hysics
r
esearch
program,
and plans to construct a
superconducting electron accelerator,
a
graduate course in Accelerator Physics
should be formalized
.

orting documentation:


Course Learning Objectives:

This 3
-
credit graduate level course, which is offered in collaboration with TRIUMF,
starts with a general

introdu
ction of
various types of particle accelerators and applications
and the fundamentals of
accelerator physics. The course then focuses on electron
accelerators,
including

principles

and
technologies associated with

the generation and

acceleration of electron beams
,
b
eam dynamics, and

applications of electron accelerators
in high energy and nucl
ear physics and as
synchrotron radiation
sources.



The course will be of interest to any student with a suitable background in Physics,
Engineering Physics, or Electrical Engineering and who is


interested in use of particle
beams for basic research or
applications.

important role in training the next generation of accelerator scientist
s and engineers.
Presently there are only a handful of universities in North America offering graduate
courses and research opportunities in accelerator physics
.


UBC graduate students
would

uniquely
benefit
from

the
research opportunities
in
accelerators

offered
by

TRIUMF,
utilizing the
state
-
of
-
the
-
art

infrastructure already in
place and contributing to frontier research under the supervision of
prominent

accelerator
scientists.

Simultaneously,

students w
ould

learn the fundamentals of accelerator physics

and engineering in courses, such as the proposed
PHYS 560
,

taught by
TRIUMF
scientists.
The

new
research opportunities
together

with the formal course offerings

will

att
ract
high

caliber students to UBC.


TRIUMF’s Accelerator Division is committed to pro

for this

course.

UBC graduate students in accelerator physics will be supervised or
