IBeAM User
Qualification Process
The ASU 1.7 MV Tandetron Ion Accelerator in its entirety is a
complex
machine involving a large number of electrical and mechanical components
as
well as vacuum systems interacting to produce MeV ion beams for materials
analysis
and modification. User qualification and training is, therefore conducted
in
stages to allow as much “user friendliness” and simplicity as
possible. To
become a qualified user the following procedure should be
followed.
1.
READ the IBeAM Users Manual
through
section III and become familiar with the concepts of the ion beam analysis
technique you want to use (e.g. RBS, PIXE, ERD
etc.).
A useful tutorial is linked
from
this Web Site. Also books and literature are recommended at the back of
the
IBeAM Users Manual.
2.
MAKE an APPOINTMENT with the lab
manager, Barry Wilkens (barry.wilkens@asu.edu)
to begin training. At the lab managers discretion you may be allowed to
train
with a designated veteran user. Potential users are invited (and
encouraged) to
sit in with veteran colleague/users to observe the procedures of sample
transfer and data acquisition prior to their own training
appointment.
3.
COME to YOUR SESSION with a real sample(s) so
that
you may gain the added value of useful data as well as accelerator
training.
The sessions consist of
learning
the basic components (and functions) of the accelerator, beam line and end
chamber. Level I Users will become competent in successfully loading (and
unloading) samples as well as data acquisition, saving and fitting
procedures.
4.
AFTER TWO or THREE SESSIONS of working with the
lab
manager the new IBeAM User will be able to schedule beam time and work
independently (with the lab manager or a veteran user in close proximity
to
assist with problems or questions). As usage level warrants the user may
be
trained to adjust beam parameters (e.g. beam energy) and shut down machine
(User Level II) and possibly to User Level III where all features of
accelerator operation (including source start up) are
addressed.
5.
OTHER DETAILS: The user should be aware that
there
is a nominal hourly fee to be charged to his/her research account based on
assisted or unassisted use and for non-proprietary vs. proprietary (not so
nominal) work. Contact Barry
Wilkens
for this information and with any other questions you might
have.
