Doctoral
Research
I am presently a PhD student at the
University
of Tennesee - Knoxville working
under Dr.
Robert Grzywacz, my graduate advisor.
There are two major projects I am
working on for my thesis.
The first project is an experiment
we conducted at the National
Superconducting Cyclotron Laboratory
(NSCL) in Michigan
State University to study the
systematics of low lying states in
71Ni and 73Ni populated via the beta
decay of 71Co and 73Co respectively.
The investigated nuclei were obtained
from a fragmentation reaction of a
140MeV 86Kr beam at 20pnA on a 9Be
target and separated by the A1900
fragment separator.The experimental
setup consisted primarily of a Double-sided
Silicon Strip Detector (DSSD) for
ion-beta tagging and the NSCL Segmented
Germanium Array (SeGA) to detect the
emitted γ-rays. The data acquisition
system we used was based on a new
generation of digital pulse processing
modules (Pixie-16) made by XIA and
further developed at the University
of Tennessee and Oak
Ridge National Laboratory.
The second project involves
designing and developing a system
of detectors for the measurement of
short-lived (nanosecond) isomers.
The isomers will be created using
deep inelastic collisionsof Ga/Ge
beams on a Te target. The desired
reaction products will trigger a start
signal on a dual MCP setup and corelated
gamma-rays will be detected by germanium
clover detectors from the CARDS array.A
proof of principle experiment for
the detector system has been apporved
at the Holifield
Radioactive Ion Beam Facility(HRIBF)
at ORNL.
The project is headed by Dr.
Wojtek Królas from the
Institute of Nuclear Physics, Polish
Academy of Sciences in Kraków,
Poland.

Master
Thesis and other
projects
The masters was obtained at
University
of North Dakota working
under my graduate advisor Dr.
Kanishka Marasinghe.
Our project involved finding
the structure of a series of
novel rare-earth phosphate
glasses (REPG). Phosphate
glasses in general are quite
unstable on their own and are
extremely hygroscopic. When
doped with certain metals,
these glasses become stable and
exhibit impressive optical
characteristics. Currently the
majority of REPG's used in
science and industry are in the
meta-phosphate range (i.e the
oxygen to phosphorous ratio is
~3). Preliminary studies of a
different family of these
REPG's in the ultra-phosphate
range (where (2.5 < [O]/[P]
< 3.0) has shown promising
results for industrial use. The
ultra-phosphate glasses have a
number of more deisreable
characteristics over their
counterparts, especial when
looking at optical properties.
In particular ultra-phosphates
have less concentration
quenching which makes them
attractive (potential) lasing
materials.
The properties of these
glasses depend heavily on their
structure and dynamics at the
atomic level. Our work was
concentrated at finding the
local and intermedient range
ordering of the REPG's using
neutron and x-ray diffraction
techniques. The research
project was funded by the Division
of Materials Research
of the National
Science Foundation
(NSF).
The experiments were
conducted at the Intense
Pulsed Neutron Source
(IPNS) using the Glass,
Liquid and Amorphous
Diffractomiter (GLAD).
IPNS a user facility at the Argone
National Lab (ANL)
funded in part by the
Department of Energy and run by
the University of Chicago.

Physics
Research
Project:
My summer
of 2002 was spent at Michigan
state university
building a the Modular Neutron
Array (MoNA) which is a large
area neutron detector. The
detector will be at the
National Super conducting
Cyclotron Laboratory (NSCL).
The project was a collaboration
of 12 undergraduate schools.
During our stay at the NSCL, we
built 32 bars of the detector
and conducted three tests: A
cosmic ray test, Shadow bar
test and a radioactive beam
experiment with 8Li
beam to observe the break up of
7Li to
6He and a neutron.
(This project was done with Dr.
Bryan A. ). More
information on the project is
available at http://groups.nscl.msu.edu/mona/.
The
Li-break up experiment was
presented at a poster session
during the CEU (Conference
experience for undergraduates)
program in October
2002.
