The Good News!
Dr. Rajabali's Team is Creating 
an Ion Beam Lab
Associate Professor Dr. Mustafa Rajabali and his team are building an ion beam laboratory at Tennessee Tech University. The lab is a unique facility in that it involves only undergraduates in every aspect of its design, development and construction. It is envisioned to be a training ground for undergraduate science and engineering majors who intend to pursue graduate studies or a career path in applied physics. The facility will, among other things, be used for work related to Dr. Rajabali’s Department of Energy Grant.
By utilizing his grant, and teaching students how to get information and direction from departments across campus, Rajabali and his team have saved countless dollars and gained valuable hands-on experience. Examples of this team’s projects are impressive in both scope and cost savings. They have acquired the components from Oak Ridge National Lab’s Ion Beam Facility, designed the system to plug into a normal 20-amp circuit and use a high-power laser to produce an ion beam, developed plans to construct a Ti:Saph laser, built high-voltage safety and laser-safety interlocks, assembled a power generator, and rejuvenated three turbo-vacuum pumps.
Tech’s new ion-beam lab will incorporate many fields in physics and engineering and, eventually, the facility will support a multitude of projects such as laser spectroscopy of fast-ions, hyperfine structure studies for nuclear and atomic physics, molecular spectroscopy, trace element analysis, and detector and sensor characterization and development. The facility will support the interests of the faculty and students at Tennessee Tech while providing an advanced educational experience in physics and engineering for undergraduates.
The ingenuity and resourcefulness of Dr. Rajabali’s team has not only resulted in huge cost savings (costs incurred so far have been funded by grants), it has provided unique experiences for undergraduate students in acquiring knowledge, collaborating with other departments and facilities on campus, and in learning how to repair or build their own equipment. Invaluable lessons learned while building the facility.
Earth Sciences wins 43rd 
Annual GeoConclave
Tennessee Tech Earth Sciences students won Tennessee’s 43rd annual GeoConclave. Tennessee Tech students also placed first in the Rock Bowl!
The event took place this past weekend at Harrison Bay State Park near Chattanooga. Tennessee Tech students competed against students from Middle Tennessee State University, University of Tennessee-Knoxville and University of Tennessee-Martin. In the 43 years of GeoConclave, Tennessee Tech University students have won 20 times!
Additional congratulations go to the following students: Gabi Burke, 2nd place in Mineral ID; Kaiah Whited, 1st place in Rock ID; E Vigil, 2nd place in Fossil ID; Sydney Beltran, 1st place in Geologic Maps; Ben Lane, 1st place in Hydrogeologic Maps; and Gabi Burke, Kaiah Whited and E Vigil whose team placed 1st in the Rock Bowl! Wow! What a great showing!!! (Not sure who won the hammer toss, but it looks like fun!)
PS – Traditionally, Dr. Wayne Leimer (Professor Emeritus) would purchase a twelve-pack of Mr. Pibb for GeoConclave and the students would share it and take a picture if they won. If they did not win, they had to return the 12-pack to Dr. Leimer. This tradition continues today!

Biology Student Wins Second Place at GARD Conference
Xavier Jackson, a Wildlife and Fisheries Science major, won second place for his poster
presentation at the Global Amphibian and Reptile Disease (GARD) Conference in Knoxville,
TN. The goal of GARD 2022, according to the conference website, was “to bring together
scientists from across the globe to discuss various amphibian and reptile diseases,
organize facilitated discussions on…host-pathogen systems, and identify disease management
strategies that can be used to ensure the conservation of herpetofauna species for
generations to come.” Xavier’s presentation focused on a student-led surveillance
project for the salamander-eating fungus Batrachochytrium salamandrivorans, which
he and other Tennessee Tech students conducted in Fall 2021 with Aubree Hill, Ph.D.
The international GARD conference was co-sponsored by the Center for the Management,
Utilization and Protection of Water Resources (Water Center) at TTU, The University
of Tennessee, The National Science Foundation, The U.S. Geological Survey, Tennessee
