Graduate Scholarship Awards
Alexander Meadows is a senior graduate student completing his Ph.D. in electrical engineering and performing research on laser-plasma interactions and advanced laser development at Colorado State University. He began in this field in 2012 while pursuing a master’s degree at the University of Texas at Austin, where he joined the Texas Petawatt laser laboratory. This large laser facility served as the site of the experimental work for his master’s degree, which was based on research performed by irradiating ultrathin targets at extremely high intensities with an ultrashort laser pulse. In the following years, Alex also performed laser-plasma research at the Extreme Light Infrastructure project in Europe and worked in various precision optical production facilities on cutting-edge scientific products. Alex came to Colorado State University in 2017 and has worked on high average power and high peak power lasers for the production of extreme plasma states of matter. His doctoral work is based on the development of a few-cycle laser beamline for the irradiation of nanostructured solid targets at relativistic intensities of 1020 W/cm2 with pulses of 3-5 fs duration. This will create a dramatically different plasma environment than that in typical solid target laser experiments, with applications including the production of high-brightness x-ray sources, energetic collimated sources of ion and electron beams, and quasi-monoenergetic pulses of neutrons.
Nathan Giha joined the Detection for Nuclear Nonproliferation Group as an undergraduate at the University of Michigan, where he developed silicon photomultiplier readout electronics for compact neutron imaging systems. In Fall of 2019, he continued with the group as a Ph.D. student.
