This honor is the highest bestowed by the U. Heather Whitley, a design physicist, was chosen for her work using path-integral Monte Carlo techniques to produce accurate quantum statistical potentials for use in molecular-dynamic codes and for applying these methods to first-principles understanding of thermal conductivity in ignition capsules for the National Ignition Facility NIF.

Long-lived 3 to 12 energy confinement times predator-prey type limit cycle oscillations LCOs are observed to follow immediately after the coherent edge harmonic oscillations EHOs disappear in wide-pedestal ELM-free QH-mode plasmas. The temporal dynamics can be explained as follows: Observations of oscillations in edge transport relevant parameters including that of Langmuir probe ion saturation current indicate a potentially significant contribution of this LCO mechanism to modulated pedestal transport in wide-pedestal QH-mode.
The frequency of these LCOs is found to scale inversely with pedestal density and also the period of the cycles can be actively controlled by applying electron cyclotron heating ECH which also improves confinement of this regime. The boundary plasma in a magnetic fusion device has an enormous impact on its ability to achieve both good fusion performance in the core and sufficient mitigation of waste heat conducted to plasma facing materials.
This is due to the integration of a number of transport and stability phenomena, over a relatively small boundary layer, which serves to regulate the flow of heat and particles out of the confined plasma, and which determines how that flow interacts with material surfaces.
How these processes play out at parameters relevant to burning plasmas will have a significant impact on reactor viability. Experimental work on the Alcator C-Mod tokamak has explored critical boundary physics issues at parameters relevant to the ITER device, which is under construction.
These parameters include toroidal and poloidal magnetic field, absolute plasma density, and heat flux to material surfaces. The device has demonstrated an edge transport barrier having a plasma pressure very near that required for ITER, and has shown success in mitigating heat flux to an ITER-like divertor.
Interest is growing quickly in the prospects for compact high magnetic field devices for fusion, largely due to recent advances in the performance of high temperature superconductors, which could enable steady state operation at twice the ITER field. The impact of boundary physics must be examined in this context, and C-Mod results at up to 8T provide a path forward for projecting to very high field devices.

Biography. Kiyong Kim earned his Ph.D. at the University of Maryland under Prof. Howard Milchberg, and received the Marshall N. Rosenbluth Outstanding Doctoral Thesis Award presented by . Marshall Rosenbluth () During the defense of his Ph.D. thesis at the University of Chicago, two of his examiners, Enrico Fermi and Edward Teller, got into an argument.
"It went on and on," recalled Harold Agnew, then a graduate student at Chicago, who eventually directed the weapons laboratory at Los Alamos, N.M. an award given. Seth Davidovits (B.S. '10, Applied Physics), a graduate of the Program in Plasma Physics in the Princeton University Department of Astrophysical Sciences, has won the Marshall N.
