Thomas M. Miller is a Senior Neutronics Scientist in the Spallation Neutron Source (SNS) Second Target Station (STS) Neutronics Group.
In the past he worked as a senior research and development staff member of the Nuclear Data and Criticality Safety group within the Reactor and Nuclear Systems Division at Oak Ridge National Laboratory (ORNL). He received a Ph.D. in Nuclear Engineering from the University of Tennessee in 2004. His Ph.D. dissertation involved creating an event generator to model the particle production of nucleus-nucleus collisions for charged particles as heavy as lead with energies up to 22.5 GeV and incorporating this into the Monte Carlo code HETC to create HETC-HEDS. Since finishing his Ph.D., Dr. Miller has work at the Bettis Atomic Power Laboratory in Pittsburgh, Pennsylvania and ORNL. His work has primarily involved the application of fixed-source radiation transport codes. Examples include designing radiation shielding for the US Naval Reactors Program, investigating the use of bremsstrahlung sources created by an electron linac to actively interrogate maritime cargo for hidden special nuclear material, the design and evaluation of a shielding benchmark experiment with a pulsed critical fissile solution source, evaluating the variation of neutron and photon terrestrial background due to extraterrestrial sources, and developing a tool to use inverse algorithms to identify elemental composition of particulate samples analyzed by a scanning electron microscope.
