Dr. Sujit Bidhar graduated with his PhD in mechanical engineering from the University of Tokyo in 2012 specializing in fatigue, fracture mechanics, and finite element modelling in aluminium die cast. He is currently working at Fermilab where he is involved in new target material research and development, developing material models for future high energy beam target materials subjected to thermal shock, and nuclear irradiation damage to predict target lifetime. Dr. Bidhar has set up a lab-scale electrospinning unit and successfully fabricated different ceramic, metallic, and polymeric nanofibers; he is currently designing micromechanical experiments to evaluate single nanofiber mechanical properties using SEM, FIB, and AFM techniques. In the past, he has worked at the University of Tokyo as a researcher in the field of impact analysis on jet engine turbine blade made up of FRP composites, large scale finite element simulation on super computers using LS-DYNA. He has research interest and experience in computational mechanics, solid mechanics, structural analysis, fatigue and fracture, stress analysis, very large scale finite element simulations, image Based Finite Element Method using ANSYS,VOXELCON,LS-DYNA,ABAQUS, FrontISTR,HYPERMESH, MATLAB, Fatigue testing, X-ray CT. He also has experience in conducting experiments at high temperature and pressure environment, various metallurgical laboratory works, SEM micrographs, EDX, RAMAN spectroscopy, Slow strain rate tests.
Michael Geelhoed has worked at Fermi National Laboratory since 2006. He’s served in varying capacities and is currently Technical Support Leader at the lab’s Illinois Accelerator Research Center (IARC). His professional credits include being the lead project designer for temporary radioactive water filtration systems, coordinating the efforts of multiple in-house departments as well as contractors for various projects, and being responsible for the operations of IARC’s A2D2. He earned his bachelor’s degree in physics from Michigan State University and since earned his certificate of health physics as well as master’s in health physics from Illinois Institute of Technology. As a board member of the Midwest Chapter of the Health Physics Society he also has been published in Super Conductor Science and Technology, IEEE Transactions on Applied Superconductivity, and Cryogenics.
Dr. Thomas Kroc is an Applications physicist for Technology Development with the Illinois Accelerator Research Center (IARC). This position draws on his accumulated experience in fundamental high-energy physics research, nuclear power, medical physics, and accelerator physics. Since 2016 he has been Fermilab’s lead investigator in understanding the application of electron and x-ray beams for medical device sterilization. He was the primary author of IARC’s report on medical device sterilization to the NNSA, was a subject-matter expert with a DHS Non-Isotopic Alternative Technologies Working Group, and is now a member of a National Academies committee on Radioactive Sources: Applications and Alternative Technologies. As a member of, and finally head of, Fermilab’s Neutron Therapy Facility, he lead its successful 510(k) submission for its Neutron Therapy System, developed a new multi-leaf collimator, and adapted, installed, and commissioned a GE 8800 CT scanner to enable it to scan upright patients, in addition to clinical medical physics duties. Dr. Kroc managed the magnetic systems and designed the radiation shielding for the 5 MeV DC accelerator and its high current electron beam as part of Fermilab’s successful demonstration and subsequent operation of relativistic electron cooling. As an undergrad, Dr. Kroc studied physics and nuclear engineering including nuclear safeguards as an undergraduate researcher at Argonne National Laboratory. Dr. Kroc holds a PhD in Physics from the University of Illinois at Urbana-Champaign. He earned his undergraduate degree in Engineering Physics from The Ohio State University.
