Fred B. Bateman (Fed)

Dr. Bateman joined the staff of the NIST Radiation Physics Division in 1998 as a research physicist. His primary responsibilities include maintenance and quality assurance for several electron accelerators and intramural research into radiation effects and novel dosimetry methods. The accelerator facilities support a broad user community, supporting government, academic and industrial researchers. These accelerators are employed in numerous applications such as homeland security, radiation hardness testing, detector development and medical and industrial dosimetry. In recent years, Dr. Bateman has overseen the addition of new radiation facilities including a clinical radiotherapy accelerator and a low-energy industrial electron beam testbed facility. The radiotherapy accelerator delivers therapy-quality radiation fields supporting the development of high-energy dosimetry standards and research into novel dosimetry techniques. Dr. Bateman is also spearheading the design and installation of a high-energy industrial electron-beam facility which will provide a testbed for high-dose rate dosimetry and sterilization applications.

Research Interests

In addition to developing new accelerator monitoring capabilities and experimental apparatus to support user projects, Dr. Bateman’s research includes the research and development of novel dosimetry methods for medical and industrial applications. Dr. Bateman is leading efforts in experimental design and electron beam testing of a photonic dosimetry system in support of the NIST-On-A-Chip (NOAC) program. Dr. Bateman has led bilateral comparison studies to validate the performance of a water calorimeter for high-energy clinical photon beams. Another ongoing effort is the development and testing of high-dose rate graphite calorimeters to measure electron beam doses in high-energy electron beams. Dr. Bateman also designs and conducts detailed Monte Carlo computer simulations to help inform experimental design and validate performance of sensing systems.
