Position overview

We are seeking a Radiation Physicist to join our Radiation Protection Department (RPD) to support one or more SLAC accelerator facilities, beamlines and/or experimental facilities, for their radiation safe design and operation to protect the workers, users, public and the environment. The assigned facilities may include Stanford Synchrotron Radiation Laboratory (SSRL), the Linac Coherent Light Source (LCLS), Linac Coherent Light Source II (LCLS-II), FACET-II, LCLS-II High Energy projects, MEC upgrade projects, and/or test labs. The Radiation Physicist will also carry out responsibilities for the establishment and implementation of the radiological protection programs for the assigned facilities and/or RPD programs. The Radiation Physicist will also interact with staff scientists, engineers, technical and administrative personnel, users, contractors, regulators and other stakeholders; develop technical notes, operating procedures and program manuals. Additionally, the Radiation Physicist is expected to lead and/or participate in program assessments and provide training.  This position reports to the Group Leader, or senior staff in the Radiation Physics Group (RPG) within RPD.

Your specific responsibilities include:

  • Work independently under consultative direction toward long-range goals and objectives to innovate and push the boundaries of the scientific field.
  • Execute calculations (using Monte Carlo and analytic codes) and specify requirements for shielding and other radiation quantities for accelerators and beamlines.
  • Contribute to the design of radiation safety systems including access control system and beam containment system.
  • Develop, execute and oversee operation programs related to radiation safety systems, including facility authorization, configuration control, work plan configuration, etc.
  • Organize and oversee radiation measurements for commissioning and regular monitoring.
  • Organize and participate in review panels and working groups for radiation safety systems; review documents such as radiation safety procedures, engineering specifications and drawings, building submittal packages, etc.
  • Support continuous improvement and implementation of SLAC Radiation Protection Programs: dosimetry, instrumentation, radiological protection for public and environment, field operation, radioactive waste disposal, etc.
  • Perform research and development work on complex projects necessitating the origination and application of new and unique approaches.
