Linear Accelerator information

What are the key skills and qualifications needed to thrive in the Linear Accelerator position, and why are they important?

To thrive as a Linear Accelerator Operator (also known as a Linac Operator or Medical Linear Accelerator Technologist), you need a solid understanding of radiation physics, machine operation, and safety protocols, usually supported by a degree in medical physics, radiation therapy, or a related technical field. Familiarity with sophisticated linear accelerator systems, imaging software, and relevant certifications such as ARRT (American Registry of Radiologic Technologists) are typically required. Strong attention to detail, communication skills, and the ability to collaborate within a multidisciplinary team are critical soft skills. These competencies are vital for ensuring accurate treatment, maintaining patient and staff safety, and supporting effective clinical workflows.

What are typical daily responsibilities for a Linear Accelerator Operator in a clinical setting?

As a Linear Accelerator Operator, your primary responsibilities include setting up and calibrating the linear accelerator, delivering prescribed radiation treatments to patients with precision, and monitoring both patient condition and equipment performance during sessions. You will collaborate closely with radiation oncologists, physicists, and dosimetrists to interpret treatment plans and verify accurate alignment. Maintaining thorough documentation and conducting routine quality assurance checks are also essential aspects of the role. These tasks ensure that patients receive safe, effective care and that the equipment functions properly each day.

What is a Linear Accelerator job?

A Linear Accelerator (Linac) job typically involves operating and maintaining a medical or industrial linear accelerator, which is used to deliver high-energy radiation for cancer treatment or scientific applications. Professionals in this role, often radiation therapists or medical physicists, ensure the equipment functions safely and accurately. They work closely with oncologists, engineers, and other specialists to calibrate machines and adhere to safety protocols. Additionally, they may perform quality assurance checks, troubleshoot technical issues, and assist in patient treatment planning.

Associate Staff Scientist - SSRL Accelerator Physics

Associate Staff Scientist - SSRL Accelerator Physics

SLAC National Accelerator Laboratory

Menlo Park, CA • On-site

Full-time

Posted 12 days ago

Job description

Position Overview:
SLAC National Accelerator Laboratory's SPEAR3 is one of the four US Department of Energy synchrotron light sources electron storage rings dedicated to producing brilliant X-ray beams. SPEAR3 serves Stanford Synchrotron Radiation Lightsource (SSRL), a national user facility with a long history of utilizing synchrotron radiation for multi-disciplinary experiments.
We are seeking an Accelerator Physicist to join our Accelerator Physics Group within the SSRL Accelerator Division. This group's responsibilities include:
  • Physics support for the maintenance and operation of the SSRL accelerator complex, which includes an RF electron gun, 120-MeV linear accelerator, a 10-Hz cycling booster synchrotron to accelerate electrons from 120 MeV to 3 GeV, and the main SPEAR3 storage ring that emits x-ray synchrotron radiation from bend magnets, wigglers and undulators.
  • Propose and help design, manage, and execute upgrades of the existing SSRL accelerators to improve their performance and/or reliability.
  • Design a next generation storage ring as a future source to serve the SSRL photon science community.

This is an exciting time for the SSRL accelerator team. The Accelerator Physics Group is exploring options for a next generation light source for SSRL. We are investigating which technologies to push to enhance performance of a future light source beyond sources currently in operation or construction. We are working closely with SSRL photon scientists to establish a strong scientific case for a new SSRL light source.
You r specific responsibilities include:
  • Contribute to the Accelerator Physics Group ongoing effort to maintain and improve the performance of the SPEAR3 storage ring and its injector.
  • Participate in accelerator physics measurements and experiments during our regularly scheduled machine development periods.
  • Contribute to design studies for a future next generation light source for SSRL. This work will include simulations and optimization of linear and nonlinear storage ring dynamics.
  • Other duties may also be assigned.

Note : This position is posted at the Associate Staff Scientist level. The Associate Scientist position is a 3-to-5-year fixed-term position and the entry level in the Staff Scientist career path. The Associate Scientist position is scheduled to be assessed after the 3 to 5-year period, with the possibility of appointment to the Staff Scientist level.
