**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. **Your 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. + Propose and pursue new directions for improving performance of SSRL accelerator performance. + Participate in accelerator physics measurements and experiments during our regularly scheduled machine development periods. + Take a leading role in 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: The Staff Scientist level is a regular-continuing position and requires a review and evaluation of documented scientific achievements. Applicants should include a cover letter, a statement of research including brief summary of accomplishments, a curriculum vitae, a list of publications, and names of three references for future letters of recommendation with the application. **To be successful in this position you will bring:** + A PhD in accelerator physics or related field or equivalent experience with minimum 4 years of relevant experience in accelerator and storage ring physics. + Comprehensive knowledge of storage ring physics including linear and nonlinear beam optics and lattice design. + Hands-on accelerator expertise, including the ability to quickly diagnose problems that develop with the accelerators during operations. + Capability of innovative and independent research. + Demonstrated expertise with computer modeling codes as well as strong programming skills. + Good verbal and written communication skills and the ability to clearly document scientific research and projects. **SLAC Employee Competencies:** + Dependability: Can be relied upon to deliver results with a sense of personal responsibility for expected outcomes. + Initiative: Pursues work and interactions proactively with optimism, positive energy, and motivation to move things forward. + Adaptability: Flexes as needed when change occurs, maintain an open outlook while adjusting and accommodating changes. + Communication: Ensures effective information flow to various audiences and creates and delivers clear, appropriate written, spoken, presented messages. + Relationships: Builds relationships to foster trust, collaboration, and a positive climate to achieve common goals. + Effective Decisions: Uses job knowledge and solid judgment to make quality decisions in a timely manner. + Self-Development: Pursues a variety of venues and opportunities to continue learning and developing. **Physical requirements and Working conditions:** + Consistent with its obligations under the law, SLAC will provide reasonable accommodation to any employee with a disability who requires accommodation to perform the essential functions of his or her job. **Work standards:** + **Interpersonal Skills** : Demonstrates the ability to work well with internal and external stakeholders and clients. + **Promote Culture of Safety** : Demonstrates commitment to personal responsibility and value for environment, safety and security; communicates related concerns; uses and promotes safe behaviors based on training and lessons learned.Meets the applicable roles and responsibilities as described in the ESH Manual, Chapter 1 General Policy and Responsibilities
