Accelerator Diagnostics Electrical Engineer

Accelerator Diagnostics Electrical Engineer Job ID 6681 Location SLAC

• Menlo Park, CA Full-Time Regular
• SLAC Job Postings
• SLAC National Accelerator Laboratory's SPEAR3 is one of the four US third generation lightsources' electron storage rings dedicated to producing brilliant X-ray beams.

SPEAR3 serves Stanford Synchrotron Radiation Lightsource (SSRL), a national user facility with the longest history of utilizing synchrotron radiation for multi-disciplinary experiments studying many of the most pressing scientific issues facing humanity including those in medicine, biology, energy, and the environment. SSRL supports over 1500 research scientists annually. SPEAR3 operates 24 hours per day, seven days per week during each annual 5000-hour user run. Members of our SSRL Accelerator Team are responsible for operating and improving electron accelerators that produce high brightness x-rays for SSRL. The accelerator complex consists of 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. The accelerator team has expertise in instrumentation, fast feedback systems, real-time software applications, systems analysis, and accelerator beam dynamics. The group conducts regular testing of system components with live beam to demonstrate new concepts and collaborates with other groups at SLAC for development, prototype implementation, system deployment and systems analysis. The SSRL Accelerator RF Group is responsible for maintaining, operating, and improving the RF systems that power the electron storage ring and its injector. These systems include high peak power klystrons, solid state amplifiers, low-level RF (LLRF) control systems, high-voltage power supplies, and precision feedback loops critical to the stability of these systems. The accelerator beam diagnostics and control team is responsible for hardware diagnostics and control systems, fast-acting interlock systems, motion control systems and radio-frequency systems. Electron beam diagnostic and instrumentation systems measure and control the spatial and temporal beam distributions, beam position stability and other relevant operational parameters. Hardware diagnostics and controls include timing systems, motion control, vacuum systems, magnets, RF, temperature monitoring and cooling water. All systems are controlled with advanced Ethernet-connected communications with tightly regulated feedback loops to maintain high-precision stability. Development of signal processing algorithms, control architectures and advanced feedback techniques are part of the ongoing effort. We are seeking to hire a Test engineer with strong background in electrical or electronics engineering to maintain, design, build, integrate, and troubleshoot advanced engineering systems in the SSRL accelerator complex and interface with scientific, engineering and technical staff across the lab and work on a range of technical systems using both engineering and applied physics skills.
