What You Will Do

The Accelerator Operations and Technology Division (AOT), Radio Frequency Engineering (RFE) group is seeking a Scientist.

The AOT division maintains, operates, and upgrades all accelerator systems used at the Los Alamos Neutron Science Center (LANSCE) complex. These consist of two 750-keV Cockcroft-Walton-based injector systems (H+ and H- systems), a 201.25-MHz drift tube linear accelerator utilizing high-power diacrode tubes, an 805-MHz coupled cavity linac utilizing klystrons as the primary power source, a proton storage ring, and roughly a kilometer of beam transport lines that feed beam to the five independent research programs. The RFE group is principally responsible for all RF systems, pulsed power systems, and high-power DC power supplies used to operate magnets on the beam transport lines. Low-level RF (LLRF) control and monitoring of the various RF sources used to drive the beam is critical to the high performance and successful operation of the accelerator.

As a member of the AOT-RFE, DC & Pulsed Power Engineering team, the successful candidate, working closely with other engineers, technologists and technicians, will contribute to the operation, troubleshooting, and maintenance of the LANSCE Injector, DC magnet power supplies (Sorensen, Magna-Power, DBx modules, Alpha, California Instruments) and pulsed power systems, including high-voltage power supplies and associated electronics, high-voltage/high-current power supplies and associated electronics, and fast rise-time beam-kicker systems.

The position will also involve working under the direction of senior engineers to plan and implement pulsed power systems, DC magnet power supplies, magnet mapping and injector systems upgrades, e.g., Blumlein modulators, power electronic systems, and associated high-voltage pulsed power systems, Cockcroft Walton-based injector systems, analysis and control systems, extractor, deflector, chopper, bouncer and 40kv systems and high-current DC power supplies.

The successful candidate will also provide on-call support for the LANSCE DC & Pulsed Power team after hours and on weekends. The on-call assignment will typically be one week per month during accelerator operations, which spans about seven months per year.
