Engineered Systems Tec 4/5 - 805 MHz HPRF Team
- Req. Number: IRC140222
- Organization : AOT-RFE/RF Engineering
- City, State: Los Alamos, New Mexico
What You Will Do
The Accelerator Operations and Technology Division (AOT), Radio Frequency Engineering (RFE) group is seeking an Engineered Systems Tec level 4 or level 5 for the High Power RF (HPRF) team.
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 (LINAC) utilizing high-power diacrode tubes, an 805-MHz coupled cavity LINAC utilizing high-power klystrons as the primary power source, a proton storage ring, and roughly a kilometer of beam transport lines that deliver beam to the five independent research programs.
The RFE group is principally responsible for all radio frequency (RF) systems. The group consists of three teams: (1) Low-Level RF (LLRF) focused on real-time phase and amplitude controls; (2) High-Power RF (HPRF) systems at 201 MHz; and (3) High-Power RF systems at 805 MHz.
This position will be filled at either the Engineered Systems Tec 4 or Engineered Systems Tec 5 level, depending on the skills of the selected candidate. Additional job responsibilities (outlined below) will be assigned if the candidate is hired at the higher level.
Engineered Systems Tec 4 ($71,200 - $112,900)
The successful candidate, working closely with other engineers, technologists and technicians, will contribute to the operation, troubleshooting, and maintenance of the LANSCE 201.25-MHz and 805-MHz high-power RF (HPRF) systems, including high-voltage power supplies and associated electronics, and high-power RF test stand development and operation.
The position will also involve working with High Voltage and RF engineers to plan and implement RF system upgrades, e.g., new klystron amplifiers and the newest solid-state high-voltage pulsed power systems. The position will involve prototype testing, data collection and analysis for design refinement of klystrons and modulators.
The successful candidate will also provide on-call support for the LANSCE high power RF systems after hours and on weekends. The on-call assignment will typically be for one week per month during accelerator operations (approximately 7 months per year).
Additionally, the position at this level contributes to and is responsible for planning, managing and analyzing RF system data to inform design enhancements for improving performance and reliability; planning, designing, implementing, and contribute to RF system upgrade projects, e.g. high-voltage converter modulator power systems and klystron modulator monitoring and control systems.
The successful candidate will also provide power electronics expertise to all segments of the group, particularly in the areas related to vacuum tube amplifiers and the equipment required to operate them.
Engineered Systems Tec 5 ($85,900 - $139,900)
In addition to what was outlined at the lower Engineered Systems Tec 4 level, the position at this level will be responsible for working with senior RF Technicians, Technologists and Engineers in the specification development and procurement of new klystron amplifiers and the newest solid-state high-voltage pulsed power systems.
