Responsibilities will include:

• Design, develop, construct, implement and maintain high-power rf systems for particle accelerator applications utilizing solid-state rf amplifier devices for power generation in the 10MHz to 1GHz frequency range.
• Apply analytical methods and use circuit simulation software tools to design and optimize solid state rf power amplifier performance.
• Design and implement interlock systems needed to protect high-power rf components and systems.
• Analyze rf system performance to provide fault analysis and improve operation reliability.
• Act as lead engineer in troubleshooting high power rf systems and independently design and implement system improvements.
• Plan and lead R&D programs for development related to high-power rf systems and devices.
• Independently perform complex electrical and electronics engineering analysis and troubleshoot and debug rf systems.
• Formulate and implement maintenance and operating guidelines for SSA systems. Provide engineering support to Operation and Analysis Group.
• May be required to perform other duties as assigned.

• Bachelors and 15+ years’ experience, Masters and 12+ years’ experience, PhD and 10+ years’ experience, or equivalent.
• Experience in high-power rf system design, construction, operation and maintenance, with emphasis on multi-kilowatt solid state rf power amplifier technology.
• A working knowledge of high-power rf technology at frequencies between 10MHz and 1,000MHz, and hands-on experience with LDMOS solid state rf power amplifiers.
• Experience with high-power rf components, including waveguide transmission systems, and devices such as ferrite circulators and isolators, rf power couplers, rf loads, rf power combiners/splitters, and directional couplers.
• Operational knowledge of Multikilowatt rf amplifier systems.
• Knowledge in understanding complex systems and identifying and isolating problems.
• Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork.
• Interpersonal skills, oral and written communication skills, and ability to interact with people at all levels both within and outside the laboratory.

Preferred Knowledge, Skills, and Experience

• Knowledge and experience with accelerating cavities and vacuum-tube rf technology.
• Operating experience with AC Power Distribution Systems for high-power rf installations.

Argonne employees, and certain guest researchers and contractors, are subject to particular restrictions related to participation in Foreign Government Sponsored or Affiliated Activities, as defined and detailed in United States Department of Energy Order 486.1A. You will be asked to disclose any such participation in the application phase for review by Argonne’s Legal Department.

All Argonne offers of employment are contingent upon a background check that includes an assessment of criminal conviction history conducted on an individualized and case-by-case basis. Please be advised that Argonne positions require upon hire (or may require in the future) for the individual be to obtain a government access authorization that involves additional background check requirements. Failure to obtain or maintain such government access authorization could result in the withdrawal of a job offer or future termination of employment.
