Postdoctoral position with specialization in microwave engineering for high power energy applications - Hiring in process/Finished, not possible to apply

The research conducted at the Department of Physics and Astronomy encompasses a wide range of physics topics, distributed over ten divisions. The department is located in the Ångström laboratory and employs nearly 400 people, 125 of whom are doctoral students. It offers a broad physics curriculum to undergraduate and graduate students, participation in nationally and internationally leading projects for researchers, and opportunities for partnership with industry and various outreach activities.

The Department of Physics and Astronomy is hosting the FREIA Division responsible for the FREIA Laboratory, where research is performed towards future particle accelerators and instrumentation. The FREIA laboratory operates complex equipment such as superconducting cryostats and microwave equipment for developing and testing particle accelerator instrumentation. Current projects are related to the: European Spallation Source (ESS), MAX IV Laboratory, High Luminosity upgrade of the LHC at CERN, development of free-electron lasers, and development of a compact X-ray laser and instrumentation in Uppsala.

The candidate is offered the opportunity to work in an exciting modern research area in physics and will have opportunities to interact and collaborate with leading groups in experimental physics and technology.

Project description: The FREIA Laboratory is engaged in the development of new RF/MW high power amplifiers based on solid state transistors in LDMOS and GaN technologies, for particle accelerators and other industrial applications. The successful candidate will work on three projects: (i) development of power amplifier modules at kilowatt level; (ii) development of power combiners and power amplifier systems at multiple kilowatt levels and (iii) development of microwave assisted industrial processing applications using microwave energy for materials processing. The research project will include a mix of theoretical and experimental work, with specialization on advanced high-power microwave engineering. The research will therefore profit significantly from the excellent measurement infrastructure available at FREIA laboratory and Ångström.

Work description:

• Develop high-efficiency solid state power amplifiers (SSPA) at multiple kilowatts level
• Develop low-loss high power combiners at multiple kilowatts level
• Perform microwave material characterization
• Develop microwave assisted industrial processing applications
• Participate in the operations of the FREIA laboratory i.e. the testing of superconducting RF cavities
• Participate in the development of RF systems for national and international accelerator projects such as ESS, CLIC, AWAKE and THz FEL.

Requirements: To qualify for an employment as a postdoctor you must have a PhD degree or a foreign degree equivalent to a PhD degree in physics, applied physics electrical engineering. The PhD degree must have been obtained no more than three years prior to the application deadline. The three year period can be extended due to circumstances such as sick leave, parental leave, duties in labour unions, etc. 

We are looking for qualified and motivated candidates with a strong interest in microwave engineering and/or accelerator physics. The candidate must have completed a course in microwave technology or equivalent.

Very good oral and written proficiency in English is a requirement as well as the capacity to work both independently and in a team.

Additional qualifications: The applicant should preferably have experience in microwave engineering and amplifier design. Excellent ratings are an advantage. The candidate should preferable have experience with the use of a microwave network analyzer (VNA), software for calculating EM-fields like HFSS, CST or similar and be familiar with the main concepts.

Applications could be written in Swedish or English and should include a brief description of research interests and relevant experience, CV, copies of certificates and diplomas, PhD thesis (or a draft thereof), PhD diploma and these and other documents which the applicant wishes to refer to. The applicant is invited to provide names and contact details of referees and/or attach recommendation letters.

Salary: Individual salary.

Starting date: 18-06-2021 or as otherwise agreed.

Type of employment: Temporary position 2 years according to central collective agreement.

Scope of employment: 100 %
