JOB DESCRIPTION

The Accelerator and Source Division (ASD) operates an accelerator complex with a 6 GeV electron storage ring, which is the source of the X-rays that are exploited on the experimental stations. In 2019, the ESRF will implement a new ultra-low emittance ring to become the world’s first Extremely Brilliant Source (ESRF-EBS project) of hard X-rays. As part of the ASD, the Radio Frequency (RF) group operates 352 MHz high-power amplifiers that feed the accelerating cavities of the Booster and Storage ring of the ESRF.

As an Engineer in the RF group your main missions will be:

  • Follow up the high-power radio-frequency transmitters
    • 1.3 MW CW klystron transmitters at 352.2 MHz
    • 150 kW solid state amplifiers at 352.2 MHz
  • Participate in the upgrade and re-commissioning of the RF systems in the frame of ESRF-EBS
  • Pursue the R&D effort under way at the ESRF in the field of efficient high-power solid-state amplifiers and their power combiners
  • Carry out a technological watch on worldwide R&D on high-efficiency RF power sources
  • Participate in the safe and reliable operation of the existing RF system

Moreover, as a member of the Accelerator and Source Division, you will be required to contribute with up to 15 % of your time to the operation of the accelerator complex on shift work for service to users and participate in the RF standby duty.

 

PROFILE, SKILLS AND EXPERIENCE

  • Higher university degree (Master or equivalent 300 ECTS diploma) in Electrical and RF Engineering
  • 7 to 15 years of experience in high-power RF amplifiers, klystrons and solid-state amplifiers
  • Expertise in RF transmission, detection and measurement techniques,
