RF Cavity Simulator for LLRF Lab Testing

Your tasks

The main goal of the project is the development of an emulator of resonance cavities for beam acceleration. The emulator should be in a form of stand-alone electronic box which can be connected to a Low Level Radio Frequency (LLRF) system for laboratory tests. Such platform should allow continuous studies of control algorithms and firmware/software of the LLRF systems without disturbing the real cavity operation. Such a platform would also be used for training of on-call duty staff without risk of damaging real high-power RF system.

Your tasks will be:
Basic implementation of an RF cavity simulator:
  • Together with the LLRF experts work out a model of an RF system simulator which includes a resonance cavity simulator with configurable bandwidth and detuning, emulation of a resonator tuner, beam loading effects, disturbances like resonator detuning due to temperature drifts, high power amplifier non-linearity and noise
  • With support of electronic engineers implementation of the worked out model in a system on chip (SoC) using VHDL and C
  • Commissioning and test of the simulator on a given evaluation board with Xilinx RFSoC

Your profile

  • You study physics or electrical-engineering (minimum 4 semesters)
  • You had a course in VHDL and C programming
  • You have basic knowledge in digital signal processing
  • You are open-minded, communicative and enjoy working in an international team
  • You have not yet completed your Master’s thesis
