For the Large Research Facilities Division we are looking for a


RF Cavity Simulator for LLRF Lab Testing

Your tasks

The main goal of the project is development of an emulator of resonance cavities for beam acceleration. The emulator should be in a form of a 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:

Implementation of the RF cavity simulator:
  • Together with the LLRF experts you will learn the actual basic model of the RF system simulator which includes a resonance cavity simulator. You will work out model extension for 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 emulation
  • With support of electronic engineers you will implement the model extensions in a system on chip (SoC) using VHDL and C
  • Commissioning and test of the simulator on a given evaluation board with Xilinx Zynq UltraScale+

Your profile

  • You study physics or electrical‐engineering (minimum 4 semesters)
  • You had a course in VHDL and C programming
  • You have some experience with Xilinx Vivado tool and ModelSim
  • You have basic knowledge in digital signal processing and hands‐on experience with Python
  • You are open‐minded, communicative and enjoy working in an international team
  • You have not yet completed your Master’s thesis

We offer

Our institution is based on an interdisciplinary, innovative and dynamic collaboration.

The employment contract will be limited to 3 months.
