The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of matter and materials, energy and environment and human health. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether PSI employs 2100 people.

For the SwissFEL Project within the SwissFEL Beam Dynamics Group we are looking for a

Trainee
Orbit Response Measurement for BPM Calibration
Your tasks
The Free Electron Laser of the Paul Scherrer Institute (SwissFEL) transports a relativistic electron beam over 500 m with micron precision in the transverse position. Beam Position Monitors (BPMs) are used to determine the transverse position, but the 8PM signal has only been pre-calculated before installation in the SwissFEL beamline. lt still requires a dedicated machine study to compare the theoretical orbit oscillation with the measurement to improve upon the resolution. The model dependent prediction can be cross-checked with a few BPMs, which has been calibrated by external movers independently, and then extrapolated over the entire machine. Your task is to develop the measurement routine, carry out the measurement during machine development shifts and supply the BPM-group with the correct calibration factors.
Your profile
  • Student in physics and you are at least in your penultimate year of master studies
  • Interest in experimental measurements as well as in simulations
  • Open-minded person, communicative, and you enjoy working in an international team
