Trainee for a load-lock system for the travelling-wave RF photogun

vor 2 Wochen


Villigen PSI AG, Schweiz Paul Scherrer Institut Vollzeit CHF 45'000 - CHF 60'000 pro Jahr
Your tasks

The travelling-wave TW RF photogun has demonstrated excellent performance during high-power testing. However, in the current design, there are areas to improve in the RF fingers and cathode alignment. The current system limits operational flexibility when operating with semiconductor photocathodes and also lacks the reproducibility of the cathode alignment that requires ~100 micron precision.

This project aims to develop an improved photocathode load-lock system incorporating a new spring-based design alignment system to enhance reproducibility and allow use of semiconductor cathode materials. This project is divided into two parts:

  • Core Task: Develop a mechanical concept and simulation/model for the new load-lock system
  • Advanced Task (for experienced students): Produce a system prototype and/or test concepts

This work is vital to the further development of the feasibility of the TW photogun for use in SwissFEL where the semiconductor photocathodes must be able to be exchanged under vacuum.

Your profile
  • You are a student in mechanical engineering or a related field, and you are at least in your ultimate year of undergraduate study (minimum 4 semesters)
  • Interest in vacuum, high power electronics or RF systems is advantageous
  • You have not yet completed your Master's thesis
We offer

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

The contract will be limited to 3 months.
