Geneva, Switzerland What you'll do
You will contribute to the design and development of laser and optical systems for the Advanced Wakefield Accelerator Experiment (AWAKE) at CERN, with a strong focus on laser, opto-mechanical and optical control design and integration.
The systems are used for ionizing efficiently 10 m long Rb plasma columns, and for optically synchronizing multiple laser and charge particle beams with femtosecond accuracy. The tasks include carrying out optical simulations and tolerancing studies, designing and prototyping and commissioning opto-mechanical and fiber systems, construct and operate ultrafast laser and optical systems and associated control devices, ensuring system reliability under tight operational constraints.
You will collaborate closely with colleagues in the lasers and photocathodes section in optics and lasers research, intelligent control systems to integration of sensors and actuators, as well as supporting system installation and commissioning, and documenting the work for future AWAKE operation and maintenance.
Your responsibilities
- Optical system design for high-precision measurement / imaging / alignment systems. This includes both optical layout, component selection, and mechanical integration.
- Perform research studies (optical, mechanical, thermal, vibrational) to ensure system performance under realistic operational conditions.
- Carry out optical simulations (e.g. ray tracing, wave-optics, stray light) using relevant software tools.
- Design, prototype, assemble and test opto-mechanical assemblies, mounts with actuators, alignment devices, etc.
- Ensure optical design supports alignment, stability, environmental robustness (e.g. tolerance to temperature changes, vibrations, possibly radiation).
- Work closely with control systems engineers to integrate actuators / sensors, feedback systems, alignment control, etc. Optional involvement in firmware / software / system calibration is a plus.
- Collaborate with multidisciplinary teams (optics, mechanical, electronics / controls) to deliver reliable, accurate systems.
- Document design, test plans and reports; assist in installation, verification, and maintenance of optical systems.
