Electronics Engineer – Femtosecond Feedback and Stabilisation of Particle Accelerators

The Accelerator Science and Technology Centre (ASTeC) is engaged in underpinning accelerator R&D for a future x-ray Free ElectronLaser (FEL) facility, and is constructing an accelerator test facility (CLARA)to prove novel concepts and technologies that would provide such a facility aninternationally leading capability. A key goal of CLARA, and a future UK-FELfacility, is the achievement of femtosecond level synchronisation and stabilityof accelerated beams, high-power and low-level RF, integrated and end-userlaser systems. The achievement of such synchronisation levels would fundamentally expand the science capability of a UK-FEL facility.

ASTeC is seeking to appoint an engineer or physicist to develop electronic systems and control theory solutions for the stability and synchronisation R&D program on the CLARA accelerator test facility. You will work closely with physicists and engineers who are developing femtosecond level beam arrival monitors, laser-based RF timing distribution and precision RF measurement and feedback. You will apply your expertise in modern controls systems and feedback theory to identify performance limiting factors with the laser, high-voltage, RF and electronic and accelerator systems; working with STFC and university engineers and scientists. You will design and install appropriate electronic measurement systems and design and propose feedback/feed forward systems for optimising electron beam stability on the CLARA FEL test facility.

You will have significant experience in modern controls systems and feedback theory, and experience in digital and analogue electronics and FPGA programming.
You will have a master degree or PhD in engineering or physics with a significant modern controls theory or electronics emphasis; they will ideally have experience in one or more of low noise electronics, feedback and control systems, low-level RF electronics. While direct experience in particle accelerator systems is highly desirable, candidates with high level of relevant experience from other fields are encouraged to apply.

The post will be based in the Beam Diagnostics & Lasers group of ASTeC, STFC Daresbury National Laboratory, with significant opportunities for collaboration with international laboratories with large scale accelerator facilities.

List of Duties/Work Program/Responsibilities

  • using your expertise in controls theory and feedback, undertake the experimental identification of stability limiting factors in laser, high voltage, RF and other accelerator systems
  • to propose and implement appropriate feedback and feed forward systems on critical systems to improve the electron beam stability of CLARA
  • contribute to the definition of a wide program of a global feedback and stabilization systems for CLARA and UK-FEL.
