Laser-driven energetic proton accelerators have the potential to provide compact sources of MeV energy, low emittance, sub-picosecond duration proton beams for a variety of applications. The primary impediment to their wider adoption is the challenge of shot-to-shot reproducibility and tuning of the parameters to optimize desirable proton beam qualities in a multi-dimensional parameter space. Recent developments in laser technology and control systems, making available multi-Hz delivery of joule-class, relativistically-intense laser pulses with automated control, combined with online diagnostics have enabled the automated scanning of parameters space, quantification of uncertainty and use of feedback loops for optimization of desirable outputs (e.g. proton beam maximum energy). Bayesian optimization has already demonstrated impressive gain in x-ray generation when used in conjunction with a laser wakefield accelerator [1]. Here, we discuss the preliminary results from experiments expanding this tool to laser-driven proton acceleration.

UKRI Deadlines

Due to the implementation of a new UKRI funding system (TFS) there will be a fixed quarterly deadlines for some grants which would previously have been on open calls, this is to allow necessary system amendments and updates.

The first deadline after implementation will be 28th September 2023 and applies to those calls listed below:

EPSRC New Investigator Award

EPSRC Network Grant

EPSRC Post Doctoral Fellowship

EPSRC Open Fellowship

EPSRC Open Plus Fellowship

EPSRC Working with overseas scientists

EPSRC Standard research grant

EPSRC Discipline hopping in ICT

EPSRC Overseas travel grant
