I currently work in the Accelerator Physics group of ASTeC. My primary role is to lead the development of photocathodes for photoinjectors used in next generation electron accelerators. This project involves expanding our expertise in the growth of photocathode materials and the establishment of test equipment to characterise them. Current facilities include a low energy test facility to measure the intrinsic emittance of photocathode materials at room and low temperature and surface analysis facilities to characterise the composition and morphology of candidate materials and preparation procedures.
In addition to working on photocathodes I also play a role in the development of the VELA/CLARA facilities, including the new high repetition rate photoinjector. As part of the commissioning, I have responsibility for the measurement of momentum, momentum spread and dispersion along the accelerator.
Prior to transferring to ASTeC, I was manager of mid-range facilities at Daresbury Laboratory, which included the national centre for electron spectroscopy and surface analysis (NCESS) and the medium energy ion scattering facility (MEIS). Before that I had been a support scientist on the MEIS facility, which I helped to build and commission when I joined the laboratory in 1995.
Before joining the laboratory I completed a Ph.D. in Surface Physics at the University of Warwick sponsored by AEA Technology Ltd, having previously obtained an M.Sc. in Surface Science and Technology from Loughborough University of Technology and a B.Sc. in Applied Chemistry from Brunel University. I have also worked at Coventry Polytechnic as a research assistant investigating diffusion in II-VI semiconductors and for the Malaysian Government carrying out research into the applications of Natural Rubber.
