Research and Scholarship

Current Research

  • Particle accelerator applications (medical, security, energy)
  • Particle accelerator reliability
  • Electromagnetic wave propagation in; inhomogeneous media, periodic structures, strongly dispersive media
  • Particle/wave interaction mediated via metamaterial/photonic-crystals
  • Surface effects in RF breakdown phenomena (topology, chemistry, etc)
  • Novel Electromagnetic media (HTC proximity effect, metamaterials)
  • Electromagnetic research:  numerical, theoretical, experimental
  • Modelling RF structures

My current research portfolio focuses on electromagnetic wave propagation and charged particle interactions, in inhomogeneous media, periodic structures and strongly dispersive media, using experimental and numerical techniques. This includes developing an understanding of the interaction between charged particle beams and electromagnetic waves mediated via metamaterials/photonic-crystals. For examples metamaterials give rise to a novel dispersion relation, which determines a unique wave particle relationship, via the frequency dependence of the metamaterial. Investigations in the non-linear high power regime and how Complementary Split Ring Resonators function and communicate information between associated unit cells has proved particularly fruitful. This work is starting to attract interest within the UK commercial sector with invited talks to several commercial companies, currently funded by the AFOSR, and forms the basis for the America MURI on Transformative Electromagnetic media collaboration.

The above research underpins my main area of interest the development of novel particle accelerator technologies utilising metamaterials and Photonic Crystals (PC) to examine standing-wave and travelling-wave structures for particle acceleration. This area also encompasses the use of PC structures as compact light sources and for the generation of high power electromagnetic waves.  This work, supported by a prestigious Challenging Engineering grant, has focused in the 10’s of GHz regime of the electromagnetic spectrum, and I am keen to move towards investigating the THz regime using high powered lasers to excite electromagnetic waves in micro-fabricated resonant structures.

My current research also involves conventional accelerator technologies where I am investigate the limiting factors and design of Resonant RF Cavities, examining areas such as parasitic effects in vacuum electronics systems such as Multipactor discharges and, the effect each stage in the manufacturing process of RF cavities has upon cavity performance and manufacturing reproducibility. In this work we examine how the surface topology and chemistry changes as the material is processed, how these changes occur and how they result in breakdown.

I am also examining new techniques to develop thin superconducting (SC) films for RF accelerator technology, both at 2K and 77K via the application of the proximity effect to develop SC technologies for resonant cavities. This work could have a major impact on future developments at the ESS, and is funded via the FP7 programme EUCard and the UK research council STFC.

Recently I have started to consider the role of accelerator reliability for Accelerator driven subcritical reactor (ADSR) applications, examining the reliability required for the accelerator to make ADSRs a viable technology option. I am looking to expand this work to examine the use of reliability studies to inform the design process of accelerators.
