The members of the group have expertise in
theoretical and experimental investigations of beam dynamics of
photoinjectors, light sources and lepton colliders. The group has
specialisation in other unique areas such as photocathode physics, low
emittance tuning and collimation designs, all skills required for future
challenging high brightness applications. This Group has been concentrating mainly on high brightness electron beams (eg for linear colliders and light sources) including the design and operation of high performance electron guns.
At Daresbury Laboratory, the group is responsible for design and commissioning of ALICE
(Accelerators and Lasers In Combined Experiments), a 35 MeV
superconducting energy recovery linac which drives an infra-red Free
Electron Laser (FEL) as well as coherant THz radiation.
ALICE also feeds beam into EMMA
(Electron Machine of Many Applications), the world's first non-scaling
FFAG (Fixed Field Alternating Gradient) accelerator. In 2011, this
proof-of-principle machine validated the science behind this new type of
particle accelerator, leading the way for future projects in the areas
of cancer therapy, safer nuclear reactors, and muon accelerators.
The group has designed the EBTF
(Electron Beam Test Facility), a high performance photo-injector, utilising space in the ex-SRS outer hall, and is designing CLARA
, a future FEL test facility. Photoinjector and photocathode research
to deliver and manipulate ultra high brightness beams is one of the major research areas that the group is dealing with.
The accelerator physics group has made significant contributions to light source design in the UK, from Diamond
through to the 4GLS
projects. With expertise from range of these challenging projects, the group has made unique contributions to the MAX IV
injector design and tolerance studies and collimation performance studies for SwissFEL
The members of the group are contributing to the beam dynamics of HiLumi LHC
