Accelerator Physics Group
22 Mar 2010



The Accelerator Physics Group, led by Deepa Angal-Kalinin, is able to model the behaviour of charged particle beams in accelerators and transport systems, including aspects of nonlinear beam dynamics.



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 and NLS 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 design studies.
