Accelerator Physics
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 accelerator physics group have expertise in design, beam dynamics studies and operation of a range of electron accelerators. Since ASTeC was formed the accelerator physics group has contributed to a large number of projects includingtest, large international particle physics projects, synchrotron radiation sources, free electron lasers, novel accelerator science projects, and commercial and industrial projects. The group have performed a wide range of tasks on these projects and have skills and experience through the entire life cycle of accelerator design and operation. These tasks include: design and simulations of beam generation, acceleration and  transport starting from electron sources and injectors through accelerator structures and beam delivery lines to final beam users (such as FELs and others); construction and experimental commissioning of entire machines and their components both in the UK and abroad; scientific studies of beam properties and accelerator physics topics; scientific support and delivery of commercial accelerator facilities.​

At present, a principal focus of the accelerator physics group is the design, commissioning and operation of the VELA (Versatile Electron Linear Accelerator) and CLARA (Compact Linear Accelerator for Research and Applications) at STFC Daresbury Laboratory.

Key Project Areas of the group:

-Accelerator Physics design of VELA, CLARA and future UK X-FEL facility.​

-Research and development of advanced electron sources including photocathode science and technology​, design/development of DC and RF photoinjectors in collaboration with the Vacuum and RF groups.

-Scientific studies of the physics of accelerated beams in both experiments and simulations, on collective effects such as cathode physics, beam non-uniformities, recirculating machine design, longitudinal transport and bunch compression.

-​Contributions to accelerator commissioning of SwissFEL and FERMI@Elettra.

Legacy Projects and Achievements:

-Accelerator physics design and commissioning of the ALICE machine, Europe's first free electron laser driven by an energy recovery accelerator (and the UK's first free electron laser).​

-Accelerator physics design and commissioning, operation and study of EMMA the novel acceleration machine at STFC Daresbury laboratory – the first machine of its kind in the world.

-Design of the accelerator physics of past, present and future UK light source projects including DIAMOND light source, 4GLS (4th Generation Light Source) and NLS (New Light Source).

-Contributions to the design of large international projects including the International Linear Collider, Collimation for the SwissFEL, and the Max IV Linac.

-Contributions to accelerator commissioning worldwide including the Accelerator Test Facility (ATF2) in Japan, the End Station A at the Stanford Linear Acce​lerator, High Luminosity LHC experiments at CERN.
