The machine is an assembly of components used to produce, confine and maintain a high energy electron beam in a closed orbit for periods of several hours while the electrons produce synchrotron light for a wide variety of experiments.
Electrons with an energy of 0.1 GeV are injected from the linac into the booster synchrotron. Here the electrons follow an “athletics track” shaped trajectory with two straight sections joined together with semicircular curves. Thirty six dipole bending magnets are used to curve the electrons around the bends. A radio frequency voltage source is used to accelerate the electrons in the straight sections. To maintain a fixed radius of curvature, the magnetic field produced by the bending magnets is increased (up to a maximum of 0.8 Tesla) as the electron energy rises up to a final extraction energy of 3 GeV.
Diamond Light Source is the UK's national synchrotron science facility, located at the Harwell Science and Innovation Campus in Oxfordshire.
