Development of a Beam Halo Monitor using Visible Synchrotron Radiation

To create the powerful beams of synchrotron light used at Diamond, electrons are accelerated to nearly the speed of light in a narrow circular pipe called the storage ring. Beam halo describes the electrons that circulate around the storage ring of the accelerator which are offset from the main beam. With the planned upgrade of the accelerator to Diamond-II, it is already known that the beam pipe in the new storage ring will be significantly reduced in size. Thus, it is important to improve our understanding of the transverse size of the beam halo around the stored electron beam.

To achieve this goal, a new beam halo monitor will be developed for operation on the storage ring. This monitor will be an optical system which uses visible synchrotron radiation (i.e. photons emitted by the electron beam). With this optical system, images of the beam halo around the stored beam will be acquired and analysed.
