Longitudinal and Transverse Beam Diagnostic using Synchrotron Radiation at ALBA

Synchrotron Light Sources are usually user-oriented facilities, for this reason it is necessary to ensure a high reliability of the machine, for which a constant and on-line monitoring of the particle beam is mandatory. The synchrotron radiation produced by the beam can be used to develop non-invasive diagnostics tools to perform measurements of both longitudinal and transverse electron distributions. In this thesis, techniques used and developed at ALBA Synchrotron Light Source in the last years and their applications are presented. The setup of Time Correlated Single Photon Counting for filling pattern measurements, using both visible light and x-rays, together with its applications in the development of new machines operation modes are presented. Moreover the commissioning of the Synchrotron Radiation Interferometry (SRI) and its basic application to measure the horizontal and vertical beam sizes are introduced, together with further developments aided to improve the standard SRI resolution and to open new possibilities such as measurements at low current or bunch by bunch.
