Beam diagnostics systems are essential constituents of any particle accelerator; they reveal the properties of a beam and how it behaves in a machine. Without an appropriate set of diagnostic elements, it would simply be impossible to operate any accelerator complex let alone optimise its performance. The QUASAR Group led the largest-ever training initiative in beam instrumentation, DITANET. Presently, the group carries out research into beam loss monitors, propagation and monitoring of beam halo, absolute beam current measurements, the exploitation of synchrotron radiation for beam profile measurements, gas jet-based beam profile monitors, very high resolution OTR, beam instrumentation for exotic ion beams and detectors for pulsed neutron beams. These activities are linked to developments within the EU projects LA³NET and oPAC.
In this seminar I will give an overview of our research activities in beam diagnostics, present results from numerical and experimental studies and give an outlook on our future R&D plans.
