New magnetized high energy coolers as well as Energy Recovery Linacs have a beam power in the order of several megawatts without having highly relativistic beams. This makes the commonly used diagnostic tools such as synchrotron radiation quite ineff ective. The goal of new diagnostic methods is to minimize the interaction of the diagnostic devices with the beam in order to prevent the devices as well as the beam from being destroyed. For beam profile measurements, a system based on beam induced fluorescence (BIF)was designed. Furthermore the Thomson Laser Scanner (TLS) - the non-relativistic version of the Laser Wire Scanner - is proposed as a method for non-invasive measurement of all phase space components, especially in the injector and merger parts of an ERL. In order to prove the feasibility of these methods and their application in existing systems, first tests are being carried out at our polarized test source (PKAT), after which we aim to integrate both diagnostics devices with our HESR electron cooler test bench. First beam profile measurements with BIF as well as the implementation of the TLS will be presented.
