KALYPSO is a 1D detector fully coupled with an Electro-Optical beam profile measurement for a sub-ps resolution at ANKA and Eu-XFEL. A recent update of the KALYPSO project will be presented. Several ongoing developments have been started to improve the performance in term of femtosecond time accuracy, noise and higher frame-rate. A custom front-end Application Specific Integrated Circuit...

The usage of a fast-gated intensified camera (FGC) allows to study the horizontal bunch size and thus the energy spread on a single turn base. At the ANKA storage ring such a camera is embedded into a synchronisation scheme for the synchronous detection of the horizontal bunch size, the CSR intensity as well as the longitudinal bunch profile. Here we present the result of these studies with...

The micro-bunching instability causes the formation of time-varying sub-structures in the longitudinal phase space leading to fluctuations and strong bursts in the observed coherent synchrotron radiation (CSR) in the terahertz (THz) frequency range. These fluctuations can be detected simultaneously for each individual bunch in a multi-bunch environment using fast THz detectors combined with...

The longitudinal current profile and slice emittance are important bunch parameters for the operation of an X-ray free-electron laser. At the European XFEL, dedicated diagnostic sections equipped with transverse deflecting RF structures (TDS) have been installed for the control and optimisation of these parameters. Travelling-wave TDS in combination with fast kicker magnets and off-axis...

A novel on-chip spectrometer based on arrays of Schottky diodes has been developed. Showing promising results in a first experiment at TELBE (operation at room temperature, excellent signal-to-noise ratio up to MHz repetition rates, sufficient spectral filtering), optimized versions have been developed aiming at better frequency resolution and lower crosstalk between the frequency resolved...

The Photo Injector Test facility at DESY, Zeuthen site (PITZ) develops high brightness electron sources for modern linac-based Free Electron Lasers (FELs). A precise measurement of electron beam (e-beam) charge is essential. Several Faraday Cups (FCs) and Integrating Current Transformers (ICTs) are installed along the PITZ beamline to measure the e-beam charge. In order to improve the accuracy...
