Perhaps one of the most crucial diagnostic targets in the operation of accelerator facilities is the phase space density (PSD) of the accelerated particle bunches. The knowledge of the PSD not only governs the emission spectrum of the bunches, but it also determines other fundamental properties such as bunch length, energy spread, and more sophisticated, intra-bunch interactions. Importantly,...
Besides the classical Feschenko monitor also Fast Faraday Cups (FFC) and GHz Transition Radiation monitors (GTR) are able to measure the longitudinal bunch shape. While the Feschenko monitor observes an averaged bunch shape, both latter devices can measure the shape bunch by bunch within a bunch train. In this contribution we want to show the current research at GSI ion LINAC on FFCs and GTRs...
Regulating the arrival time of electron bunches is a crucial step to improve the temporal resolution of accelerator-based time-resolved experiments. Nowadays, a regulation method, called beam-based feedback, has been shown to work well for stabilizing the arrival time on pulsed accelerator machines. Essentially, this method resembles a typical design of a simple proportional regulator, where...
During the last decades, the precision of the measurement of length variations has increased drastically to reach the nanometer scale, or a sub-femtosecond timescale, based on transit time-stabilized optical fibers using femtosecond laser pulses. Thanks to the high precision of the stabilization system, the influence of different perturbations can be investigated, such as environmental changes...
