Exploring the limits of spatiotemporal diagnostics of electron accelerators, light sources and lasers

Kolloquium der Abteilung 7

Modern accelerators and lasers require a multitude of diagnostic and synchronization techniques to measure energy, frequency, spectral coverage, ultra-short pulses, spatial profiles, electric and magnetic field distributions to enable reliable, stable, and reproducible operation and control. At KIT the Institute for Beam Physics and Technology (IBPT) operates the synchrotron radiation source ANKA (Ångströmquelle Karlsruhe) as a dedicated test-facility to explore electron beams and short bunches emitting photons covering nearly the whole electromagnetic spectrum from the terahertz (THz) range to hard X-rays. Thus, sensitive, often broadband detectors, imaging and microscopy systems are needed. In addition, fast detectors and sensors to unravel ps and sub-ps dynamics of the electron bunches, e.g. by electro-optical spectral decoding using near-field effects, ideally in single-shot mode at high-repetition rates in the GHz range are desired. At a data acquisition rate of TByte/h, handling of large amounts of data is also an issue. IBPT also builds up the linear accelerator-based FLUTE (Ferninfrarot Linac- Und Test Experiment) for ultra-short and high intensity pulses projected for fs and shorter pulses, corresponding to frequency coverage of 100 THz and beyond, high peak powers of GW, and GV/m electric fields for electron-photon interaction and non-linear studies. The task of the department of accelerator research is to explore and adapt available or to develop new techniques for advanced spatiotemporal diagnostics considering timing and synchronization. The presentation will review recent progress to answer questions of the diagnostics wish list.
