Evaluation of a terahertz camera system for imaging, tomographic and diagnostic measurements at KARA — •André Schmidt¹, Stefan Funkner¹, Gudrun Niehues¹, Erik Bründermann¹, and Anke-Susanne Müller^{1, 2} — ¹IBPT, KIT, Karlsruhe — ²LAS, KIT, Karlsruhe

With a short bunch operation mode, the KIT electron storage ring KARA (Karlsruhe Research Accelerator) features the creation of the so-called microbunching instability, which emits bright bursts of THz radiation.

The creation of an instability provides the opportunity to study complex beams dynamics by the investigation of properties from the emitted radiation. Furthermore, the emission of bright THz radiation bears the potential for many research applications in photon science.

In this contribution, we present an evaluation of a microbolometer-based THz-camera system, which is able to operate at 50 frames/s. In this regard, first results from tomographic measurements with a standalone THz illumination source and results from diagnostic beam measurements during the short bunch operation mode at KARA are shown.
