Description

FLUTE (Ferninfrarot Linac- Und Test-Experiment) is a compact linac-based test
facility for accelerator and diagnostics R&D. An example for a new accelerator
diagnostics tool currently studied at FLUTE is the split-ring-resonator (SRR)
experiment, which aims to measure the longitudinal bunch profile of fs-scale
electron bunches. Laser-generated THz radiation is used to excite a high
frequency oscillating electromagnetic field in the SRR. Particles passing
through the SRR gap are time-dependently deflected in the vertical plane,
which allows a vertical streaking of an electron bunch. This principle allows a
diagnosis of the longitudinal bunch profile in the femtosecond time domain
and will be tested at FLUTE. This contribution presents an overview of the
SRR experiment and the results of various tracking simulations for different
scenarios as a function of laser pulse length and bunch charge. Based on
these results possible working points for the experiments at FLUTE will be
proposed.
