Many single-shot recording setups are based on the encoding of the information onto a laser pulse. This concerns in particular electro-optic sampling of bunch shapes, and VUV/X pulse monitors using transient reflectivity. The upgrade of these methods to high repetition rates presents challenging issues, that are due to the limited speed of the recording cameras. Recently [1], we demonstrated that multi-MHz repetition rates can be achieved using a relatively simple upgrade of existing setups, using the so-called "photonic time-stretch" technique. Here we present guidelines for the practical realization in the case of electro-optic sampling. We also present a performance analysis, and compare it to the spectral encoding case. The technique is potentially applicable to other cases where the information can be encoded on a chirped laser pulse, as, e.g., transient reflectivity diagnostics of XUV pulses.

LUNEX5 (free electron Laser Using a New accelerator for the Exploitation of X-ray radiation of 5th generation) aims at investigating compact and advanced Free Electron Laser (FEL). It comprises one one hand a 400 MeV superconducting linac for studies of advanced FEL schemes, high repetition rate operation (10 kHz), multi-FEL lines, and one the other hand a Laser Wake Field Accelerator (LWFA) for its qualification by a FEL application, an undulator line enabling advanced seeding and pilot user applications in the 40-4 nm spectral range. Following the CDR completion, different R&D programs were launched, as for instance on FEL pulse duration measurement, high repetition rate electro-optical sampling. The COXINEL ERC Advanced Grant aims at demonstrating LWFA based FEL amplification, thanks to a proper electron beam manipulation, with a test experiment under preparation. As a specific hardware is also under development such as a cryo-ready 3 m long undulator of 15 mm period is under development.
