	Funding: Work supported by DFG, BMBF, FZ Jülich, and by the Federal State NRW. The 1.5-GeV synchrotron light source DELTA, operated by the TU Dortmund University, comprises a short-pulse facility based on the coherent harmonic generation (CHG) technique, which allows for the generation of radiation pulses with wavelengths down to 50 nm and a duration of 50 fs. In order to reach even shorter wavelengths, the present setup will be modified to employ the echo-enabled harmonic generation (EEHG) and femtoslicing techniques. In this paper, recent developments including an improved lattice design and a concept for the new vacuum chambers will be presented.

TUP014	Beam Commissioning and Initial Measurements on the MAX IV 3 GeV Linac	linac, gun, sextupole, electron	375

	The linear accelerator at the MAX IV facility in Lund, Sweden, was constructed for injection and top up of the two storage rings and as a high brightness driver for the Short Pulse Facility. It is also prepared to be used as an injector for a possible future Free Electron Laser. Installation of the linac was completed and beam commissioning started in the early fall of 2014. In this paper we present the progress during the first phase of commissioning along with results from initial measurements of optics, emittance, beam energy and charge.

Many single-shot recording setups are based on the encoding of the information onto a laser pulse.

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.
