“…Being part of the ACHIP collaboration DESY will conduct related test experiments at its SINBAD facility [1]. Here we present plans for the first DLA experiments at SINBAD using electrons produced by the ARES linac [2,3]. In addition to the conceptual layout of the experiment we present possible linac working points and an estimation of the expected results using a β-matched dual grating type DLA structure [4] illuminated by a 1 or 2 micron laser.…”

In this work we present the outlines of possible experiments for dielectric laser acceleration (DLA) of ultra-short relativistic electron bunches produced by the ARES linac, currently under construction at the SINBAD facility (DESY Hamburg). The experiments are to be performed as part of the Accelerator on a Chip International Program (ACHIP), funded by the Gordon and Betty Moore Foundation. At SINBAD we plan to test the acceleration of already preaccelerated relativistic electron bunches in laser-illuminated dielectric grating structures. We present outlines of both the acceleration of ultra-short single bunches, as well as the option to accelerate phase-synchronous sub-fs microbunch trains. Here the electron bunch is conditioned prior to the injection by interaction with an external laser field in an undulator. This generates a sinusoidal energy modulation that is transformed into periodic microbunches in a subsequent chicane. The phase synchronization is achieved by driving both the modulation process and the DLA with the same laser pulse. In addition to the conceptual layouts and plans of the experiments we present start-to-end simulation results for different ARES working points.

“…The ARES linac, currently under construction at DESY, will form an integral part of the SINBAD R&D facility [1]. Using S-band travelling wave structures, it will be capable of producing sub-femtosecond electron bunches with energies of up to 100 MeV and an arrival time stability of 10 fs [2,3]. These bunches will be optimized for injection into novel accelerating structures, such as dielectric laser acceleration (DLA) structures [4,5] and plasma cells for laser-driven plasma wakefield acceleration (LPWA) [6].…”

A transverse deflecting structure (TDS) is a well-known device for characterizing the longitudinal properties of an electron bunch in a linear accelerator. The standard use of such a cavity involves streaking the bunch along a transverse axis and analysing the image on a screen downstream to find the bunch length and slice properties along the other transverse axis. A novel X-band deflecting structure, which will allow the polarization of the deflecting field to be adjusted, is currently being designed as part of a collaboration between CERN, DESY and PSI. This new design will allow bunches to be streaked at any transverse angle within the cavity, which will open up the possibility of new measurement techniques, which could be combined to characterize the 6D phase space distribution of bunches. In this paper, a method is presented for reconstructing the longitudinal phase space distribution of bunches by using the TDS in combination with a dipole. Simulations of this technique for the SINBAD-ARES beamline are presented and the key limitations related to temporal resolution and induced energy spread are discussed.
