Design studies for final focus system for laser wake field acceleration experiment at SINBAD facility at DESY — •Sumera Yamin, Ralph W Assmann, Florian Burkart, Francois Lemery, Barbara Marchetti, Eva Panofski, and Paul A Walker — Deutsches Elektronen Synchtron, DESY, Notkestrasse 85, 22607, Hamburg, Germany

The ARES (Accelerator Research experiment at SINBAD) Linac at SINBAD (Short and INnovative Bunches and Accelerators at DESY) facility at DESY aims to produce high brightness ultrashort electron bunches (sub fs to few fs) at around 100 MeV, suitable for injection into novel accelerators such as dielectric Laser acceleration (DLA) and Laser Wake Field Acceleration (LWFA). The LWFA Experiment with external injection planned at ARES aims towards studies for stable LWFA by combining the reproducible and stable RF based- accelerator technology with high gradient plasma wake field dynamics. One of the possible configurations, which is currently under consideration, for the injection in the plasma experiment requires the Twiss parameter β to be of the order of few mm at the injection point. The effect of space charge for high density electron bunches, such the ones produces at ARES with bunch charge of up to 10 pC and bunch length from sub fs to few fs, is dominant in the matching region. With the co-propagating Laser and electron beam in the external injection experiment, there are a lot of technical constraints that has to be considered for the final design. We aim to present design studies for the final focus system for LWFA experiment planned at ARES.
