“…Its goals are to demonstrate the generation and acceleration of ultrashort electron bunches, and to test advanced acceleration techniques such as laser driven plasma wake-field acceleration (LWFA), dielectric laser acceleration (DLA) and THz-driven acceleration, in multiple independent experiments. ARES (Accelerator Research Experiment at SINBAD) [2,3] at SINBAD represents one of these experiments. The linear RF accelerator with a target energy of 100-155 MeV is currently in the construction and commissioning phase.…”

Over the years, the generation and acceleration of ultra-short, high quality electron beams has attracted more and more interest in accelerator science. Electron bunches with these properties are necessary to operate and test novel diagnostics and advanced high-gradient accelerating schemes, such as plasma accelerators and dielectric laser accelerators. Furthermore, several medical and industrial applications require high-brightness electron beams. The dedicated R&D facility ARES at DESY (Deutsches Elektronen-Synchrotron) will provide such probe beams in the upcoming years. After the setup of the normal-conducting, radio-frequency (RF) photoinjector and linear accelerating structures, ARES successfully started the beam commissioning of the RF gun. This paper gives an overview of the ARES photoinjector setup and summarizes the results of the gun commissioning process. The quality of the first electron beams is characterized in terms of charge, momentum, momentum spread and beam size. Additionally, the dependencies of the beam parameters on RF settings are described. All measurement results of the characterized beams fulfill the requirements for operating the ARES linac with this RF photoinjector.

“…The main beam parameters are summarized in Table 1. The ARES linac consists of a 5 MeV RF gun followed by two travelling wave structures (TWS) with space reserved for a third travelling wave structure for a possible future energy upgrade [7]. This space will be temporarily used as first experimental area (EA).…”

“…It includes research in the field of ultrashort electron bunches and will host multiple independent experiments [2] on laser driven advanced high gradient acceleration techniques such as Dielectric Laser Acceleration (DLA) [3], Laser Plasma Acceleration (LPA) [4] and THz-driven acceleration in the AX-SIS project [5]. The ARES (Accelerator Research Experiment at SINBAD) linear accelerator (linac) at SIN-BAD is based on conventional S-band technology with a photo-injector gun [6] [7]. It is designed to provide ultrashort high brightness electron beams for injection into novel accelerators.…”

“…bunch shape, bunch length, emittance, arrival time stability and beam energy. ARES provides the option of widely tunable working points (WP) and bunch shapes for external injection LPA accelerator R&D. External injection of electron beam into an LPA, however, has its own technical challenges [7]. The synchronization of laser and electron beam can be the most crucial aspect of this experiment.…”

combine reproducible beams from conventional RF-based accelerator technology with novel but still experimental acceleration techniques. It aims to produce high brightness ultra-short electron bunches in the range of sub fs to few fs, at a beam energy of 100-150 MeV, suitable for injection into novel acceleration experiments like Dielectric Laser Acceleration (DLA) and Laser driven Plasma Acceleration (LPA). This paper reports the conceptual design and simulations of a final focus system for injecting into a LPA experiment at ARES, including permanent magnetic quadrupoles (PMQ), sufficient longitudinal space for collinear laser and electron transport, space for required diagnostics and a LPA setup. Space-charge effects play a significant role and are included. Simulation results on the focusing of the ARES electron bunches into and their transport through the laser-driven plasma are presented. The effects of several errors have been simulated and are reported.
