Abstract

At the SINBAD facility (DESY Hamburg), novel particle acceleration techniques like dielectric laser acceleration (DLA) structures will be tested using the ARES linac. Due to the small size of these structures, the accelerated electron beams only have a very low (sub-pC) charge. To determine the energy distribution of these beams, a silicon strip detector for the ARES linac spectrometer is currently under development. This detector fulfils the requirements of high spatial resolution for low charge density beams. The detector consists of two 1 cm × 1 cm silicon strip sensors and readout components. The design of the detector, its components and an estimate of its behaviour for a specific electron beam distribution are presented and discussed.

Highlights

SINBAD (Short and INovative Bunches and Accelerators at Desy) [1] is a dedicated accelerator R&D facility at DESY hosting ARES (Accelerator Research Experiment at Sinbad) [2], a 100 MeV S-band electron linac which is currently under commissioning
The ARES linac is designed to test novel acceleration techniques, such as plasma acceleration or dielectric laser acceleration (DLA), which are characterized by small apertures and acceleration periods
ARES aims at delivering electron beams with unique properties such as ultra short bunches with fs to sub-fs duration and low charges (0.3 - 30 pC) [1] with an arrival time jitter of ∼ 10 fs [3]

Summary

INTRODUCTION

SINBAD (Short and INovative Bunches and Accelerators at Desy) [1] is a dedicated accelerator R&D facility at DESY hosting ARES (Accelerator Research Experiment at Sinbad) [2], a 100 MeV S-band electron linac which is currently under commissioning. ARES aims at delivering electron beams with unique properties such as ultra short bunches with fs to sub-fs duration and low charges (0.3 - 30 pC) [1] with an arrival time jitter of ∼ 10 fs [3]. It will run in single bunch mode with a repetition rate up to 50 Hz [1]. ACHIP foresees to use dual grating type DLA structures to accelerate electrons produced at the ARES linac. The electron distribution in x and y dimensions at the position of the detector for the 0.5 pC case as well as the number of electrons integrated over the whole y range and the corresponding charge of the electron spectrum at a certain x
