Abstract
SINBAD (Short and INnovative Bunches and Accelerators at DESY) facility will host multiple experiments relating to ultra-short high brightness beams and novel experiments with ultra-high gradient. ARES (Accelerator Research Experiment at SINBAD) Linac is an S-band photo injector to produce such electron bunches at around 100 MeV. The Linac will be commissioned in stages with the first stage corresponding to gun commissioning. In this paper, we present studies about the scheme adopted for the alignment of focusing solenoid for the ARES gun. The method is bench marked using ASTRA simulations. Moreover the effect of misalignment of the solenoid on the emittance of space charge dominated scheme and its compensation is also discussed.
Highlights
The goal of SINBAD (Short INnovative Bunches and Accelerators at DESY), a dedicated accelerator R&D facility at DESY, is to study ultra-fast physics and perform novel acceleration technique experiments [1,2,3]
The alignment model is based on the transfer matrices and assumes that there is no overlap of the magnetic field “B” of the solenoids with the electro-magnetic “E” field of the RF gun
We have introduced in the input lattice-file in ASTRA, a misalignment of the solenoid with respect to the beam trajectory
