At present, a fourth-generation synchrotron radiation source USSR (Synchrotron & Laser), which will the one of
the world's largest scientific centers is being designed in Russia. Its creation will make it possible to carry out
experiments to study the structures of a wide range of objects in various disciplines at a qualitatively new level
compared to the previous generation of sources. The overall facility layout includes a 6 GeV main storage ring
and a linear electron accelerator (linac) at full energy. It is proposed to use one linear accelerator with two RF
guns. A RF gun with a photocathode can be used to generate a bunch train for a Free Electron Laser (FEL), a
RF gun with a thermionic cathode can be used for injection into a storage ring. Both injectors will operate with
the same regular part of the linear accelerator, consisting of 100-120 identical sections. The purposed transverse
emittance in the main storage ring will be 50–100 pm.rad. The development of a general linear accelerator
scheme in order to minimize the beam energy spread and the output transverse emittance, the optimization of
the geometric and electrodynamics parameters of the accelerating structures, and the beam dynamics analysis in
this linear accelerator will be discussed in the article. The beam dynamics simulation was performed using the
BEAMDULAC code developed at the Department of Electrophysical Facilities of the National Research Nuclear
University MEPhI.
