The Project of complete modernization of a current accelerator complex and the making of the 3-d generation light source is in progress in the NRC «Kurchatov Institute». A new booster synchrotron is part of the injection complex for a new synchrotron light source. It must ensure reliable and stable operation of the upgraded main storage ring. The paper presents the lattice of a new booster synchrotron and its main parameters.

New linear electron accelerator (linac) with an energy of about 200 MeV (or 300 MeV in a high-energy version) is being proposed for injection into the booster synchrotron, which is being developed for the reconstruction of the SIBERIA-2 accelerator complex with the aim of upgrade to 3rd generation source at the NRC «Kurchatov Institute». A modernized linac and its specific elements layout will described in the report. The modeling of accelerating structure and optimization of electrodynamics characteristics and fields distribution and geometric in order to reduce the beam spectrum at the output of the linac was done. A step-by-step front-to-end beam dynamics simulation results will discuss.

We developed a hybrid optical pump–x-ray probe facility based on the “Kurchatov’s synchrotron radiation source” and terawatt (TW) femtosecond laser. The bright x-ray photon source is based on either synchrotron radiation [up to 6 × 10¹⁴ photons/(s mm² mrad² 0.1% bandwidth)] or laser-plasma generators (up to 10⁸ photons/sr/pulse). The terawatt (TW) femtosecond laser pulse initiated phase transitions and a non-stationary “extreme” state of matter, while the delayed x-ray pulse acts as a probe. The synchronization between synchrotron radiation and laser pulses is achieved at 60.3 MHz using an intelligent field-programmable gate array-based phased locked loop. The timing jitter of the system is less than 30 ps. In laser-plasma sources, the x-ray and laser pulses are automatically synchronized because they are produced by using the same laser source (TW laser system). We have reached an x-ray yield of about 10⁶ photons/sr/pulse with 6-mJ sub-ps laser pulses and using helium as a local gas medium. Under vacuum conditions, the laser energy increase up to 40 mJ leads to the enhancement of the x-ray yield of up to 10⁸ photons/sr/pulse. The developed hybrid facility paves the way for a new class of time-resolved x-ray optical pump–probe experiments in the time interval from femtoseconds to microseconds and the energy spectrum from 3 to 30 keV.

Work on the conceptual design of a dedicated fourth-generation fourth-generation Specialized Synchrotron Radiation Source (SSRS-4) is in progress at the Kurchatov Institute, Moscow. The project is being developed in collaboration with the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. In this paper, the initial results of our work on this project are reported, major directions of current research are presented, and possible areas of application of the SSRS-4 are outlined. The key element of the currently discussed design is a 6-GeV storage synchrotron with an orbit length of ~1300 m and the magnetic lattice that should provide a horizontal transverse emission of 70–100 pm rad. Further optimization may allow for reducing the emittance to 20–40 pm rad. Of the injection schemes under discussion, one features a full-scale booster synchrotron deployed in the same tunnel as the main storage ring, and the second is a topup linac. The latter can also be used as an electron-beam driver for a free-electron laser.

... The X-ray-optical experiments took place at the "RKFM" beamline, dedicated to X-ray crystallography and physical materials science, within the Kurchatov Synchrotron Radiation Source "KISI-Kurchatov". The successful implementation of synchronization techniques at the "Phase" beamline has expanded the capabilities in experiments at the RKFM beamline [25]. The RKFM beamline gives an opportunity to decrease the diameter of the X-ray beam on the sample up to several micrometers. ...

... Moreover, depending on the amplitude and time duration of loading, the final phase of Si is varied from amorphous to Ibam, BC8, hex. diamond (Si-IX), etc. [13,14]. The presumptive tree of phase transitions in Si primarily depends on the velocity of pressure release and do not take into account the role of temperature that would probably arise in the experiments, both in the case of laser ablation (when the laser pulse is directly focused onto the sample's surface [15,16]) or shock-wave impact. ...

... Synchrotron radiation sources stand out as one of the most practical X-ray radiation sources for investigating phenomena occurring on the timescale from hundreds of picoseconds up to milliseconds. Leveraging laser-synchrotron complexes [26] enables precise time-resolved measurements with subnanosecond resolution and the acquisition of high-quality statistical data. In this study, the approach outlined in [26] was optimized to perform time-resolved X-ray diffraction analyses of the deformation dynamics of nominally pure LiNbO 3 and LiNbO 3 :Fe at a synchrotron radiation (SR) source under nanosecond laser impact. ...

... While works featuring GA-based MOO algorithms for the optimization of accelerator systems do appear in the literature [33][34][35][36][37][38], the application of such optimization algorithms to accelerator magnet design seems to have been so far neglected. In fact, the only relevant work that the authors are aware of is [1], which mentions the option of optimizing accelerator magnets by means of MOO based on GAs, however, without providing any verification in the form of numerical experiments. ...

Such a profilometer is currently operating at the OOS station [6,7] of the Kurchatov Synchrotron Radiation Source [8], where the typical measurable value of the vertical beam size at the emitting point used to output the light is μm. ...
