|
|||
| The system of particles collimation developed for the NICA collider is considered. The main collimation goal is the beam halo cleaning to minimize the background for experiment. The main mechanisms of particle losses, including the ion recombination in electron cooler, are also reviewed. | |||

| TUPSB28 | X-ray Thomson Inverse Scattering from Periodically Modulated Laser Pulses | laser, electron, radiation, HOM | 283 |
|
|||
|
Funding: This work is performed within the project supported by the Russian Foundation for Basic Research (RFBR), grant # 19-29-12036 Being a compact source of x-rays based on the Thomson backscattering Thomson source has potential to be used in medicine and biology and in other area where narrow band x-ray beams are essential. We suggest and investigate theoretically the idea to use laser pulses modulated with a short period in Thomson backscattering. The coherent radiation is obtained with intensity proportional to the squared number of micro-pulses in the whole laser pulse. |

| TUPSB29 | Geant4 for Inverse Compton Radiation Source Simulations | electron, laser, photon, radiation | 286 |

Funding: This work was supported by the RFBR grant 19-29-12036. Compton backscattering* is a promising mechanism for engineering of a bright, compact and versatile X-ray source: with dimensions being significantly smaller, the brightness of this source is comparable with that of synchrotron radiation. Nowadays, active researches are underway on various aspects of this phenomenon** aiming at increasing of radiation intensity and quality. In modern science, such kind of research is necessarily accompanied by the computer simulations. In this report, we are talking about creation and implementation of the Compton backscattering module into the Geant4 package***, which is the leading simulation toolkit in high-energy physics, accelerator physics, medical physics, and space studies. Created module of Compton backscattering has been implemented as a discrete physical process and operates with a fixed light target (a virtual volume with the properties of a laser beam), with which a beam of charged particles interacts. Such a description allows user to flexibly change necessary parameters depending on the problem being solved, which opens up new possibilities for using Geant4 in the studied area. * K.T.
