The aim of the work is to develop a method of ensuring a stable intensity of collisions of the beam with the nuclei of a fixed solid-state target by correcting the position of the target in the halo of the beam by a microstep engine. Investigation of the influence of the work of the internal target on the lifetime of the proton beam in the LHC collider. Participation in the development of technical design of the target node, which uses ultra-thin target, and a very light mechanical design with an accuracy of 0.1 μm and instantaneous (milliseconds) response. A method for achieving a stable intensity of collisions of the beam with the nuclei of a fixed solid-state target by correcting the position of the target in the beam halo by a micro-step motor with feedback control is proposed. A formalism for describing the reduction of beam intensity under the influence of various factors has been developed. For a better understanding of various aspects of the fixed target, analytical calculations and modeling by Monte Carlo methods of the impact of the internal target on the lifetime of the proton beam VAC. In addition, the technical design of the target unit, which uses ultra-thin targets, was developed in close cooperation with the Institute of Nuclear Research of the National Academy of Sciences of Ukraine. At the same time, we also conducted experiments on e + e-beams to study the decay of particles with b and c quarks in given channels, which is necessary to search for extreme states of matter by comparing these decays in the nuclear environment.  Product Description popup.authors popup.nrat_date 2022-03-09 Close
