This radiation is a re alisation of cuspoid catastrophes in electromagnetic radiation. The radiat ion can be generated at the non-constant motion of a charged particle in a transparent medium and is emitted at a very narrow solid angle. The radia tion is more intensive than ordinary VChR and is generated only at specifi c angles\, that depend uniquely on the particle's motion in the medium. Fo r this reason\, it could be used to measure particle parameters that deter mine the motion of a charged particle\, such as momentum and charge. The m omenta of charged particles are usually determined in magnetic spectromete rs. The Lorentz force causes the particles to follow circular or helical t rajectories around the direction of the magnetic field. The bending radius R of particle tracks is related to the magnetic field strength and the mo mentum component of the particle perpendicular to the magnetic field ptran s. With a suitably focusing optical system\, this allows the reconstructio n arc of a ring. In a focusing detector\, the photons can be collected by a spherical mirror with focal length f and focused onto the photon detecto r placed at the focal plane. The result is an arc of the circle with a rad ius r\, independent of the emission point along the particle's track. The main goal of this work is to study the cuspoid radiation emitted by a char ge when it moves in a magnetic field and its application in high-energy ph ysics and neutrino physics. If we use the ring-imaging detection technique \, then we can measure the following parameters using cuspoid radiation: r adius r of the arc of the ring (r is directly related to ptrans)\, deflect ion angle ψ\, azimuthal angle φ\, polar angle θ and the number of emitt ed photons Ncusp. With the help of these parameters\, it is\, in principle \, also possible to determine the position of the vertex\, the origin of p article track in the magnetic field. Cuspoid radiation could be an alterna tive for measuring the momentum of relativistic particles and improve the possibilities of their identification. In many cases\, measuring only elec tromagnetic radiation (Cherenkov\, cuspoid) will be sufficient to identify a charged particle. Due to the large penetrating power of muons in materi als\, the influence of multiple scattering on its trajectory in a transpar ent medium placed in a magnetic field can be neglected. Muon detection is an important aspect of neutrino physics and\, therefore\, in our opinion\, measuring the muon momentum using the cuspoid radiation method can be of significant help in experiments aimed at investigating the properties of n eutrino. The advantage is that the same Ring Imaging Cherenkov detectors u sed in neutrino experiments can be used to determine the muon momentum and thus their kinetic energy.\n\nĽuboš Krupa\n\nIEAP\, CTU in Prague\, Hus ova 240/5\, Prague\, Czech Republic\, Czech Republic LOCATION:IEAP\, CTU in Prague\, Husova 240/5\, Prague\, Czech Republic\, Cz ech Republic ORGANIZER:andre.sopczak@cern.ch SEQUENCE:4 SUMMARY:Cuspoid Vavilov-Cherenkov Radiation and Its Application in High-Ene rgy and Neutrino Physics URL;VALUE=URI:https://events.vtools.ieee.org/m/522187 X-ALT-DESC:Description: <br /><p>When studying the properties of the Vavilo v-Cherenkov radiation (VChR) arising from the arbitrary motion of a charge d particle in the transparent medium\, using the catastrophe theory\, the existence of a new type of radiation\, the cuspoid VChR\, was predicted.
