On Volume Reflection of Ultrarelativistic Particles in Single Crystals
نویسنده
چکیده
The analytical description of the volume reflection of the charged ultrarelativistic particles in bent single crystals is considered. The relation describing the angle of volume reflection as a function of the transversal energy is obtained. The different angle distributions of the scattered protons in the single crystals are found. Results of calculations for 400 GeV protons scattered by the silicon single crystal are presented.

Volume Capture and Volume Reflection of Ultrarelativistic Particles in Bent Single Crystals
Influence of volume capture on a process of volume reflection of ultrarelativistic particles moving in bent single crystals was considered analytically. Relations describing various distributions of particles involving in the process, the probability of volume capture and behavior of channeling and dechanneling fractions of a beam were obtained. Results of study will be useful at creation of mu...
متن کاملRadiation of Photons in Process of Charge Particle Volume Reflection in Bent Single Crystal
New type of radiation in crystals is predicted and investigated in computer simulation. It is shown that process of volume reflection of electrons and positrons in bent crystals is accomplished with high-power radiation of photons. Volume reflection radiation has intensity comparable with known channeling radiation, but it is less sensitive to entrance angle and sign of charge of a particle. Si...

Background: Similar to the thermoluminescence (TL) spectra, the optical parameters variations can also be used in TL crystals for dosimetry purposes. These optical parameters can include absorption, transmission and reflection coefficients. Materials and Methods: Single crystals of KBr and KCl which have been used in this research were grown from laboratory grade extra pure precursor p...
متن کاملA Possibility of Volume Refraction of Negative Relativistic Particles in Bent Crystals
The volume coherent deflection of high-energy positive and negative particles in uniformly bent crystals is studied. The general analysis of potential scattering shows that the standard screening potential for a large class of collisions can cause the volume refraction for negative particles (antiprotons, electrons) instead of the volume reflection for positive particles (proton, positrons). PA...

Single crystals of Cd.96Zn.04Te (CZT) with 14 mm in diameter were grown by seedless modified Bridgman method. Also, crystals with the same chemical composition were grown by vapor phase inert gas-transport method (VPGT), and single crystals up to 3.5 mm in diameter were obtained. Structural studies by XRD and back reflection Laue method show that the grown crystals are single phase with high pu...
