“…Another reason for the appearance of the orientation effect can be connected with the channeling and so-called flux peaking. The orientation effect of increasing the relative probability of a DD reaction in Pd due to channeling was investigated by computer simulations using the BCM-2.0 code [10]. The numerically obtained 20 keV D trajectories allow us to calculate the flux density of channeled D in dependence on the penetration depth and angle of incidence with respect to channeling planes.…”

“…The numerical solution of the equations of motion (2) was performed using a computer code BCM-2.0 [9,10]. Simulations of trajectories take into account angular divergence of the beam (for each entry point, several incident angles θ are generated) and allow calculating the flux density of the D beam inside the crystal.…”

At the ion accelerator HELIS at the LPI, the neutron yield is investigated from a deuteron-deuteron (DD) reaction in a deuterated Pd target, during an irradiation of its surface by a 20 keV deuterium (D) ion beam. The measurements of the neutron flux in the D beam direction are performed in dependence on the target angle β with respect to the D beam axis using a multichannel detector based on He 3 counters. A significant anisotropy in the neutron yield is observed, and it was higher by a factor of 2 at β ¼ 0 compared to that at β ¼ AE30°. The possible reasons for the anisotropy, including D ion channeling, are discussed. The orientation effect of increasing the relative probability of the DD reaction in Pd due to channeling was investigated by computer simulations using the BCM-2.0 code. The numerically obtained 20 keV D trajectories allow calculating the flux density of channeled D in dependence on the penetration depth and angle of incidence. The enhanced D flux density between crystal planes at a zero incident angle with respect to (200) Pd planes allows a qualitative explanation of the increase of the neutron yield in the DD reaction.

“…Both CB and B spectra have been drawn for the same radiator thickness. The use of the BCM-2.0 code [34] to calculate CR at axial channeling of 200 MeV 2020 JINST 15 C10011 electrons in W reveals a sharp peak of the radiation spectrum at about 6 MeV. The peaks for CR by 10 ÷ 50 MeV electrons are observed at the photon energies less than 1 MeV, the threshold for the e − e + pair production.…”

“…In our previous works [14 -17,29] we have developed a new method to figure the Bloch wave functions for planar and axial crystal orientations, the details of which is given in [30]. The present work aims in deducing the analytical expressions for spectral-angular CR distributions in thin crystals that demonstrate distinctive features of these dependences to be, in our opinion, of a special interest for future experimental studies.…”

On angular features of axial channeling radiation in crystals

Channeling of light relativistic particles in crystals is accompanied by intense radiation emission known as channeling radiation. Typically all calculations of channeling radiation aim in getting the total radiation intensity and its dependence on the parameters of particles and crystals. In the same time, since the discovery, the angular behaviours of channeling radiation have been studied just in a few works, in which only a polar dependence of the radiation intensity near the forward direction is estimated. However, simple analysis of the interaction potential predicts very specific features to be observed in the angular distributions of channeling radiation, especially at axial regime. In this work, for the first time, the expressions for angular and spectral distributions of electromagnetic radiation at axial channeling of relativistic charged particles in thin crystals are analytically refined within the QED theory. Obtained results allows predicting complex structures of radiation intensity and polarisation distributions. The results obtained might be of special interests for experimental studies.
