Coherent bremsstrahlung, coherent pair production, birefringence and polarimetry in the 20-170 GeV energy range using aligned crystals
NA59 Collaboration, A. Apyan, R. O. Avakian +27
The processes of coherent bremsstrahlung (CB) and coherent pair production (CPP) based on aligned crystal targets have been studied in the energy range 20-170 GeV. The experimental…
Results on the Coherent Interaction of High Energy Electrons and Photons in Oriented Single Crystals
NA59 Collaboration, A. Apyan, R. O. Avakian +27
The CERN-NA-59 experiment examined a wide range of electromagnetic processes for multi-GeV electrons and photons interacting with oriented single crystals. The various types of cry…
Measurement of Coherent Emission and Linear Polarization of Photons by Electrons in the Strong Fields of Aligned Crystals
NA59 Collaboration, A. Apyan, R. O. Avakian +27
We present new results regarding the features of high energy photon emission by an electron beam of 178 GeV penetrating a 1.5 cm thick single Si crystal aligned at the Strings-Of-S…
Linear to Circular Polarisation Conversion using Birefringent Properties of Aligned Crystals for Multi-GeV Photons
NA59 Collaboration, A. Apyan, R. O. Avakian +27
We present the first experimental results on the use of a thick aligned Si crystal acting as a quarter wave plate to induce a degree of circular polarisation in a high energy linea…
Coherent Pair Production by Photons in the 20-170 GeV Energy Range Incident on Crystals and Birefringence
NA59 Collaboration, A. Apyan, R. O. Avakian +27
The cross section for coherent pair production by linearly polarised photons in the 20-170 GeV energy range was measured for photon aligned incidence on ultra-high quality diamond…
Experimental investigation of high-energy photon splitting in atomic fields
Sh. Zh. Akhmadaliev, G. Ya. Kezerashvili, S. G. Klimenko +17
The new data analysis of the experiment, where the photon splitting in the atomic fields has been observed for the first time, is presented. This experiment was performed at the ta…
