Abstract

It is well known that the alignment of an high-energy electron beam with specific crystal directions leads to a significant increase of the coherent radiation emission. This enhancement can be exploited to create an intense photon source. An elective application is an innovative positron source design for future lepton colliders. Such scheme takes advantage of lattice coherent effects by employing a high-Z crystalline radiator, followed by an amorphous metallic converter, to generate positrons via a two-step electromagnetic process. Additional applications can be in neutron production through photo-transmutation and radionuclide generation via photo-nuclear reactions. In this work, we present experimental results obtained from beam tests at CERN’s PS facility using commercial industrial-grade tungsten crystals. The obtained results demonstrate the robust performance of industrial-grade radiators, even with their inherent imperfections, suggesting that it is possible to simplify the supply process and it is not strictly necessary to rely on highly specialized research infrastructures.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
