EPJ D Topical review - Crystal-based intensive gamma-ray light sources

In a Topical review just published in EPJD, A.V. Korol and A.V. Solov'yov (MBN Research Center, Germany) discuss possibilities for designing and practical realization of novel intensive gamma-ray Crystal-based LSs (CLS) operating at photon energies from 102 keV and above that can be constructed exposing oriented crystals to beams of ultrarelativistic particles. CLSs can generate radiation in the photon energy range where the technologies based on the fields of permanent magnets become inefficient or incapable.

In an exemplary case study the authors consider a CLS based on a periodically bent crystal. It is demonstrated that peak brilliance of radiation in the photon energy range 1-102 MeV by currently available positron beams is comparable to or even higher than that achievable in conventional synchrotrons at much lower energies. By propagating pre-bunched beams the brilliance can be boosted by orders of magnitude reaching the values accessible in the state-of-the-art magnetic undulators and matching the values achievable at the XFEL facilities which operate in much lower photon energy range.

The size and the cost of CLSs are orders of magnitude less than that of modern LSs based on the permanent magnets. This opens many practical possibilities for the efficient generation of gamma-rays with various intensities and energies by means of the existing and to-be constructed beam-lines.

When developed, CLSs will have many applications in basic sciences, technology and medicine. They could be used for disposing of nuclear waste, nuclear medicine, production of rare isotopes, photo-induced nuclear reactions, medical applications, non-destructive imaging of complex molecular systems with the resolution allowing detection of positions of the nuclei, and gamma-ray material diagnostics.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
