Members of the TECHNO-CLS consortium from INFN, the University of Padova, the University of Ferrara, and the University of Kent visited the Diamond Light Source in the UK to analyse the new prototypes of crystalline undulators formed by periodically undulated silicon and germanium crystals. Based on the innovative use of lithography techniques, sputtering, and laser techniques, this new generation of undulators are now in an important testing phase at B16 beamline.

Conceptual paper: G. B. Sushko, A. V. Korol, and A. V. Solov’yov, Intense gamma-ray light sources based on oriented single crystals, Phys. Rev. Accel. Beams 27 (2024) 100703.
In this paper, the feasibility of gamma-ray light sources based on the channeling phenomenon of ultrarelativistic electrons and positrons in oriented single crystals is demonstrated using rigorous numerical modelling. Case studies are presented for 10 GeV and sub-GeV electron and positron beams incident on thick (up to few millimeters) diamond and silicon crystals. It is shown that for moderate values of the beam current (≤10 microamperes), the average photon flux in the 1-200 MeV energy range emitted within the narrow cone and bandwidth can be in the order of 1010 photons/s for electrons and 1012 photons/s for positrons. These values are higher than the fluxes available at present.

Talk "Silicon Crystalline Undulator Based On Silicon Nitride Stressor Layer Patterning: Design and Building from TECHNO-CLS Project" at the 10th Intnl. Conf. "Charged & Neutral Particles Channeling Phenomena", Riccione, Italy. Lorenzo Malagutti (on behalf of the INFN, UNIFE, UNIPD and MBN-RC teams)
Abstract: Current limitations in the field of undulators include the inability of state-of-the-art magnetic undulators to achieve periods shorter than a few centimeters. To overcome these limitations, Crystalline Undulators (CUs) consist of periodically bent crystals in which channeled electrons or positrons follow the bending of the crystalline planes must be developed. These CUs aim to generate intense and monochromatic sources of hard X and γ electromagnetic radiation with energies from 100 keV to GeV. In this work, we present a novel approach exploiting silicon nitride stressor layer to produce short period CUs. We report the results of finite element method (FEM) analysis of CUs and the evaluation of the optimal geometric parameters for the undulator, revealing detailed 3D deformation and the related emitted radiation spectrum. Additionally, dynamic simulations were conducted using the relativistic atomistic molecular dynamics approach implemented in MBN Explorer. We fabricated first prototypes of CUs using advanced silicon microelectronics techniques, facing significant challenges from an experimental manufacturing perspective.
