Abstract

Recently proposed novel idea of "crabbed waist" beam-beam collisions will be tested at DAFNE during the collider run for the Siddharta experiment. In order to achieve the goal luminosity, large dynamic aperture is a matter of primary importance. A new method of a dynamic aperture optimization based on step-by-step chromaticity compensation with choosing the "best" sextupole pair at each step was applied to the DAFNE upgrade lattice. Several tune points were considered taking into account both high luminosity and large dynamic aperture. Algorithm and results of optimization will be presented.

High-Intense Gamma-Ray Emission from a Crystalline Undulator with Realistic Bending Profiles

The development of compact and intense $γ$-ray sources in the MeV energy range remains a significant frontier in radiation physics, with profound implications for nuclear physics, medicine and applied science. In this work, we present a comprehensive numerical investigation of the photon emission probability and brilliance of a Crystalline Undulator (CU) based on a periodically bent Si(110) crystal. Our approach integrates realistic deformation profiles obtained via Finite Element Method simulations of a realistic sample, where bending is induced by patterned Si$_3$N$_4$ surface stressors. Relativistic molecular dynamics simulations, performed using the MBN Explorer software package, consider a 10 GeV positron beam consistent with the foreseen FACET-II facility specifications. Our results reveal a distinct undulator radiation peak in the 1.6-2.1 MeV range, well-separated from the broader channeling radiation background. We show that for an optimal aperture angle of $1/2γ$, the source reaches a maximum peak brilliance of about $5\times10^{22}$~photons/s/mm$^2$/mrad$^2$/0.1\%~BW. This performance is highly competitive with large-scale Gamma-Beam Systems and exceeds that of Inverse-Compton Scattering sources, confirming the potential of crystalline undulators as high-brilliance, compact light sources for the MeV domain.

Simulation study of accelerator-based muography using the GeV-scale forward muon component at SHINE

Muography exploits the penetrating power of muons to image the interior of large dense objects, but cosmic-ray sources provide only ~1 {cm}^{-2} {min}^{-1} predominantly from above, limiting imaging speed and accessible geometries. Electron-driven muon production has recently been demonstrated with laser-wakefield accelerators, but shot-to-shot fluctuations hinder systematic studies required for quantitative accelerator muography. Using Geant4 Monte Carlo simulations, we model the full experimental setup at Shaft 2 of the Shanghai High repetition rate XFEL and Extreme light facility (SHINE), from a 3 GeV, 50 pC, 50 Hz commissioning electron beam interacting with a muon target through 25 m of beamline structures and a 3 m-thick concrete isolation wall. Approximately 0.28 effective reconstructed single-muon events per bunch, with residual kinetic energies below 1.2 GeV after traversing the wall, reach the downstream muography test area (~14 s^{-1}). The wall absorbs most charged background particles below ~1 GeV, while residual neutrons can be discriminated by their characteristic detector energy deposition. Scattering-tomography simulations show that $3\times 10^{5}$ effective muon events, accumulated in approximately 6 h at the commissioning rate, yield a Structural Similarity Index above 0.9, demonstrating the feasibility of quantitative accelerator-based muography using SHINE's electron-driven GeV-scale forward muon source. At the 8 GeV/50 kHz benchmark, the projected muon intensity exceeds $5 \times 10^{4}$ μ/s, corresponding conservatively to approximately one muon per bunch at the detector. This exceeds the cosmic-ray flux by orders of magnitude, while SHINE's superconducting linac provides a stable, controlled platform for developing electron-on-target muography.

Progress in Muon Cooling and Moderation Techniques

Muon beams are essential tools for a wide range of applications such as the search for rare muon decays and muon spectroscopy. However, conventional muon beams produced from pion decay have large emittance and broad momentum spread. Conventional beam-cooling techniques cannot improve the beam quality significantly owing to the 2.2 $μ$s muon mean lifetime. This has motivated the development of dedicated muon beam cooling and moderation methods. This review surveys the principal approaches, including ionisation cooling for high-brightness muon beams, low-energy muon moderation and frictional cooling for slow muon production, and laser ionisation of thermal muonium for ultra-low-emittance muon sources. The challenges associated with producing slow negative muons and emerging concepts based on cyclotron trapping and muon-catalysed fusion are also discussed. These complementary techniques offer promising pathways towards next-generation muon facilities and precision experiments.
