“…The SIDDHARTA experiment [9] employed in 2009, for the first time, a SDDs based system to perform the kaonic hydrogen (K -H) x-ray spectroscopy at the DAΦNE collider [10,11] of Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali di Frascati (INFN-LNF), achieving the most precise measurement of the shift (ε) and the width (Γ) for the K-H fundamental level. Combining this result with the analogous measurement of the kaonic deuterium (Kd) 2p→1 s transition, to be performed by SIDDHARTA-2 in 2021, it will be possible to extract the isospin dependent antikaon-nucleon scattering lengths, which are fundamental quantities for understanding the low-energy QCD in the strangeness sector.…”

Single-particle dynamics in a nonlinear accelerator lattice: attaining a large tune spread with octupoles in IOTA

Fermilab is constructing the Integrable Optics Test Accelerator (IOTA) as the centerpiece of the Accelerator R&D Program towards high-intensity circular machines. One of the factors limiting the beam intensity in present circular accelerators is collective instabilities, which can be suppressed by a spread of betatron frequencies (tunes) through the Landau damping mechanism or by an external damper, if the instability is slow enough. The spread is usually created by octupole magnets, which introduce the tune dependence on the amplitude and, in some cases, by a chromatic spread (tune dependence on particle's momentum). The introduction of octupoles usually has both beneficial (improved Landau damping) and harmful properties, such as a resonant behavior and a reduction of the dynamic aperture. One of the research goals at the IOTA ring is to achieve a large betatron tune spread, while retaining a large dynamic aperture, using conventional octupole magnets in a special but realistic accelerator configuration. The configuration, although not integrable by design, approximates an autonomous 2D Hamiltonian system. In this paper, we present results of computer simulations of an electron beam in the IOTA by particle tracking and the Frequency Map Analysis. The results show that the ring's octupole magnets can be configured to provide a betatron tune shift of 0.08 (for particles at large amplitudes) with the dynamical aperture of over 20 beam sigma for a 150-MeV electron beam. The influence of the synchrotron motion, lattice errors, and magnet imperfections is insignificant for the parameters and levels of tolerances set by the design of the ring. The described octupole insert could be beneficial for enhancing Landau damping in high intensity machines.

“…only at IP2. A new Crab-Waist (CW) collision scheme [7][8][9] was implemented for the first time ever. Thanks to this, a peak luminosity L = 4.5 × 10 32 cm −2 s −1 was reached, two orders of magnitude higher than the one measured by other colliders working at the same c.m.…”

The Frascati National Laboratory (LNF) is the largest and the oldest among the National Laboratories of the Italian Institute for Nuclear Physics (INFN). Since its foundation in 1954, it has been devoted to two main activities: the development, construction and operation of particle accelerators; the design and construction of forefront detectors for particle, nuclear and astroparticle physics. The research program of LNF is focused on fundamental research, but interdisciplinary activity has grown of importance along the years, with a perfect balance between internal and external activities. The scientific program taking place at LNF, at present, is still centered on the DAΦNE complex, but in the last years, a second accelerator infrastructure, SPARC\_LAB, devoted to the study and development of new technique of particle acceleration is marking the path toward the future: EuPARXIA. This will be an European infrastructure for plasma acceleration development. In this paper, an overview of the research program of the Laboratory and of the future perspectives is presented.
