“…In colliders, it is the case for interaction regions where large solenoidal fields and compensation elements are present. Atypical optics schemes based on strong coupling insertions have also been proposed to improve the performance of lepton and hadron colliders, such as the "Möbius accelerator" [3], planar-to-circular beam adapters for circular modes operation [4], and round beam operation for lepton storage rings [5,6].…”

The coupling of transverse motion is a natural occurrence in particle accelerators, either in the form of a residual coupling arising from imperfections or originating by design from strong systematic coupling fields. While the first can be treated perturbatively, the latter requires a robust approach adapted to strongly coupled optics, and a parametrization of the linear optics must be performed to explore beam dynamics in such peculiar lattices. This work highlights the key physical interpretations of the main parametrization formalisms to describe linear coupled optics, along with explicit links and comparisons of these parametrizations. Concepts rarely illustrated in other works, such as forced mode flips and local coupling, are explored in detail, clarifying some anomalies that can arise in lattice functions. The analytical methods have been implemented in a reference Python package and connected with ray-tracing and integration codes to explore examples of strongly coupled lattices, which are discussed in detail to highlight the key physical interpretations of the parametrizations and characteristics of the lattices.

“…The CMD-3, Cryogenic Magnetic Detector, is a general-purpose detector for experiments at the VEPP-2000 e + e − collider in the Budker Institute of Nuclear Physics (BINP) in Novosibirsk. The VEPP-2000 [1,2] is the only collider which operates now in the center-of-mass (c.m.) energy range from 320 MeV up to 2 GeV.…”

“…energy of 2 GeV that exceeds the luminosity of the colliders operated earlier in this energy range by at least one order of magnitude (excluding DAΦNE which operates in the narrow energy range around the φ-meson). High luminosity in the single-bunch mode is achieved using the novel round beam technique [1,2] developed at BINP. The beam energy is monitored with a precision of ∆E/E = 6 • 10 −5 using the Compton backscattering method [3].…”

View full text Add to dashboard Cite

+ e − collider has been operated in the Budker Institute of Nuclear Physics since 2010. Experiments are carried out with two detectors CMD-3 and SND. The calorimetry at the CMD-3 detector is based on three subsystems, two coaxial barrel calorimeters -Liquid Xenon calorimeter and crystal CsI calorimeter, and end cap calorimeter with BGO crystals. This paper describes the procedures of the energy calibration of the combined barrel calorimeter of the CMD-3 detector.
