Stability of Three- and Four-Body Coulomb Systems
/ Martin, Andre (CERN ; Annecy, LAPP)
We discuss the stability of three- and four-particle system interacting by pure Coulomb interactions, as a function of the masses and charges of the particles. We present a certain number of general properties which allow to answer a certain number of questions without or with less numerical calculations..

Advances in magnet and shielding designs for fusion and high energy physics applications
/ Giannini, L (Unlisted, DE) ; Luongo, C (Unlisted, DE) ; Bottura, L (CERN) ; Bordini, B (CERN) ; Lechner, A (CERN) ; Kolehmainen, A (CERN) ; Leichtle, D (KIT, Karlsruhe, TTP) ; Portone, A (Virginia Tech.) ; Testoni, P (Virginia Tech.) ; Bajari, J (Unlisted, DE) et al.
This paper introduces the work scope of a collaboration among EUROfusion, CERN, and F4E to create models and design tools applicable both for fusion devices and muon accelerator magnets. The study described here is motivated by the commonality in challenges to design magnets and radiation shields applicable to compact fusion machines to serve as neutron source, and future high-energy physics experiments such as the muon collider or high intensity neutrino factories.

Isovector axial and pseudoscalar form factors from twisted mass lattice QCD at the physical point
/ Alexandrou, Constantia (Cyprus U. ; Cyprus Inst.) ; Bacchio, Simone (Cyprus Inst.) ; Constantinou, Martha (Temple U.) ; Finkenrath, Jacob (CERN) ; Frezzotti, Roberto (INFN, Rome) ; Kostrzewa, Bartosz (Bonn U., ITKP) ; Koutsou, Giannis (Cyprus Inst.) ; Spanoudes, Gregoris (Cyprus U.) ; Urbach, Carsten (Bonn U., ITKP)
We present the isovector axial, induced pseudoscalar, and pseudoscalar form factors of the nucleon using three twisted-mass fermion ensembles with degenerate up- and down-, strange-, and charm-quarks with masses tuned to their physical values (physical point). The three ensembles have lattice spacing a=0.08, 0.068, and 0.057 fm and approximately equal physical volume allowing for the continuum limit to be taken at the physical point. [...]

This article presents a method for researching processes in automatic control systems based on the operator approach for modelling the control object and the controller. Within the method framework, a system of equations has been developed that describes the relations between the control error, the reference and control action, the output coordinate and the controller and the control object operators.

Multi-Reflection Time-of-Flight (MR-ToF) devices are powerful tools for high-precision mass spectrometry, highly selective and high-flux mass separation as well as, most recently, for highly sensitive laser spectroscopic applications. In this work, various ion-optical simulations are conducted to provide insights into optimizing the design of the MR-ToF apparatus to enhance performance across its diverse application fields. [...]
