A Proposal for the IAXO Magnet System

The note describes a proposal for a superconducting toroidal magnet for the IAXO axion helioscope obtained assembling several canted solenoid dipoles. Respect to toroids made with racetrack coils, having the same average field, it has lower stored energy, lower peak magnetic field at the conductor and lower cold mass

Magnetic field, Lorentz forces and stored energy of multipole cos(nθ) and sector magnets with and without iron yoke

When approaching the design of a multipole magnet, such as a dipole, quadrupole, sextupole, and so on, it is highly advantageous to initiate the process by establishing the fundamental parameters. These parameters include conductor size, current density, inner and outer radius of the iron yoke, and more. This preliminary dimensioning enables the acquisition of the necessary specifications for the design. Within this report, analytical expressions for the magnetic field, Lorentz forces, and stored energy of multipole magnets with the cos(nθ) and sector coil configurations, both with and without the presence of an iron yoke, are derived. These derivations are based on the vector potential of a current line

Thermal analysis of the antineutrino 144Ce source calorimeter for the SOX experiment

The technical note describes the calorimeter which will be used to measure the activity of the antineutrino 144Ce source of the SOX experiment at the Gran Sasso Laboratories. The principle of the calorimeter is based on the measurement of both mass flow and temperature increase of the water circulating in the heat exchanger surrounding the source. The calorimeter is vacuum insulated in order to minimize the heat losses. The preliminary design and thermal Finite Element Analysis (FEA) are reported in the note

The Physical Connection and Magnetic Coupling of the MICE Cooling Channel Magnets and the Magnet Forces for Various MICE OperatingModes

A key issue in the construction of the MICE cooling channel is the magnetic forces between various elements in the cooling channel and the detector magnets. This report describes how the MICE cooling channel magnets are hooked to together so that the longitudinal magnetic forces within the cooling channel can be effectively connected to the base of the experiment. This report presents a magnetic force and stress analysis for the MICE cooling channel magnets, even when longitudinal magnetic forces as large as 700 kN (70 tons) are applied to the vacuum vessel of various magnets within the MICE channel. This report also shows that the detector magnets can be effectively separated from the central MICE cooling channel magnets without damage to either type of magnet component

Towards a muon collider

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. This Review summarises the status and the recent advances on muon colliders design, physics and detector studies. The aim is to provide a global perspective of the field and to outline directions for future work
