4. Radiation challenges for magnets in present and future colliders (HL-LHC, FCC, Muon Collider)

Anton Lechner (CERN)

Oral contribution

Superconducting magnets in high-energy particle colliders are often exposed to a harsh radiation environment. In many cases, the magnets need to be sufficiently shielded in order to dissipate the radiation-induced heat and to protect equipment against long-term radiation damage. The secondary radiation fields and shielding requirements must be thoroughly studied during the design phase of...

36. J-PARC superconducting magnets and radiation environments

Dr Tatsushi Nakamoto (KEK)

15/01/2025, 14:55

Oral contribution

The J-PARC accelerator has been jointly operated by JAEA and KEK since 2007 and a variety of experiments has been carried out using secondary beams of pions, muons, neutrinos and other particles generated by proton beam with a power of several hundreds of kilowatts from 3 GeV Rapid Cycle Synchrotron and 30 GeV Main Ring. Superconducting (SC) magnets have been widely utilized in J-PARC. In...

10. The HiMB Project at PSI: Magnets in a high radiation environment

Alexandre Louis Gabard

15/01/2025, 15:20

Oral contribution

The Paul Scherrer Institute (PSI) operates the world’s most powerful continuous beam proton accelerator, capable of delivering a beam current of up to 2.4 mA with a beam power of 1.4 MW. The proton beam is directed at two carbon targets, generating a large flux of pions and muons. The interaction between the beam and the targets, along with beam scattering, results in a significant radiation...

16. Radiation environment in medical and industrial machines

Eric Forton, Vincent Nuttens

15/01/2025, 15:45

Oral contribution

Superconducting magnets have been used for more than fifteen years in protontherapy systems, starting with NbTi (Varian, IBA) and Nb3Sn (Mevion). These magnets, designed with large temperature, field and current margins, proved to be reliable and show no sign of conductor performance degradation.
The development of HTS presents opportunities and triggers questions about their suitability for...

5. Fusion magnets and their radiation environment

Daniele Torsello

15/01/2025, 16:40

Oral contribution

Among the key enabling technologies of compact fusion reactors there are high-temperature superconducting (HTS) magnets. Despite the great improvements recently achieved, one of the main challenges that still need to be faced is the evaluation of the impact of radiation in HTS tapes.

To face this challenge, it is crucial to have a comprehensive view of the radiation environment the HTS will...

26. The radiation environment within the STEP fusion device

Tim Eade

15/01/2025, 17:05

Oral contribution

The Spherical Tokamak for Energy Production (STEP) is the UK’s major technology and infrastructure programme to build a prototype fusion powerplant that will demonstrate net energy, fuel self-sufficiency and a viable route to plant maintenance.

STEP will use high temperature superconducting (HTS) magnet technology within toroidal and poloidal field (TF and PF) coils to confine the plasma....

14. Radiation Environment of ITER Superconductive Magnets

Davide Laghi (Fusion For Energy)

15/01/2025, 17:30

Oral contribution

During operation, ITER superconductive (SC) magnets are subjected to significant thermal loads which mostly result from the deposition of energy by plasma-generated neutrons, as well as from secondary gamma radiation produced when neutrons interact with matter. In addition to thermal loads, total neutron fluence and absorbed dose in key magnets components like the magnet’s insulators should be...
