Summary
This paper presents experimental results on damage mechanisms in superconducting accelerator magnet components exposed to instantaneous beam impact, a critical concern for the LHC and other high-energy physics facilities. The work combines three complementary experimental methods—thermal degradation studies, rapid temperature rise simulations, and direct 440 GeV proton beam exposure—to characterise how energy deposition affects insulation integrity and superconducting performance in Nb-Ti and Nb₃Sn materials. Findings support improved predictive models for machine protection systems as beam brightness increases.
UK applicability
This research is specific to particle accelerator engineering and has no direct application to UK farming systems, soil health, or food production. It is outside the scope of Vitagri's Pulse Brain catalogue.
Key measures
Insulation breakdown voltage, critical current of superconducting strands, degradation of insulation strength following high-temperature exposure and proton beam impact
Outcomes reported
The study assessed degradation mechanisms in Nb-Ti and Nb₃Sn superconducting strands and cable stack insulation through three experimental approaches: room-temperature magnetization and breakdown voltage measurements, fast capacitor discharge to simulate millisecond temperature rises, and direct exposure to 440 GeV proton beam.
