Abstract

Beam halo monitoring is crucial for high-intensity machines such as the HL-LHC. Carbon Nanotube (CNT) wires offer a promising alternative to conventional carbon fibre scanners due to their lower density, improved thermal properties, and reduced beam interaction. This work evaluates their thermal performance and survivability through simulations at SPS and HL-LHC beam conditions. Results indicate that CNT wires can tolerate HL-LHC beam-induced heating in dynamic scanning mode for halo measurements in the 3.5-6.5 σ range, remaining below the 1600 K sublimation threshold. In contrast, stationary operation closer to the core produces sustained heating and higher thermal risk. While challenges remain in manufacturing, post-processing, and property variability, CNT wires show strong potential for non-destructive halo diagnostics, provided long-term performance can be optimised.
