Carbon nanotube wires for accelerator applications

This review explores the transformative potential of carbon nanotubes (CNTs) and their assemblies as next-generation materials for high-intensity beam diagnostics in particle accelerators. Thanks to their thermal conductivity, mechanical strength, and radiation resistance, CNTs offer substantial advantages over traditional materials used in high energy accelerator environments. The paper examines recent advances in CNT synthesis, purification, and fabrication techniques, assessing their performance under the extreme conditions imposed by high-intensity beams. It highlights experimental findings on CNT wire durability and thermal management, underscoring their promise not only for beam instrumentation but for a broad range of applications in these extreme environments. These developments open new options for tackling current challenges and directing future research for successful implementation. • Made of aligned nanotubes, these wires are light, strong, and conduct electricity. • Carbon nanotube wires outperform carbon in heat, strength, and radiation traits. • Cleaning removes residue and carbon, improving lifespan and conductivity. • They handle radiation well; low doses help, high doses still cause damage. • Useful for sensors, beam sources, radio parts, shielding, or tiny accelerators.
