Development of Radiation-Tolerant HTS Magnet for Muon Production Solenoid

Abstract

Superconducting magnets are widely used in accelerator science applications. Muon production solenoids are applications that have recently attracted considerable public attention, after the approval of muon-related physics projects such as coherent muon to electron transition or muon-to-electron-conversion experiments. Based on its characteristics, muon production solenoids tend to be subjected to high radiation exposure, which results in a high heat load being applied to the solenoid magnet, thus limiting the superconducting magnet operation, especially for low-temperature superconductors such as niobium titanium alloy. However, the use of high-temperature superconductors may extend the operation capabilities owing to their functionality at higher temperatures. This study reviews the characteristics of high temperature superconductor magnets in high-radiation environments and their potential for application to muon production solenoids.

REBCO -- a silver bullet for our next high-field magnet and collider budget?

“…The implication is that rebco magnets can provide sufficient magnetic fields to bend and focus particles for future hadron and muon colliders looking for magnets in the 16 -20 T range. The high stability margin and the capability to operate at a temperature above 4.2 K can be particularly suitable in applications with high thermal deposition to the magnet systems and fast-ramping magnets [17] that can be tricky for low-temperature superconducting magnets [18,19] .…”
