Overview of the Quench Heater Performance for MQXF, the Nb$_{3}$Sn Low-$\beta$ Quadrupole for the High Luminosity LHC
In the framework of the High-Luminosity upgrade of the Large Hadron Collider, the US LARP collaboration and CERN are jointly developing a 150 mm aperture Nb$_{3}$Sn quadrupole for the LHC interaction regions. Due to the large stored energy density and the low copper stabilizer section, the quench pr...

| description | In the framework of the High-Luminosity upgrade of the Large Hadron Collider, the US LARP collaboration and CERN are jointly developing a 150 mm aperture Nb$_{3}$Sn quadrupole for the LHC interaction regions. Due to the large stored energy density and the low copper stabilizer section, the quench protection of these magnets is particularly challenging, relying on a combination of quench heaters attached to the coil surface and CLIQ units electrically connected to the coils. This paper summarizes the performance of the quench heater strips in different configurations relevant to machine operation. The analysis is focused on the inner layer quench heaters, where several heater strips failed during powering tests. Failure modes are discussed in order to address the technology issues and provide guidance for future tests. |
