Big Science including accelerators

Oral

The HTS4 project, part of the CHART framework and the FCC Feasibility Study, investigates energy-efficient nested high-temperature superconducting (HTS) magnet systems for the FCC-ee short straight sections (SSS). Replacing selected normal-conducting magnets with nested ReBCO-based variants can reduce electricity consumption through two mechanisms: elimination of ohmic magnet losses and an...

HTS protection

Oral

One of the great advantages of High Temperature Superconductor (HTS) magnets is their high thermal stability. Yet many protection concepts envisioned for large magnets deliberately work against this property by improving normal-zone propagation through partial insulation, heaters, or other means. Better propagation may help distribute energy, but it also makes the coil itself less...

137. Implementation of new cooling methods and instrumentation development for HTS magnets in the CERN SM18 test facility

Novel Cryogenic and HTS Technologies

Oral

The SM18 superconducting magnet test facility has a long-standing history and large capacity for testing superconducting magnets for accelerators. Existing cooling capacity includes 1.9 K or 4.5 K helium bath cooling, as used in LHC and HL-LHC magnets, and helium gas cooling from 5 to 80 K, used for HTS magnet tests, mostly within the HFM program. For 2027, a new cryostat insert is in...
