Short summary
The High-Luminosity Large Hadron Collider (HL-LHC) project at CERN will require new superconducting magnets with strict requirements in terms of field quality. A new measurement system based on rotating coils has been developed to characterize them with high accuracy. The system measures the required quantities in a single run, which greatly reduces the necessary time and resources. Thanks to its versatility, it can be adapted to a variety of magnet sizes without major effort.
