Abstract

The manufacturing and commissioning of superconducting magnet coils was monitored using embedded optical fibre Bragg grating sensors (FBG) fabricated in highly linearly birefringent (HiBi) fibre. Strain developed in the coils was monitored from the resin impregnation and curing process, through cool down of the magnet in a helium cryostat from room temperature to 4 K, to energising the coils. The development of multiple components of strain in the coils when the magnet quenched was monitored, revealing phenomena that it had not been previously possible to measure using other sensor technologies.
