Note: Optical filter method for high-resolution magnetostriction measurement using fiber Bragg grating under millisecond-pulsed high magnetic fields at cryogenic temperatures

High-resolution magnetostriction measurement of ΔL/L ∼ 10−6 at a speed of 5 MHz is performed using the optical filter method as the detection scheme for the fiber Bragg grating (FBG) based strain monitor under 35-ms pulsed high magnetic fields up to 45 T at 2.2 K. The resolution of magnetostriction...

Zusammenfassung:High-resolution magnetostriction measurement of ΔL/L ∼ 10−6 at a speed of 5 MHz is performed using the optical filter method as the detection scheme for the fiber Bragg grating (FBG) based strain monitor under 35-ms pulsed high magnetic fields up to 45 T at 2.2 K. The resolution of magnetostriction is about the same order as the conventionally reported value from FBG based magnetostriction measurement systems for millisecond pulsed magnetic fields. The measurement speed is ∼100 times the conventional ones. The present system can be a faster alternative for the conventional FBG based magnetostriction measurement system for millisecond pulsed high magnetic fields.
