Miniature solenoid for the production of confined magnetic flux

For experiments involving SQUID’s it is sometimes desirable to have a small source of confined magnetic field in order to provide a dc or rf flux bias. This has been done by closely winding ♯50 AWG copper wire on a 250‐μm‐diam optical fiber. The resulting solenoid is very small and has excellent mec...

Description
Summary:For experiments involving SQUID’s it is sometimes desirable to have a small source of confined magnetic field in order to provide a dc or rf flux bias. This has been done by closely winding ♯50 AWG copper wire on a 250‐μm‐diam optical fiber. The resulting solenoid is very small and has excellent mechanical and electrical properties at 4 K.
