Super Conducting Magnets(SCM)

Info

Super conducting magnets are special magnets that harness the unique properties of superconductivity. Cooled using liquid helium or nitrogen to incredibly low temperatures, ~10K, the resistance in the magnets metal coils is nearly zero. This allows for larger magnetic fields to be generated with more efficient voltage generation. With the increased strength, they are used to bend higher rigidity beams like those found in FS2, BDS, and throughout the Fragment Seperator and Transfer Hall.

Tips/Notes

Operating most superconducting magnets requires special training given by SCM personnel. If you do not have this training do not operate SCMs unless authorized personnel are guiding you through the process.

Location

Superconducting magnets can be found in FRIB's, and ReA's beamlines as well as within the K500's beam chamber. The most common places for superconducting magnets are in each cryomodule in FRIB and ReA, both Artemis B and HPECR, and in the Target and Transfer Hall.

Devices/PV's

Superconducting solenoids, correctors, dipoles, quadrupoles, and other higher order magnets can all be found at FRIB.

SCM Shift Schedule

Shane:SCM does not only have dipoles, they also own the solenoids and the CIQT's in ARIS, (Cold-Iron Quadrupole Triplets), which are both focusing devices primarily

Shane: the coiled wires ARE the electromagnets, also could be clearer that the lower resistance allows for greater currents to pass through with lower voltages and less losses, current language is unclear

Shane: we have to start being careful here, I don't know where you sourced 10K, but it depends on the material. I don't know what they use, but the only figure I would be comfortable giving is <30K, as anything above that would be classified high temp and probably use nitrogen. We can't start putting unflagged speculation in here and might be good to site sources with these more technical pages

Shane: LS1 has SCM via solenoids, I think you're right that the FS2 Dipoles are the first SC Dipoles though

Shane: Phrasing of “With the increased strength, they are used to bend the beam after it leaves LS2 and moves through FS2 since the by the time beam leaves LS2 it has done most of its acceleration.” sounds awkward

Shane: Wish we had some numbers or theory here, that'd be a bigger change wiki-wide though

Shane: Not just found in LS2
