Several magnets that are part of the user program — SCM1 and SCM2, Cells 9, 12 and 15 — have cryogenic systems installed with probes that conveniently allow for “plug and play” measurements using 8- and 16-pin connectors. Many users choose to mount samples on these platforms at their home institutions so they are prepared when they arrive at the MagLab. The direction of the applied field of the magnets can be reversed for Hall effect measurements and rotation probes are available for determining the angular dependence of the magnetoresistance.
