The equipment of the Laboratory for Magnetic Measurements at BENSC consists of five cryomagnets and one virtual instrument, a finite elements program (Comsol Multiphysics). The cryomagnets are equipped with different measurement options and cover the temperature range from 10 mK up to 1000 K at magnetic fields up to 14.5 T. One of the instruments (CM-17T) is currently under construction and therefore has limited access for user experiments.

The user measurements can be performed in two modalities: "ordered measurements" and "own measurements". An ordered measurement will be performed by a member of the LaMMB - MagLab staff, the presence of the proposer of the measurement is not necessary. For some of the measurement options this is the only possible choice because of the complexity of the experiments. For example this is the case for all measuremets at CM-8T or CM-14.5T. Other experiments can and should be performed by the proposers themselves ("own measurement"). For unexperienced users, the LaMMB - MagLab instrument responsibles will give a detailed introduction on the instruments and will provide assistance during the measurements.
