Pulsed field instrumentation

The LNCMI conducts extensive developments of instrumentation compliant with the particular constraints of pulsed field magnets. The technical challenges comprise very low (100 mK) temperatures, limited sample space, mechanical and electrical noise, vacuum, high pressure, in-situ sample rotation.

As pulsed field magnets are very different from any magnet, the LNCMI designs, constructs, operates and refines tailored cryogenic devices like 4He and 3He cryostats or 3He/4He dilution refrigerators to acomodate the constrains of pulsed fields magnets.

The LNCMI provides technical support to external visitors using the high magnetic field facilities:

An in-house researcher or engineer (the “local contact”), who is specialized in the scientific domain and the experimental technique, is attributed to each user experiment. The local contact is the primary contact person for all scientific and technical issues during the preparation and the experiment’s execution.

In addition, the engineers and technicians of the LNCMI’s scientific instrumentation teams provide technical support to users and their local contacts. They are particularly responsible for  general instrumentation in the high magnetic field environment, as well as the user equipments for sample preparation.

Moreover, the LNCMI continuously develops and improves experimental techniques like contactless resistance measurements (TDO), optical spectroscopy, single sweep NMR, and many others. Theses developments of new techniques and devices are realized in close collaboration between the researchers and the cryogenics, scientific instrumentation teams and the mechanical workshop.
