Sample Environment Systems for Temperature and Fields (TEFI)

The temperature and field (TEFI) platform provides sample environment and scientific support for experiments using magnetic and electrical fields, cryogenics and furnaces.

We will support the instrument teams with equipment and expertise,  in order to facilitate capable, reliable, fast turnaround experiments. Both wet and dry cryostat systems are envisaged; ESS will have an on-site helium liquefier enabling recovery and reliquefaction of helium gas.

We have a temperature/magnetic fields/pressure workshop where equipment can be tested and integrated.

We are working to establish further infrastructure and support for cryogenics equipment, furnaces, and equipment for high magnetic and electric fields.

A number of front-edge technologies are readily available on the market, and we will make use of these. They include wet and dry cryogenics, vacuum furnaces, superconducting magnets, and electromagnets.

Development Activities

We are developing systems for fast temperature change, automation, and in situ physical property measurements, and enabling control of multiple parameters.

In-Kind Partners

Roskilde University have developed a Peltier-based sub-cryostat insert for fast and accurate temperature change.

Collaborations

The ESS Accelerator Division and MAX IV are involved with the helium recovery system.
