CNRS

As the largest fundamental research organization in Europe, the CNRS carries out research in all fields of knowledge, through its ten institutes. The organization's annual budget represents a quarter of French public spending on civilian research. The CNRS aims to:

  • Evaluate and carry out all research capable of advancing knowledge and bringing social, cultural, and economic benefits for society.
  • Contribute to the promotion and application of research results.
  • Develop scientific information.
  • Support research training.
  • Participate in the analysis of the national and international scientific climate and its potential for evolution in order to develop a national policy.

Labs involved in the project:

The LNCMI, one of the large research infrastructure of the CNRS is the National High Magnetic Field facility of France. It is a founding member of the European Magnetic Field Laboratory (EMFL).

The 24 MW power supply of the Grenoble site, dedicated to the generation of static fields generates up to 36 T in a 34 mm room temperature diameter bore. A project is ongoing to reach 43 T by mean of a hybrid magnet combining a 8.5 T NbTi 800 mm room temperature diameter bore solenoid with a resistive magnet producing 34.5 T.

One of the crucial current question for high field facilities round the world is to evaluate the reliability of High Temperature Superconducting coils to provide part of the fields of their high field magnets.  

Role: 

The LNCMI will be implied in the T5.4: Technology demonstrator of an HTS insert for High Field Magnet Laboratories (HFML). 

Relevant Projects: 

ANR NOUGAT

(french founding 2014/2018) Leader, X. Chaud (LNCMI) development of a 10 T HTS insert in a 20 T background resistive magnetic field

LASUP

french EQUIPEX (2011-2018) Leader P. Pugnat, co-leaders, B. Hervieux (CEA),  L. Ronayette (LNCMI), F. Debray (LNCMI) for the construction of a 43 T NbTi/resistive hybrid magnet

Additional Information
Infrastructure

The high field facility in Grenoble is a unique place where high magnetic fields are available in large bore. It is then possible to test HTS in very severe magnetic environments. Today 20 T is available in 170 mm and 10 T in 376 mm with the corresponding cryostats at variable temperature. From 2019, as a result of the ongoing hybrid project, these values will be upgraded to 27 T in 170 mm and 17 T in 376 mm.
