Since 2013, the LNCMI is collaborating with the Toulouse company Bmax / I Cube Research to design magnetoforming coils with long lifetime. Durability is a crucial issue for using electromagnets at an industrial scale, requiring the production of parts in large quantities with extreme precision and at controlled cost. To [...]
Rolf Pfister, Michael Kamke, Eric Verney, Mickaël Pelloux, Eyub Yildiz, Luc Ronayette, and Pierre Pugnat, LNCMI Grenoble. The hybrid magnet, combining resistive and superconducting technologies and that is under construction at LNCMI-Grenoble, has reached important milestones in 2021 despite the Covid-19 sanitary crisis. After a thorough preparation phase, we successfully [...]
Jérôme Béard, LNCMI Toulouse. We have designed a novel pulsed magnetic dipole, called foil coil, which can deliver a transverse magnetic field of more than 10 T along a 0.85 m optical access operating without cryogenic equipment. This magnet is dedicated to linear magnetic birefringence measurements in the framework of [...]
The primary objective of the EU funded design study SuperEMFL is to add an entirely new dimension to the EMFL through the development of all-superconducting user magnets at unprecedented field strengths of 40 T and beyond, granting the European high-field user community access to such high superconducting magnetic fields, more [...]
Pierre Pugnat, Rolf Pfister, and Luc Ronayette, LNCMI-Grenoble. The hybrid magnet in construction at LNCMI-Grenoble is based onthe combination of resistive inserts, made of Bitter and polyhelix coils, with a large-bore superconducting outsert. It will produce in a first step, an overall continuous magnetic field of 43 T in a [...]

Matsuda, IMGSL-ISSP Kashiwa, University of Tokyo. 40 years ago, Prof. Chikazumi launched a project to realize extremely high magnetic fields by using electromagnetic flux compression (EMFC) at ISSP, and the project was taken over by Profs. Miura and Takayama. In 2018, a magnetic [...]
Toshihiro Nomura* and Sergei Zherlitsyn, HLD Dresden. A quartz-crystal microbalance (QCM) is an ultrasensitive device to detect changes of the mass. When an external mass is coupled to the surface of the quartz micromembrane, the resonance frequency f0 of the QCM decreases. Owing to the high quality factor, Q, [...]
Jung-bin Song, X. Chaud, F. Debray, LNCMI-Grenoble and P. Fazilleau, T. Lécrevisse, CEA Saclay. The High Temperature Superconductor (HTS) team at LNCMI has set a new world record by producing a magnetic field of 32.5 T for a period of several minutes. With this, EMFL is paving the way [...]
Xavier Chaud, LNCMI Grenoble. The development of high-temperature superconductor (HTS) inserts for all superconducting magnets for fields above 23 T is highly desirable. With practically zero power consumption this will make possible long-duration experiments at a low operation cost and will be greatly beneficial for physics, chemistry, and live [...]
In the beginning of March 2018, a major milestone in the development of the 45 T hybrid magnet at HFML in Nijmegen has been achieved with the completion of the superconducting coil for the outsert magnet. The building process of the coil, with an outer diameter of 1.2 meter, [...]
