Performing experiments at the Grenoble high magnetic field laboratory: Application to the study of the J_c(B) dependence of Bi-2223/Ag multi-filamentary superconducting tapes

The Grenoble High Magnetic Field Laboratory was built to meet the requirements of scientists for experiments implying the use of very high magnetic fields. Currently, the facility operates for over 5000 h a year and thanks to its most powerful magnets, it allows the production of steady magnetic fields up to 30 T. Scientists have access to the high magnetic field facility provided they have submitted a proposal for experiments in high magnetic fields and have obtained the Program Committee's approval to carry out their research project. As illustration of the use of our specific instrumentation, we present a study of the behavior of the critical currents of superconducting tapes, performed in collaboration between CNRS Grenoble, France and NIN Xi'an, China.
