The Grenoble High Magnetic Field Laboratory (GHMFL), in collaboration with
the Oxford Instrument Company and the University of Stuttgart, is developin
g a project named Giga-NMR. The goal of this project is to achieve a field
of 21 T in a cold bore diameter exceeding 100 mm with a sufficient spatial
homogeneity and temporal stability to allow for NMR investigations. The con
cept and principles to achieve this goal are described together with a prel
iminary schedule.
