The Francis Bitter national magnet laboratory at MIT: An update

Abstract The high DC field facility of the FBNML marked its 30th year of operation in its present location. This year's group of users once again included more than 300 experimenters involved in ≈ 100 programs. They exploited the advantages provided by the greatest number (32) and models (17) of high field DC magnets available anywhere in the world - and all at no charge. Bitter magnets with five different bore diameters provide a wide range of tradeoffs between bore size and maximum field. There are also both vertical and horizontal bore perpendicular access magnets. The operating characteristics of all these types will be presented.
