THE FRANCIS BITTER NATIONAL MAGNET LABORATORY AT MIT - AN UPDATE

The high DC field facility of the FBNML marked its 30th year of operat ion in its present location. This year's group of users once again inc luded more than 300 experimenters involved in approximately 100 progra ms. They exploited the advantages provided by the greatest number (32) and models (17) of high field DC magnets available anywhere in the wo rld - and all at no charge. Bitter magnets with five different bore di ameters provide a wide range of tradeoffs between bore size and maximu m field. There are also both vertical and horizontal bore perpendicula r access magnets. The operating characteristics of all these types wil l be presented.
