Our priinary responsihility is to supply new high Ciclrl cnpaciior drivcn coils wirh iiicr~xiscd capabilities for the NI-IMPI, Pulsed Field User Faciliiy at the Los Alninos National Laboratory (LANL). These standard user mils include o 5DT and 601' short pulsc magnet with 24 m m and 15 min bores respectively, cis well as a 40T long pulse magnet with U. 24 m m bore [l]. At this timc we are also collaborating with NIIMFL LANL on ihc dcsign niid constriiction of the insert ctd for the 1011T noli-destructive magnet Wig.
