THE FIRST WALL STRUCTURES FOR FUTURE FUSION REACTORS ARE LIKELY TO CONSIST OF GRAPHITE OR CARBON/CARBON COMPOSITE BRAZED TO AN ACTIVELY COOLED METAL SUBSTRATE. THIS PROJECT INVOLVES A TECHNIQUE FOR VACUUM INFILTRATING ONE SIDE OF THEGRAPHITE WITH MOLTEN COPPER. SUCH INFILTRATED MATERIALS SHOULD BE MORE EASILY BRAZED THAN GRAPHITE OR CARBON/CARBON COMPOSITES. THE RESULTING JOINTS ALSO SHOULD HAVE I ...

VERTICAL SEISMIC PROFILES (VSPS) PROVIDE INFORMATION FOR MORE PRECISELY INTERPRETING INTO GEOPHYSICAL SEISMIC DATA, AS WELL AS GEOPHYSICAL INFORMATION BEYOND THE LIMITS OF THE WELLBORE. THE HIGH DEGREE OF REDUNDANCY NECESSARY TO ACQUIRE THIS TYPE OF DATA, AND THE COMPLICATIONS THAT CAN ARISE FROM PLACING GEOPHONES DOWN A BOREHOLE MAKE DATA ACQUISITION EXPENSIVE AND TEDIOUS. THIS PROJECT INVOLVES U ...
