Mandrel development update [PDF]
, 1999 We report on the progress since January, 1998, in preparing polymer mandrels by microencapsulation for NIF scale ICF capsules that meet the required symmetry and surface finish requirements. During that time we successfully completed our FY98 DOE TDF4.1 milestone of improving the mandrel low mode to meet NIF requirements.
