【 摘 要 】

Hundreds of target assemblies will be constructed annually for use on NIF or OMEGA in the near future. Currently, we do not have the capability to tomographically characterize the target assemblies at the desired resolution. Hence, we cannot verify if an assembly has been assembled correctly. The Engineering Directorate, through the LDRD program, provided funding to help solve this problem. This report describes the work accomplished by this LDRD ER (tracking number: 01-ERD-093). The main focus of the LDRD was on the research and development of an x-ray imaging instrument. The instrument design was based on a Woelter [1] Type-I design. The LDRD-ER began as a mid-year project in April 2001. After 2.5 years the LDRD-ER was combined with other work to create a new LDRD-SI. The LDRD-SI was terminated in December 2003. The x-ray microscope research and development was never completed. This report describes the work that was accomplished. It includes discussions on the instrument concept, the optical design, mandrel fabrication, instrument fabrication, optic fabrication, and optic testing.
