Fabrication and Characterization of Graded Cu-Doped Be Shells - Details and Documentation of Our First Attempt

PDF Version Also Available for Download.

Description

We have fabricated by sputtering and characterized a set of step-graded Cu-doped Be capsules. The capsules were made with Cu doped layers of about 0.35 and 0.70 atom % Cu. The total thickness of the coating is about 100 {micro}m. Capsules were removed from the coater for characterization after each layer was deposited. Our ability to produce doped layers is confirmed, and our ability to control the level of doping is excellent. A variety of characterization techniques, both destructive and non-destructive were explored. The surface finish of the sample capsules removed after each layer progressively got rougher, it is likely ... continued below

Our ability to produce doped layers is confirmed, and our ability to control the level of doping is excellent. A variety of characterization techniques, both destructive and non-destructive were explored. The surface finish of the sample capsules removed after each layer progressively got rougher, it is likely that polishing will be necessary to produce capsules that will meet surface specifications. We have learned a great deal from this first effort, both in terms of coating technology and capsule characterization. We are now implementing several changes in the coating system based in part upon our experience with this first effort. The next graded capsule run should begin near the end of October.
