4. 4 One approach to a problem: Keep doing what you’re doing… and hope no one will notice

5. 5 “Genius is one percent inspiration and ninety-nine percent perspiration.”..... Thomas Edison We are going to perspire and inspire We have an excellent R&D program to understand the behavior of solid tungsten armor. We need to allow for innovative concepts that may lead to a first wall solution magnetic intervention engineered walls advanced armor/chamber concepts Special discussion period on first wall (and MI dump) “armor” concepts

6. 6 Thanks Camille...and good luck!
