Integration of Vacuum/Diagnostics with Undulator
ConclusionsCurrent chamber designs are well developed to continue the design of the cradle
Current designs are well integrated together to allow progress to continue
Future designs are going to have interior surfaces of aluminum rather than copper, this will necessitate a new approach to the chamber design
