1. MLC Schedule Plan
Proven in-house expertise and infrastructure for fabrication, assembly, and testing cryomodules
Confident in our technical expertise and planning as we’ve been through:
4 ERL HTC builds
2 ERL ICM builds
Numerous CESR B-Cell Cryomodule builds
Learned from past program efforts and work hard to implement program changes with eye towards efficiency

4. MLC Schedule - Points for Success
EBW in the near term (6 months) for cavity production
(Reliability of EBW equipment and volume of welds)
Finalizing all design details (resources)
Accounting for and ordering purchased items (incl fasteners)
Controlling delivery of long lead time purchased items
Controlling vendor fabrication (QC and delivery)
Coordinating internal resources
