Subject: [EXTERNAL] PPU weekly update


With PPU this week the project office processed change requests, including scope for end can repair, and electronics equipment purchases for schedule risk mitigation.  Regarding superconducting cryomodule progress, a leak was located in the return end can that was sent to SNS for repair, and another return end can being fabricated at the vendor should be completed in mid-December. These components are the critical path for cryomodule completion. The newly installed PPU  RF equipment is running, and ready to support operations. The injection dump dipole can only support operation at the 1.05 GeV level, which we will run at in the upcoming run. This magnet is one being replaced by PPU. Importantly the PPU team also took time off to enjoy the thanksgiving holiday with family and friends.
