Hi Ken,

The weekly PPU update is presented below.

Best, Mark



Proton Power Upgrade project: The project office processed several project change requests, reviewed and approved February variance reports, and issued the February monthly report. The RF team began high voltage processing of the phase 2 klystrons, SCL-28C through 30D, with good initial results. Cryomodules 3 & 4 are being prepared for cooldown in a few weeks in the Linac tunnel. The return end can for cryomodule 6 passed leak testing and will be shipped to JLab next week. Cryomodule 5 is being prepared to ship next week to SNS. The dump dipole vacuum chamber was received at SNS. Initial insulation of dump dipole coils 1 and 2 is complete, and ground wrapping has begun. The ring injection dump has been removed in preparation for the installation of the injection dump imaging system. The hydrogen refill system redesign is being finalized, and a final design review has been scheduled in April.
