Subject: [EXTERNAL] PPU weekly update


This week we received the BES charge letter for the September Independent Project Review. This enables us to appropriately focus the review presentations that are being developed and will go through dry runs in mid-July. Presentation templates are available on the project server.



JLab moved to the next phase of return-to-work this week, which will be beneficial to the ongoing PPU cavity testing and cryomodule production.



Cryomodule 11 was moved into the accelerator tunnel this week for installation in the Linac following successful plasma processing in the RF Test Facility. PPU cavity 5 was received from JLab and will be prepared for testing in the horizontal test stand in the cryomodule test bunker. PPU cavity 13 performed well in testing at JLab following additional handling that was intended to validate the cavity assembly process following helium tank installation.



A final design review for the RTBT PPS controls cabinets was conducted, and procurement of these cabinets will begin in June so they can be installed in the winter maintenance outage.



The repaired SCL circulator was returned to SNS this week and is being prepared for high power testing.

Testing of the RFQ/DTL prototype HVCM continued at the Beam Test Facility.



The RATS-II HVAC upgrade was completed, so we now have additional on-site conditioned storage.



Unfortunately, one of the pipefitters engaged in installation work in the klystron gallery was injured this week when his leg contacted a sharp edge on a pipe hanger.  The wound was relatively minor, and the worker returned to SNS after receiving medical treatment off site.  This is a reminder to maintain awareness of nearby hazards, whether carrying out your work at SNS or working on a project at home.



Thanks for your efforts.  Be safe.  Enjoy the weekend.
