<span style="font-size:12.0pt">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.</span></p>

<span style="font-size:12.0pt">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.</span></p>
