See the update from John Galambos. The auxiliary valve stems mentioned are the cooldown valve stems. An issue with galling after many cycles was identified and being addressed.</div>

<p class="x_MsoNormal"><span style="font-size:11.0pt">The PPU project controls team has been processing several change control requests this week. In the Superconducting RF area, w some auxiliary valve stems on the 2 installed cryomodules are being replaced
prior to cooldown next week. In the RF area we replaced a defective installed klystron and the RF equipment needed to power the new cryomodules is now controllable from the control room. The new high voltage convertor module is undergoing a high power run
this week. In the Ring area the first chicane magnet measurements continued at FNAL and tooling is progressing for the new dump septum magnet. Additional klystron gallery installation is proceeding with wave guide and circulator installation for the equipment
needed to support the phase 2 power ramp-up next spring. </span></p>
