<span style="color:black">PPU January metrics were reviewed this week, and overall progress is quite good with a CPI of 1.01 and SPI of 0.98 as we approach the half-way mark of scope complete. The project office is formulating the process for contingency fund
spending and also collecting input for contingency spending applications. </span>

<span style="color:black">Great news this week in the superconducting RF area with the successful testing of a 4<sup>th</sup> helium vessel jacketed cavity. This paves the way to start the first cryomodule string assembly. In the RF area the LLRF effort is
proceeding well with component procurements on schedule and planning for a possible test of the new system to control an installed cavity during beam study periods later this spring. In the Ring area we are examining advice from last week’s beam power limiting
system and are re-assessing when to replace the injection dump window with the beam imaging capable PPU upgrade. In first target systems a change request was processed for the molecular sieve upgrades and a procurement readiness review was held for cryogenic
moderator ortho-para conversion system equipment. Also, the initial PPU target front body fabrication passed acceptance testing at ORNL, which will provide realization of a cost reduction opportunity. Finally tests in the target development lab indicate no
detrimental impact on heat transfer from the stainless-steel vessel due to the presence of the injected gas. Lastly the klystron gallery build out is progressing well, with a target date for substantial completion at the end of this March. Cable pulls and
terminations are in full swing now, in addition to the pipe installation, and preparations have begun for equipment testing.</span></p>

<span style="color:black">As ORNL begins staff vaccinations, I’m hopeful that a new level of COVID safety will soon be with us. Thanks to all carrying on wherever you may be, at home and/or on site. Have a great weekend - jg</span></p>
