<p class="xmsonormal">This week PPU had a number of significant accomplishments. In the superconducting RF area the second cryomodule from JLab passed the high power acceptance test, and we now have the two cryomodules needed for installation later this summer
ready to go. In the RF area the new low-level RF system was implemented in operations controlling the last superconducting cavity in the linac, and is performing great. In the Ring area the final (third) coil was wound for the first new injection chicane magnet
at our partner FNAL. In the target area the instrumentation for strain measurement and leak detection was installed on PPU test target 2, slated for installation in the upcoming outage. Installation work in the klystron gallery is also proceeding well, with
the new high voltage convertor modulator tank now installed in its enclosure in the gallery.
