Weekly Reporting

Week of November 30 – December 6, 2017

Issues:

none

Accomplishments this week:

The test PLC from SLAC (credit: Matthew Cyterski) was brought online.  The two new Windows PCs built for local/remote PLC programming were also setup.  Remote access from SLAC to JLAB's Linux VDI was successfully tested.  From this secured VDI network, SLAC staff verified access to the Windows PCs.  Additionally, we are constructing an EPICS test to ensure EPICS Channel Access (CA) across these key VLANs.  The three servers have also been delivered and will be installed shortly

Work continues to prepare HPA racks for new waveguide installation. These racks will be raised 2” to accommodate the new waveguide.

Operational Safety Procedure (OSP) for LERF testing of the LCLS-II CMs is progressing well, we are meeting to discuss the radiation assessment on Friday.

Last piece of the cryomodule shuffle is to relocate the C37 module in the zone 2 location, the baseplates were located & grouted earlier this week. All is now ready to move it into position & install U Tubes, this will likely not be cooled down till the spring CEBAF physics run is completed.

CryoCon diode temperature monitor controllers have been ordered, 4 units @ 8 channels; we need 28 so this will allow for 4 spare channels. This is the same unit that is used in the CHL & CMTF.

We had the third review of the cryocan – cryogenic connection box for the CMs, stub-ups contract should be released in early January.

Sketch of the clean room design was sent to vendor for pricing. This will straddle the region between the two CMs.
