Attendance
Thompson, Creel, Dixon, Michalski, Oren,
Arenius is on his way back from Ohio
Agenda and Notes
1. Operations
LINAC
Normal
CHL1
No additional problems from SC1 CC1 mag bearing cabinet. This series of events cost us 16 hours of DT.
CHL2
Normal
One unplanned event resulted in T7 shutdown. Restart went fine.
ESR
One unplanned event where system balancing at high load resulted in a T2 trip. Restart resulted in T1, T2, and first stage compressor.
One planned event to allow Hall C to switch utube configuration. Two day recovery.
Halls are using more than the maximum capacity of the ESR. Use of the transerline is dependent on the issues at CHl1. There was a Directors Review report a number of years ago that deals with this issue.
CTF
Normal
The cryomodule was warmed up and utubes were pulled on Sunday. A few hours later the power outages began. Expander 2A suffered a bearing failure and had to have a flywheel change.
HDR
Normal.
Compressor was accidentally shutdown by maintenance tech. Unit was restarted quickly so cold box did not trip. The feed forward safety signal between the HDR PLC and the magnet PLC told the solenoid to ramp down just in case.
2. Projects
UIM
Shutdown scheduled for Feb 17. We are finalizing the detailed daily work plan.
UITF
Thermosiphon drawings out for approval.
MSU
Working to accumulate the pressure systems documentation.
LCLS2
Cold compressor review in France went well. Only real surprise was the seismic results forced the manufacturer to increase the thickness of the base plates. Smith Group is an A&E firm to help SLAC put together the installation package. SLAC will not be able to get an installation contract in place until ~Sep even though equipment begins arriving in Apr.
Korea
Review went fine. They are still interested in a collaboration
3. Manpower
New engineer arriving next week. He will work 75% of his time on EI&C for LCLS2 and remainder on ESR2. We have a space for him. I will check on computer.
4. Info from Will
1. LN2 contract proposals are in and have been routed to DOE for approval.
2. New director starts Apr 3.
3. Let Will know if anyone approaches us to provide an estimate for installing an LCLS2 module in LERF.
4. Funding could impact summer shutdown schedule possibly forcing the shutdown of CHL2 earlier than the May bill read. Possibly as early as 23 March. We are moving ahead with electrical installation and fabrication of the piping spools for this job.
5. LERF is still hoping to get the medical isotope contract in 18'
5. Other
Machie send out a request asking how many people still use ME10.
Action Items
1. Must keep meeting to no more than 30 minutes
2. Plan the replacement of the SC2 power feedthrus.
Action Item Updates
1. Need to choose 2 engineers to let Kandice Carter come take pictures of for engineers week.
We are going to start preliminary design of the 2K cold box replacement.
2. Investigate possibility of buying another welder (<$6K)
