Closed Action Items


Items of Discussion


Resumption of FEL commissioning is planned to begin 2 Feb 98, although this date could slip a few days depending on CHL availability. Please remain calm.

We reviewed progress on the remaining key tasks that need to be accomplished prior to resuming commissioning:

G. Krafft mentioned that a current-monitor (and M_55) cavity has been installed on the injection line prior to the X-chamber, and cabling is in place. This will be a nice, independent, calibrated diagnostic for current measurements.

There was considerable discussion on scheduling. Bohn invited everyone to e-mail R. Walker, with copy to Bohn, in cases where there are personal preferences or constraints that need to be considered. Bohn also reminded everyone that the strategy continues to be always to have a solid two-week plan that will be documented on the white board in the FEL break room, as well as a three-month projection. We will work out the details as we go and will try to be accommodating insofar as is possible.

R. Legg advised that he completed the Procedure for CW Setup for First Light and all that remains is to post it on the Web.

C. Bohn relayed a memo from J. Boyce saying that the DOE site office and the Accelerator Division have agreed that the FEL Accelerator Readiness Review will need to be held in early May prior to conduct of user experiments. This means all WBS managers and other affected parties will need to begin doing the ARR assessment soon. Boyce will set up a refresher workshop, which all present agreed should ideally be in late February (post-GEN) or perhaps March.
