Hi Yuri,
As you may be aware, on May 23 at 5pm the utility power will be turned
off in Hall B, for 8 hours. DSG will be switching the Space Frame cRIO
to clean power during the outage, so that the gas controls will not be
interrupted.
Krister is handling the Hall B engineering on-call during this period.
We do not anticipate any issues with gas control, however, Krister needs
a contact person from the HTCC group so that he can be advised on any
unforeseen issues that may arise from the outage.
Can you have someone contact Krister so these details can be worked out.
Additionally, if you have concerns about the outage (as far as gas
supply is concerned), you may want to talk to Denny about having a
rotameter installed in the place of the mass flow controller, or at
least bypassing it. Again, we do not believe there will be any issues
with the system during this time. But if you have questions and
concerns, now is the time to bring them up to the Hall B
Engineering/Mechanical group.
Thanks,
