#*Power to transformers T5 and T7 will be briefly shut off at 1:15pm tomorrow 16 Jan 2015.  This means all of the clean power in Hall D (Bldg 202) and all of the power in the Counting House (Bldg203) will be off; except of course anything connected to a UPS.  The total outage time is expected to be less than 30 minutes. If you need to do a controlled power off on your equipment please do so.  Once the power is restored I will send out another e-mail to let

  2. Report on Work in the Hall:
    • If you have work to do in the Hall, please notify Tom (Hall work coordinator) and if necessary, document it in the electronic logbook.
    • OSL need to be worn everywhere in Hall D.
  3. Hot Check OUT Status 13% ready ; 68% checked ; 18% not ready
