Meeting General Agenda

Jan. 15th 2015 meeting

1. Report relevant updates from 7:50 and 8:00 daily MCC meetings:
   • Accelerator schedule: No daily/weekly MCC meetings. Expected schedule:
   1. Feb. 13 - Feb. 26: Beam restoration (13 days)
   2. Feb. 27 - March 26: Accelerator development. Physics running conditions are similar to Fall 2014: Accelerator has priority. Possible running for Halls A/B/D.
   3. Apr. 3 - May 4: Physics run (Halls A/B/D).
   • Link to accelerator short term schedule
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.
   • The upstream platform is now a hearing protection area. Hall D is a radiation aread. OSL need to be worn everywhere in Hall D.
