1 Old Business The enhanced Agenda from the last meeting is available. Science IPT notes from the last telecon are not available.

  1. New Business--Project news/updates.(Hills, Peck)
    • For a recent summary see October 2010 Science section of ALMA report
    • Outcomes of the Reviews. See collection.
    • Science_Milestones_-_31Oct2010.pdf: Science Milestone update; end of October
    • AAER, Board meeting and the Call for Proposals for Early Science
    • Configurations for Early Science
      • A compact configuration has been designed by F. Boone
      • ES Spectral modes
    • Commissioning news. Eight antennas remain available after a move of DV08 to the AOS at pad T703. The array now consists of DV02 in pad J504; PM02 in pad T701; DV03 in pad N605; DV04 in pad T702; DV05 in pad J505; DV06 in pad T704; DV07 in pad J510; DV08 in pad T703. We are calling this the "Initial Commissioning Array" configuration. This allows good tests of e.g. antenna performance at different elevations. We expect to have 9 antennas later in the year; 16 by May.
  2. Change Requests and other technical items.
    • CCB Minutes
    • 260. Relaxation of the Band 3 polarization efficiency specification
      • CRE Number : ALMA-40.02.03.00-0662-A-CRE Relaxation of the Band 3 polarization efficiency specification (ALMA-40.02.03.00-0662-A-CRE) - APPROVED 23 November 2010 with the following wording:
        • Relaxation is sought to the FE Requirement [FEND-40.00.00.00-00226-00 / AT] which requires that the polarization efficiency of the tertiary optics system shall exceed 99.5% for all ten bands. The proposed relaxed requirement (for Band 3 only) is 99% (-20 dB cross polarization in the integrated sense.) The peak cross polarization for the cold cartridge alone (without warm optics), [FEND-40.02.03.00-00298-00 / T], is sought to be relaxed to -21 dB instead of the presently specified -23 dB.
        • Action item: Eduardo Pizarro to modify CRE and gather relevant signatures
        • Action item: Band 3 team to provide information as the cause of the variable cross polarization performance - 30 Nov (one week) due date.
