    A partial list of things to read before the meeting

    Calibration:

    A key reference is the Calibration White Paper . In March 2000, the ASAC called for a calibration plan. Toward that end, two memos have recently been written:

    See Plambeck's memo and Mangum's memo . Please examine the document Proposal for ALMA Front End Optics for one draft design.

    ALG Issues:

    Refer to Plan for an Enhanced ALMA .

    See also Stephane's comments on the ACA and also Morita's work , Al's summary of June 12.and Jack Welch's Choices of Antenna Size and Number for the Atacama Compact Array.

    Receivers:

    Queries from the JRDG.

    ASAC response to ALMA Receiver Subsystem Top-level Requirements and Specifications. The latter document has been revised, and a draft is available as Specifications for the ALMA Front End Assembly.

    Water Vapor Radiometry

    The Cambridge and Onsala groups have proposed the next generation of 183 GHz Line Monitors (PS) and 183 GHz Line Monitors (MSWord).

    Correlator

    Primary reference is the ALMA Construction Project Book chapter on the Correlator ALMA Construction Project Book chapter on the Correlator. See Cost reduction in FX correlator for enhanced ALMA and sensitivity consideration for recent ideas on one alternative. NEW High Performace FX Correlator System for ALMA. Of interest also is the WIDAR Correlator proposed for the EVLA and a suggestion of its use for ALMA by Peter Dewdney and Brett Carlson.

    Polarization

    See Steve Myers' summary of possible specifications on polarization for ALMA. In March, the ASAC provided recommendations , based in part on a document by D'Addario.

    Configurations
