Topics

  1. Early Science Modes: Originally the plan was to implement only modes which were available on the single baseline correlator at the ATF on the ALMA correlator in Chile. However, the tunable filter bank will almost certainly be implemented on the Chilean correlator, though not at the ATF. Therefore we need to define modes which we would like to have available both for testing and for observing in the early phases of Chilean operations. Please see the document Baseline Correlator + TFB Specs for details. One possibility is a wideband mode for e.g. continuum simultaneous with a narrowband mode for e.g. a spectral line. Please comment; we don't have to be limited to one but without a specific group there could be nearly an infinite number. See ALMA Early Science Modes SCID-90.00.00.00-011-A-LIS.
  2. Total Power Receiver: In The Beginning, there will be normal ALMA receivers on the total power antennas. Eventually we will want receivers with improved stability. There are several possibilities; comment please.
    1. Normal ALMA receiver modified slightly (e.g. detuned).
    2. Correlation Receiver. This would be a special receiver. It should operate in a predefined 'Continuum Band' which we should define in a spectral place as linefree as possible. The design would probably be somewhat similar to that of the WVR correlation receiver design from Cambridge.
    3. Windowed Correlation Reciever. If in a band there is no suitable window, the masking against contaminant line emission could be achieved in the correlator. Correlation done this far down the chain could be advantageous in that it could remove other sources of instability. The price would be complexity. I would imagine that one would only puruse this option should suitably linefree windows not be available.
  3. Frequency Switching -- The commentary on the wiki page and in other places have been consolidated into a document: Frequency Switching on ALMA SCID-90.00.00.00-012-A-SPE which is open for discussion at almaedm.
  4. ACA correlator PDR -- ALMA-J will hold the ACA correlator PDR on 30-31 May. Robert Laing will represent the Science IPT. In the ACA Correlator PDR folder, you will find the CIDL and a format for the Compliance Matrix as well. I hope you have a chance to look at them. Baseline Correlator + TFB Specs
  5. Nutator Requirements discussion has begun. Comments to wiki page please. Telecon to finalize this 1400 UT on 18 May.

News

  • Antenna news -- ATF.

  • Subarrays -- An option has arisen whereby the patch panel could accommodate any or all of the antennas available. See Subarray Wiki
