Agenda items so far include:

Old Business

(1) Please approve the minutes of the June   Telecon.
(2) The plan for the next face-to-face meeting is:
 Friday Sept 6: Visit Vertex antenna pm  The Vertex antenna is being assembled, see the webcam where the backup structure is just hidden by orange packing crates to the right of the crane.

 View of the Vertex antenna under construction at Summer School 23 June 2002.
  Sept 7-8, meeting
  Sept 9 fly out to next meeting or home
  New Business

(1) Status Report and summary of the meetings which were held in June: (P. van den Bout)
  ACC teleconference;
  AMAC meeting;
  Chile meeting (site issues)

(2) Charges from the ACC to the ASAC and discussion/organisation (Guilloteau; )
  - Site evaluation and stringency - N. Evans

 - Long Baseline Y+ configuration -  See draft recommendation Booth and Yun Configuration liaisons

 - Enhancements to the baseline ALMA instrument -   S. Yamamoto, P. Cox

  The enhancements which are considered by the Japanese radio community are as follows:
  (1) ACA: Twelve 7-meter antennae and four 12-meter antennae including cryo systems, baseline-receiver cartridges, IF and backend systems for them. The four 12-meter antennae are used for calibrating the ACA and also for accurate single-dish measurements. This will enhance the imaging capability of ALMA.
  (2) New receiver bands: Bands 8, 10 and 4. Receiver cartridges for 64 baseline antennae and 16 ACA antennae. This particularly enhances the submillimeter-wave capability of ALMA.
  (3) Second generation correlator: High resolution correlators for the 64+16 antennae. This enhances the spectroscopic capability of ALMA.
  (4) Contribution to infrastructure
  It should also be noted that NAOJ is making its best efforts to obtain a budget to achieve a value very close to the level of 1/3 of a trilateral ALMA project, so as to cover all the enhancements listed as (1) - (4). Finally, it is worth mentioning that the production of antennae of the ACA, i.e. four 12-meter and twelve 7-meter antennae, together with the enhancement of submillimeter-wave capability are considered as being strategically important items in the Japanese budget request.
 

 - Early Science (P. Cox will circulate some thoughts) - P. Cox

(3) Software: Status Report  (Lucas?)

(4) Draft agenda for and organisation of the ASAC  face-to-face meeting.

(5)The next teleconference is nominally 7 August 1430 UT
