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.
