Atacama large submm telescope workshop
Date: Fri, 10 Dec 2004 10:32:43 -0600 (CST)


--- Workshop to be held at Boulder during/after URSI meeting. ---
---      (announcement forwarded from Simon Radford)          ---


Colleagues,

Cornell and Caltech have embarked jointly on a feasibility study of a 
large submillimeter telescope on a high site in the Atacama region of 
northern Chile. To identify and discuss promising approaches to the 
technological challenges, the study team is organizing a workshop about 
the proposed telescope in Boulder on Saturday January 8. This will be 
an all day, open workshop to discuss top level telescope requirements, 
technology approaches, and design concepts. The workshop will have a 
mixture of invited and contributed presentations with ample opportunity 
for informal discussion and comments. The project scientists will open 
the workshop with an outline of the overall science objectives and the 
consequent requirements. Brief presentations on particular design 
aspects are welcome.

The workshop will be held at the
    Millennium Harvest House Boulder
    1345 28th Street
    Boulder, CO 80302
    Phone: 303-998-3823

We look forward to seeing you in Boulder. Please let me know if you 
will be able to attend and if you would like to make a presentation.
