The Gemini Project is an international partnership to construct and operate two 8-meter optical-infrared telescopes, one on Mauna Kea, Hawaii and the other on Cerro Pachón, Chile. The sites were chosen to provide good access to both hemispheres, in optimal conditions for optical and infrared observations, where an astronomical infrastructure already exists. Although the telescopes will be identical, their initial instrumentation will differ because of both scientific and financial considerations.
As this is the first annual report of the Gemini Project, a full description of the Project and a summary of the scientific investigations to be undertaken with the Gemini telescopes is of interest. An illustrated brochure entitled The International Gemini Telescopes, containing such a description, has been prepared for distribution to the public.
|United States||National Science Foundation (NSF)||50%|
|United Kingdom||Particle Physics and Astronomy Research Council (PPARC)||25%|
|Canada||National Research Council (NRC)||15%|
|Chile||Comisión Nacional de Investigación Científica y Tecnológica (CONICYT)||5%|
|Brazil||Ministry of Science and Technology (MST)||2.5%|
|Argentina||Secretaría de Ciencia y Tecnologia (SECYT) & Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET)||2.5%|
Each partner contributes the indicated share of the capital construction cost, and receives in return a proportionate share of observing time on both telescopes. Since the northern site is provided by the University of Hawaii, a share of the observing time at that site will go to the University of Hawaii. Similarly, since Chile has supplied the southern site, an additional share of the observing time at the southern telescope will go to Chilean astronomers.
In addition to observing time, the intellectual value involved in designing and constructing the telescopes is also shared among the member nations.
All first-generation instruments will be located at the f/16 Cassegrain focal platform. The planned baseline instrumentation is:
|Mauna Kea||Cerro Pachón|
|Optical Acquisition Camera||Optical Acquisition Camera|
|Multi-Object Spectrograph (UK/Canada)||Multi-Object Spectrograph (UK/Canada)|
|1-5µm Imager (U. of Hawaii)||High Resolution Optical Spectrograph (UK)|
|1-5µm Spectrograph (US NOAO)||Shared Instrumentation with CTIO|
|8-30µm Imager (US) (May be shared between Gemini North and South)|
|CFHT Fiber Feed|
