27 Jun 2000 | | Subject: | astro-ph | | Affiliation: | AAO and U Sydney), K. Taylor (AAO), I.K. Baldry (AAO), P.R. Gillingham (AAO) and S.C. Barden (NOAO | | Abstract: | We are proposing a new spectrograph (ATLAS) which would revolutionise intermediate-dispersion observations at the AAT. Based on the new technology of Volume Phase Holographic gratings, and using transmission optics, ATLAS offers high throughput and a wide field (24’). It will be ideally suited to extensive surveys of faint objects. It has been designed with a collimated beam diameter of 150 mm, giving resolution lambda/delta lambda up to nearly 10,000 with a 1.5 arcsecond slit and good efficiency. It will be a dual-beam instrument, to maximise observing speed and allow optimised optical coatings to be used. The project is working towards its Concept Design Review which will occur during 2000. | | Source: | arXiv, astro-ph/0006378 | | Services: | Forum | Review | PDF | Favorites | |
