Abstract

Following the success of the UCL Echelle Spectrograph (UCLES) at the Anglo Australian Telescope, we consider the design of a similar facility for an 8m-class telescope. In particular, we explore to what extent the UCLES could simply be scaled up and whether this is indeed the best or most economic approach. Compensation of image rotation is a critical issue, impacting on the choice of telescope secondary f/ratio. The question of prismatic cross dispersion is reviewed in the context of a large instrument, leading to our novel proposal to mosaic the prisms. The impact of the R4 echelle ruling is explored in some detail, with a preliminary instrument scheme being developed for future study. Finally, we present some comments on the relevance of the Baranne white-light pupil concept.
