Abstract
The World Space Observatory - Ultraviolet (WSO-UV) is a space astronomy project led by Russia, with contributions from China, Germany, Italy, Spain, United Kingdom and a number of other countries in the world. WSO-UV consists of a 1.7-meter diameter telescope and three focal plane science instruments. The Long Slit Spectrograph instrument on-board WSO-UV will produce moderate spectral resolution (R=1000-2500) spectra in the 102nm ~ 320nm wavelength range along a slit of 75 arcsec in length and 1 arcsec in width. The spatial resolution of the instrument will be ~1 arcsec. A two-channel scheme is proposed to optimize performance, with each of these using a Rowland Circle optical design with Microchannel Plate detectors in the focal plane. We will discuss the detailed design of the spectrograph and its expected performance in this paper.
