Abstract

The SOAR Integral Field Unit Spectrograph (SIFS) is fed by an integral field unit composed of a bi-dimensional arrangement of 1300 optical fibers. It has been developed in Brazil by a team of scientists and engineers led by the National Laboratory of Astrophysics (MCT/LNA) and the Department of Astronomy of the Institute of Astronomy, Geophysics and Atmospheric Sciences of the University of São Paulo (IAG/USP). It comprises three major subsystems; a fore-optics installed on the Nasmyth port of the telescope or the SOAR Adaptive Optics Module, a 14-m optical fiber IFU, and a bench-mounted spectrograph installed on the telescope fork. SIFS is successfully assembled and tested on the SOAR Telescope in Chile and has now moved to the commissioning phase. This paper reports on technical characteristics of the mechanical design and the assembly, integration and technical activities.
