Testing G-CLEF Fiber Efficiency: the Impact of using Adaptive Optics
Keywords in English

High-Resolution Spectroscopy
Optical Fibers
Abstract in English
G-CLEF is a state of the art echelle spectrograph for the Giant Magellan Telescope (GMT), expected to be completed for first light. Its good performance for seeing limited observations may be further improved with the future use of an extreme Adaptive Optics (AO) system to cancel out atmospheric disturbances and optimize throughput. The goal of our project is to perform laboratory optical-bench experiments to simulate G-CLEF working with and without AO. We measure the efficiency of the G-CLEF fiber in both cases to compute the gain in using an AO system.

Abstract in Portuguese
O G-CLEF é um espectrógrafo echelle de última geração para o Telescópio Gigante Magalhães (GMT), com previsão de conclusão para a primeira luz. Seu bom desempenho em observações limitadas pelo seeing pode ser aprimorado ainda mais com o uso futuro de um sistema de Óptica Adaptativa (AO) para cancelar perturbações atmosféricas e otimizar seu rendimento. O objetivo do nosso projeto é realizar experimentos de bancada óptica no laboratório para simular o G-CLEF trabalhando com e sem AO. Medimos a eficiência da fibra do  G-CLEF nos dois casos para calcular o ganho gerado pelo uso de um sistema de AO.
