The Multi Unit Spectroscopic Explorer (MUSE) is a second-generation VLT panoramic integral-field spectrograph currently in manufacturing, assembly and integration phase. MUSE has field of 1x1 arcmin2 sampled at 0.2x0.2 arcsec2 assisted by the ground layer adaptive optics ESO facility using four laser guide stars. instrument large 24 identical high performance integral units, each one composed an advanced image slicer, 4kx4k detector. In this paper we review progress manufacturing report...
An efficient room-temperature self-powered, broadband (300 nm–1100 nm) photodetector based on a CuO–TiO2/TiO2/p-Si(100) heterostructure is demonstrated. The CuO–TiO2 nanocomposites were grown in two-zone horizontal tube furnace 40 nm TiO2 thin film deposited p-type Si(100) substrate. devices exhibited excellent rectification characteristics under dark and individual photo-illumination conditions. showed remarkable photo-response (300–1100 nm) light illumination at zero bias voltage,...
For many applications, the usefulness of millimeter-wave imagers is limited by large aperture sizes required to obtain images sufficient resolution. Sparse techniques could open up wider range applications mitigating volume requirements high resolution imagers. In previous proceedings, we have presented an approach towards realization millimeter-wave, sparse-aperture using optical techniques. By electro-optic modulators upconvert received fields onto carrier, such can be readily captured,...
The Multi-Unit Spectroscopic Explorer (MUSE) is an integral-field spectrograph for the ESO Very Large Telescope. After completion of Final Design Review in 2009, MUSE now its manufacture and assembly phase. To achieve a relative large field-of-view with fine spatial sampling, features 24 identical spectrograph-detector units. acceptance tests detector sub-systems, design calibration unit development Data Reduction Software are under responsibility AIP. optical implies strict tolerances on...
MUSE (Multi Unit Spectroscopic Explorer) is a second generation instrument developed for ESO (European Southern Observatory) to be installed on the VLT (Very Large Telescope) in year 2012. The project supported by European consortium of 7 institutes. After successful Final Design Review now facing turning point which consist shifting from design manufacturing, calculation test, ... dream reality. At start, many technical and management challenges were there as well unknowns. They could all...
Abstract In this study, we present an in-depth exploration of charge transport phenomena and variable photo-switching characteristics in a novel double-perovskite-based three-terminal device. The Cs 2 AgBiBr 6 thin film (TF) was synthesized through three-step thermal evaporation process followed by precise open-air annealing, ensuring superior quality as confirmed structural morphological characterizations. Photoluminescence spectroscopy revealed distinct emissions at 2.28 2.07 eV,...
