SDW 2005, TaorminaReiss et al., Slicing the Universe2 Slicing the Universe CCDs for MUSE MUSE (Multi Unit Spectral Explorer) is built by a consortium of European institutes (ESO, Göttingen, Leiden, Lyon, Toulouse, Zürich). 2 nd generation instrument for the VLT. Integral field spectrometer for the Nasmyth focus. 24 Integral Field Units (IFU). 24 cryostats with one 4k x 4k CCD attached to IFUs.
