2Slicing the UniverseCCDs for MUSE
- MUSE (Multi Unit Spectral Explorer) is built by a
consortium of European institutes(ESO,
Göttingen, Leiden, Lyon, Toulouse, Zürich). - 2nd 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.
3Compact CCD Head
- Low Frequency Pulse Tube Cooler.
- Standard head for future ESO instruments.
4New General detector Controler (NGC)
Cascode CCD Buffer Stage 2x gain of single buffer Differential output NGC configuration One board per detector
