  19. 1st Generation Lesson Learned • Management and Contracts • Upfront R&D, Phase A added. • Agreement on use of Management Tools • More ESO-Consortium Partnership • Global approach (including operations), close involvement prior to PAE • Commissioning painful. Early science added. Early involvement Paranal • Technical Aspects • - Instruments have too many modes. • Positive overall evaluation of VLT (HW and SW) standards • Move towards pipelines which produce science products.

D’Odorico)/ INAF Merate, Palermo, Trieste,Catania(Co-PI, R. Pallavicini) • High throughput, matching or surpassing existing spectrographs • Intermediate Resolution ( ~5000-10000) • Simultaneous wavelength coverage from the UV to the H band • Possibly including spectro-polarimetry • Possibly including a mini-IFU (small area spectroscopy and image slicer) • Fast centering and setting-up

  26. 2nd Generation Instruments: X-SHOOTER More than burst: Star Formation at high Z (Fosbury et al.) Emission line galaxies magnified by an intervening cluster provide unique information on star formation history at early epochs. The Lynx galaxy was studied at Keck with ESI and NIRSPEC. Intermediate resolution spectroscopy has provided line intensities and kinematics. Used to infer the properties of the ionizing sources and abundances.Low spatial density. Intermediate resolution, spectral coverage from UV to IR required.
