  2. CRIRES+: The CRIRES Upgrade Project Whatis CRIRES? • High resolutioninfraredspectrograph • Installedat VLT UT1 • R~100,000 • YJHKLM • But: only 15 nmwavelengthcoverage CRIRES+: The CRIRES upgrade project Roman Follert Email: follert@tls-tautenburg.de

  3. CRIRES+: The CRIRES Upgrade Project Scientific goals • Searchforexoplanetsaround cool stars • Radial Velocity • Characterizationoftheatmospheresofplanetaryobjectsaround cool stars • High resolution, high S/N spectra • Origin and evolution of stellar magnetic fields => Long wavelengthrangecoverage, high S/N, polarimetry R. Dorn, ESO Messenger June 2014 CRIRES+: The CRIRES upgrade project Roman Follert Email: follert@tls-tautenburg.de

  4. CRIRES+: The CRIRES Upgrade Project What do weneed? • CRIRES+ single shot • Blue boxes: Current CRIRES single shot • Black line: M4 dwarf • Brown line: New gas cell CRIRES+: The CRIRES upgradeproject Roman Follert Email: follert@tls-tautenburg.de

  5. CRIRES+: The CRIRES Upgrade Project Upgrading CRIRES: What do weneed? • Turn CRIRES into a cross-dispersedechellespectrograph • Getsomebetterdetectors • Provide proper wavelengthcalibrationfrom 1-5 μm • Add Polarimetry • Support theinstrumentwithdatareductionsoftware • Refurbishsubsystemsifrequired CRIRES+: The CRIRES upgrade project Roman Follert Email: follert@tls-tautenburg.de

  6. CRIRES+: The CRIRES Upgrade Project CRIRES+: A cross-dispersedechellespectrograph • Gratingwheelwith 6 gratings (YJHKLM) • New CDU Camera 1-5 μm • New slitassembly (0.2 and 0.4 arcsec) andslitviewer • Upgrade metrologysystem CRIRES+ optical design, R.
