Instrumental design of the High Resolution Spectrograph (HIRES) for the E-ELT — •Philipp Huke — Institut für Astrophysik, Georg-August Universität Göttingen

The current instrumentation plan for the E-ELT includes a high resolution spectrograph (HIRES). The science cases for this instrument are: the study of extra-solar planets, their atmospheres, Pop-III stars and fundamental physical constants. The resolving power of the spectrograph should be as high as 200.000, depending on the observation modes and the wavelength. The spectral bandwidth shall range from the blue limit of the telescope up to the K-band. It will be covered by four different spectrographs. In this contribution we will present the preliminary design of the spectrograph, the requirements for the calibration unit and *rst solutions how to achieve 1 mm/s at the calibration unit level.
