This spectrograph will be optimized for faint supernovae and galaxies in a 3×6 arsec2 at low spectral resolution (R~100) through the wavelength range (0.35-1.7 mum). The integral field method is based on glass image slicer. A prototype of this instrument has been build to validate the concept

The simulation is then applied to the study of the bunch crossing identification at LHC. We present the performance of different pulse shapings and processing algorithms in the LHC environment.

SN2005gn is a Type IIn supernova at a redshift of z = 0.0397, with prominent H- alpha (FWHM 4000 km/s) and Ca II IR triplet emission.
