Small Exploration for Solar Eruptions (SMESE) is a joint mission between France and China to investigate the two main types of eruption events on the Sun: Coronal Mass Ejections (CME) and solar flares, and their relationship. SMESE will be launched around 2011, providing a unique opportunity of detecting and understanding eruptions at the maximum activity phase of the solar cycle in a wide range of energies. The payload consists of three instrument packages : LYOT(a suit of twoUV and EUV imagers and a Lyman coronagraph), DESIR(an Infra-Red Telescope working at 35 and 150) and HEBS(High Energy Burst Spectrometer ). HEBS aims at observing hard X-ray and gamma-ray emissions from the energetic eruptions on the Sun like solar flares. HEBS consists of three 3 inch diameter by 3 inch long cylinder of LaBr3 scinitillator placed within a well shaped plastics scinitillator anticoincidence shield. It covers energy range from 10 keV to 600 MeV. The energy resolution at 662 keV of HEBS has been measured to be 3.5% full width at half-maximum (FWHM) at room temperature. Such high energy resolution has not been achieved with any of the established inorganic scintillators.
