LHCb est l'une des quatre grandes expériences installées sur l'anneau du LHC. Le détecteur a pour but la mesure précise de la violation de CP et de canaux rares de désintégration dans le secteur des mésons B. Le calorimètre de l'expérience est un ensemble de quatre sous-systèmes : le détecteur de pied de gerbe, le ''preshower'' et les calorimètres électromagnétique (ECAL) et hadronique (HCAL). Il est essentiel pour la reconstruction des événements, pour le déclenchement de l'expérience et pour l'identification des électrons et des photons.

This loss is due mainly to recombination; absorption by oxygen impurity seems insignificant. No detectable energy loss has been observed when a particle moves through the crack between adjacent towers. The cross-talk between two adjacent towers was measured a
