The MEG spectrometer at PSI

The MEG experiment is designed to search the Lepton Flavor Violating process μ → e + γ [1,2]. This search requires a high intensity muon beam stopping in a thin target with the maximum rate compatible with the background from combinatorial events. ents are analyzed by a high resolution and fast liquid xenon calorimeter and by a spectrometer composed by an array of ultra-light drift chambers (DCH) for momentum measurement and a double layered timing counter (TC) for measuring the e+ time. sign parameters and performance of the spectrometer during the 2008 physics run are described.
