[en] The possibility of a PEP detector suitable for both charged and neutral particles is investigated. Such a detector would be well suited to studies of QED, hadronic final states and searches for new particles. The detector would consist of a central solenoidal magnet (conventional or superconducting) with drift chambers for charged particle momentum measurements and an outside system of shower detectors (Pb-glass or liquid argon) to measure both position and energy of the γ rays. High pressure Cerenkov counters can be introduced between the solenoid and the γ detectors in order to identify charged particles with a K-π separation up to 2 GeV/c and a p-π separation up to 4 GeV/c. In addition, at small angles a system of Cerenkov counters, toroidal magnets with internal drift chambers, and shower detectors can be added to measure the momenta and directions of charged and neutral particles
