The PS 170 Central Detector

Abstract

The apparatus for LEAR experiment PS 170 has been described in another paper: it has a cylindrical symmetry around a central region, 40 cm high and with a 50 cm radius, where a C magnet establishes a 1.5 T magnetic field. The detector has been designed to measure two electrons final states from the reactions

$$\overline p {p^\to }{e^+}{e^-}$$

$$\overline p{p^\to}\mathop{{V_o}}\limits_{\left|{ \to {e^+}{e^-}}\right.}+neutrals$$

The p̄ momentum ranges between 300 MeV/c and 2 GeV/c.
