摘要：

The detector of the E865-collaboration at the Brookhaven-AGS described here combines a magnetic spectrometer for the charged decay products of 6 GeV/c K+ with excellent electromagnetic calorimetry and efficient particle identification for electrons and muons. Its high-resolution, large acceptance and high rate capability made it well suited for the study of extremely rare or forbidden decays with multi-leptonic final states such as K+-->pi(+)mu(+)e(-), K+-->pi(+/+/-), K+-->nu/e(-)/e(+)e(-) and K+-->pi(+)pi(-)e(+)nu(e), down to branching ratios below 10(-11) in an intense K+ beam (approximate to 10(8) per AGS spill).
