摘要: We present the first automated momentum measurement in an Emulsion Cloud Chamber, consisting of multiple sandwiches lead plates and nuclear emulsion sheets. The is based on detection Coulombscattering analysed by so-called angular method. A 3 X0 chamber was exposed to 2, 4 GeV=c p � : pion resolution 36% at GeV=c; 35% 28% for 2 achieved.
