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