Abstract :
A 30 mm long spectrometer made of three emulsion sheets inside a compact permanent magnet has been tested with secondary beams produced by the proton synchrotron at KEK. A momentum resolution of σ ( p ) / p = 13.3 ± 0.3 % has been obtained in the momentum range from 0.5 to 2.0 GeV/c, using the sagitta measurements of the tracks reconstructed with an automated emulsion readout system.
