摘要：

A tracking detector with bundles of capillaries 20-25-mu-m in diameter and 0.4 m long, filled with a liquid scintillator based on the methylnaphthalene with a new dye MBMP, exposed to the 70 GeV/c p+ beam has been studied. An attenuation length of 60-80 cm at distances L > 20 cm is obtained. Hit density on a track at a distance L = 155 mm is n = 4.4 mm-1 and n0 = 9.6 mm-1 at L = 0. A straight-line RMS residual is sigma(tr) congruent-to 30-mu-m, the two track resolution is sigma(tt) = 57-mu-m. The light detected outside the track region (+/-3-sigma(tt)) is 14% of the total detected light.
