PROGRESS ON HIGH-RESOLUTION TRACKING WITH SCINTILLATING FIBERS - A NEW DETECTOR BASED ON CAPILLARIES FILLED WITH LIQUID SCINTILLATOR

摘要

The capabilities of a new detector based on capillaries filled with liquid scintillator have been investigated. Tests have been performed using various scintillating cocktails and readout systems. With the best combinations, and for light propagation over a few centimetres, the hit density is as high as 5 hits/mm. For propagation over distances greater than 10 cm, an attenuation length of approximately 95 cm is measured. A spatial resolution of sigma congruent-to 12-mu-m is obtained with capillaries of 20-mu-m bore.
