Scintillation counter with WLS fiber readout

Bukin D. A., Druzhinin V. P., Golubev V. B., Serednyakov S. I.

The parameters of a cylindrical scintillation counter of 126 mm in diameter and 370 mm in length with wavelength shifter (WLS) fiber readout are presented. The fibers are glued into machined grooves along the scintillator. Light from both ends of the WLS fibers is transmitted to separate photomultipliers by 1 m long clear optical fibers. The average total signal, collected from both sides of the counter is equivalent to 8 photoelectrons per minimum ionizing particle. The described cylindrical scintillation counter is a part of inner system of collider detector SND.
