✦ Synopsis

A new type of scintillation detector for shower arrays is considered. The detector represents an octagonal scintillation assembly with total area 1 m 2 divided into sectors. Thickness of the plastic is 20 mm. The light is collected by wavelength shifter bars to the photomultiplier, which is located in the center of the detector. A solution to ensure the uniformity of light collection for any coordinate is proposed. Front-end electronics of the detector consists of the controller, the measuring part (QDC, TDC), the system of calibration and the HV converter. The data acquisition system is based on CAN-open standard. There is also a system of temperature stabilization that guarantees not more than 0.51 deviation of the temperature of measuring part elements. Measuring electronics allows obtaining the dynamic range from 1 up to 10 4 particles and 1 ns time digitization. The time resolution of the detector is about 3 ns.
