AbstractAbstract
[en] DEKOR coordinate detector represents a multilayer system of polymer streamer chambers placed around NEVOD Cherenkov water calorimeter. The basic characteristics of the detector are as follows: area is about 100 m2, angular resolution of about 1 deg, spatial resolution is about 1 cm. Paper presents the detector design, structures of data acquisition system and of a trigger system, as well as, the results obtained in the course of a pilot mounting (8 layers of chambers, working area is 8.4 m2). Measurements using a full-scale facility will ensure the possibility of qualitative investigation into the parameters of muon groups and into mechanisms of their formation

Координатный детектор ДЕКОР представляет собой многослойную систему пластиковых стримерных камер, расположенных вокруг черенковского водного калориметра НЕВОД. Основные характеристики детектора: площадь ≅ 100 м2, угловое распределение ≅ 1 град., пространственное распределение ≅ 1 см. Приведены структуры детектора, системы сбора данных и триггерной системы, а также результаты, полученные при работе пилотной сборки (8 слоев камер, рабочая площадь - 8,4 м2). Измерения с полномасштабной установкой обеспечат возможность количественного изучения параметров групп мюонов и исследования механизмов их образованияOriginal Title

AbstractAbstract
[en] The large area coordinate detector (DECOR) represents a multilayer system of plastic streamer tube chamber modules surrounding the Cherenkov water calorimeter NEVOD. Experimental data collected during the test expositions of first DECOR supermodules (8 vertical planes with 8.4 m2 working area) have been analysed, angular and spatial reconstruction accuracies have been estimated. The procedure of the selection of events corresponding to detection of parallel tracks (muon bundles originated in the atmosphere) is discussed
