Development of 10 m Hodoscope Made of Drift Tubes for Cosmic Ray Muon Registration

The 10 m muon hodoscope made of drift tubes with length of 3.7 m and diameter of 52 mm is under development and construction at the NRC Kurchatov Institute—IHEP. In total, 768 drift tubes are grouped into six identical multilayers, each consisting of two tube layers with parallelly placed tubes. The orientation of tubes in adjacent multilayers is orthogonal; thus, the hodoscope has six and six layers of tubes. The mechanical structure, on-chamber electronics, and data acquisition system are described. Expected technical characteristics and some test results are presented.
