DESCRIPTION:Speakers: Rinat Fakhrutdinov (NRC "Kurchatov institute" - IHEP
 )\nThe conceptual design of the SPASCHARM facility [1] calls for its reloc
 ation to channel No. 24 of the U-70 Accelerator Complex\, with a muon dete
 ctor positioned at the end of the facility. This detector is required to i
 dentify J/ψ particles via their decay into two muons (μ+μ−) and subse
 quently to search for χc2 (spin 2) and χc1 (spin 1) through their decays
  into J/ψ + γ\, with the ultimate goal of measuring the gluon contributi
 on to the proton spin. This paper presents the concept for the muon detect
 or's construction. The proposed design comprises three pairs of tracking p
 lanes with a total area of ~12 m²\, interleaved with steel filters assemb
 led from disks approximately 4 m in diameter and 220 mm thick. Each pair o
 f tracking planes consists of two identical planes oriented orthogonally t
 o one another\, and each such plane is in turn composed of two layers of d
 rift tubes housed in aluminum tubes 3.7 m long with an inner diameter of 5
 0 mm.\nOpenings of ~20 × 20 cm² are provided in the central regions of t
 he steel disks and tracking planes\, coaxial with the primary proton beam\
 , to prevent the tracking planes from being overloaded by primary protons 
 and the products of their interaction with the steel disk material.\n\nhtt
