DESCRIPTION:Speakers: Eduard Ginya (JINR)\nThe development of efficient an
 d cost-effective muon detection systems is an important task for future ci
 rcular lepton colliders such as CEPC and FCC-ee. Within the R&D program fo
 r the AGORA detector concept\, a scintillator-based muon system with wavel
 ength-shifting (WLS) fiber readout is being investigated. The performance 
 of such a detector depends on the scintillator geometry\, the method of WL
 S fiber integration\, and the optical transport properties of the scintill
 ator and fiber.\nIn this report\, experimental and Monte Carlo studies of 
 scintillator strips with Kuraray Y-11 double-clad WLS fiber readout are pr
 esented. The light yield was measured for strips of various geometries to 
 compare their optical performance. A dedicated study using extruded strips
  with 10×40 mm² cross sections from different manufacturers\, with diffe
 rent fiber integration methods\, determined the effective length of the WL
 S fiber segment where photon capture occurs\, found to be approximately 4 
 cm — a result reproduced by an optical Monte Carlo model in good agreeme
 nt with the experimental data.\nMonte Carlo simulations were also used to 
 study the timing characteristics of photon propagation in double-clad Kura
 ray Y-11 WLS fibers\, comparing 1 mm and 2 mm fiber diameters as well as s
 traight and loop configurations.\nThe obtained results characterize the in
 fluence of strip geometry\, fiber integration methods\, and fiber configur
 ation on light collection and photon timing\, providing experimental and s
 imulation input for the optimization of scintillator strips and WLS fiber 
 readout for the future AGORA muon system and other physics facilities.\n\n
