DESCRIPTION:Speakers: Arslan Lukanov ()\nThe Baksan large neutrino telesco
 pe is a large-scale liquid scintillation detector under development at the
  Baksan neutrino observatory of the Institute for Nuclear Research of the 
 Russian Academy of Sciences. The detector will employ a large number of ph
 otomultiplier tubes (PMTs). The Earth's magnetic field can significantly a
 ffect PMT perfomance and\, consequently\, the energy and timing characteri
 stics of the detector. Therefore\, a magnetic field compensation system is
  required to ensure stable operation of the photodetectors.\nThe influence
  of the Earth's magnetic field on the Hamamatsu R7081-100 WA-S70 PMT\, sel
 ected for the 5-ton BLNT prototype\, was experimentally investigated. The 
 measurements were performed under controlled magnetic fields generated by 
 Helmholtz coils.The PMT gain\, peak-to-valley ratio of the single-photoele
 ctron charge spectrum\, and transit-time characteristics were studied as f
 unctions of the magnetic field components. The results demonstrate that ma
 gnetic fields of the order of 0.1 G can already affect the PMT response. T
 hus\, developing a magnetic field compensation system is a necessary task.
 \nThe developed system provides an active approach for producing a homogen
 eous compensating magnetic field over a large detector volume.\n\nhttps://
