DESCRIPTION:Speakers: Arslan Lukanov (INR RAS)\nThe availability of the ne
 cessary infrastructure is a prerequisite for the proper functioning of the
  detector\, the article describes a magnetic field compensation system and
  a liquid scintillator purification system for a 5-ton prototype of the Ba
 ksan large neutrino telescope. Detectors based on liquid scintillators pla
 y an important role in experiments in neutrino physics and particle astrop
 hysics. Currently\, a liquid scintillator based on linear alkylbenzene (LA
 B) with the addition of PPO (2\,5-diphenyloxazole) and bis-MSB (1\,4-bis(2
 -methylstiryl)benzene) is actively used in large-scale neutrino experiment
 s. High optical characteristics of the scintillator and a low radioactive 
 background are necessary for the effective operation of the detector. The 
 main methods of cleaning liquid scintillators are:\n1. Chromatographic pur
 ification on columns filled with aluminum oxide (Al2O3)\, which removes or
 ganic and radioactive impurities and increases transparency\n2. Water extr
 action to remove radioactive impurities\n3. Vacuum molecular distillation\
 nPhotomultiplier tubes\, especially large-sized PMTs used in the project\,
  are sensitive to a magnetic field. The influence of the magnetic field ha
 s a negative effect on the resolution of the photomultiplier tubes\, and i
 t also affects the jitter in the PMT\, which ultimately affects the accura
 cy of localization of the scintillation flash in the target volume. In thi
 s case\, it is necessary to use a magnetic field compensation system\n\nht
