Abstract

Parameters of modern experimental set-ups depend on the precision of the magnetic field monitoring under real experimental conditions. As a rule, the conditions of modern experiments (ATLAS, CMS, ALISE, LHC-B) have their special requirements to radiation hardness of the magnetometric apparatus. Specialized magnetic-calibration stands have been manufactured to investigate magnetic field sensors for radiation hardness at the Joint Institute for Nuclear Research (JINR) and at the State University "Lviv Politechnic" (SULP). Characteristics of different magnetic field sensors were studied before and after exposure. The sensors were irradiated at the IBR-2 reactor, JINR, by fast neutrons with the mean energy =1.35 MeV up to the fluence of 10/sup 19/ n/m/sup 2/.
