  A CAMAC mod­ule in­tended for mea­sure­ments of in­stant mag­netic field using coil sen­sor is de­scribed. It is four chan­nel in­te­grat­ing ADC with cur­rent input in which sig­nal in­te­gra­tion time is con­trolled ex­ter­nally and may be op­ti­mized for a given sig­nal. Orig­i­nal tech­ni­cal so­lu­tion al­low­ing to elim­i­nate in­flu­ence of the in­te­gra­tor ca­pac­ity and switches in­sta­bil­ity on over­all ac­cu­racy is de­scribed. The large ac­cel­er­a­tor fa­cil­i­ties in­clude a great num­ber of mag­netic el­e­ments in­ter­act­ing with a beam for a short pe­riod rang­ing from 0.01 ms to 10 ms. For ex­am­ple, this class of el­e­ments in­cludes all the mag­netic com­po­nents of chan­nels for par­ti­cle trans­porta­tion. In ad­di­tion, most of these el­e­ments are op­er­at­ing rarely - once in 1 - 10000 s. For these el­e­ments the most op­ti­mal is the use of a pulse power sup­ply that re­duces the elec­tric power con­sump­tion and which is most im­por­tant, it solves the prob­lem of heat re­moval. Though, the pulse power sup­ply poses some prob­lems in pro­vid­ing the ac­cu­racy of mag­netic field and its mea­sure­ments.
