The results of the numeral studies of the source of positrons for NSC KIPT are presented. The positrons are to produce from conversion of the 40 MeV electrons. The bunches of such electrons will be provided by the linac LUE-40. The estimations of yield of the positrons, their spectrum, and spatial-angular distribution are produced. The possibility of the spectrum modification with help of the RF resonator adjusted to the sub-harmonics of the RF frequency is proposed. It is shown that the use of such device allows to substantially increase the number of positrons with small energy. It allows to promote efficiency of the moderation process and increase yield of the slow mono energetic positrons. The optimal parameters of conversion target have been defined. The preliminary calculations of the system of forming the positron bunch are presented as well.
