	The new linac for A/Z = 8, output energy 4 MeV/u and 3 mA current is under development at NRC "Kurchatov Institute"-ITEP. The linac consists of Radio-Frequency Quadrupole (RFQ) with operating frequency 40 MHz and two sections of Drift Tube Linac (DTL) with operating frequency 80 and 160 MHz, correspondently. Both DTL has a modular structure and consists of separated individually phased resonators with focusing magnetic quadrupoles located between the cavities. The DTL₁ is based on the quarter-wave resonators meanwhile DTL₂ is based on IH 5-gap resonators. The 6D beam matching between RFQ and DTLs is provided by magnetic quadrupole lenses and 2-gaps RF-bunchers. The paper presents results of the radio-frequency (RF) design of linac accelerating structures.
