The CW proton linac has a number of important applications; serving as the initial part of a high-energy, high-power linac for an accelerator-driven system is the main of them. Its CW operation mode and a 5-10 mA beam current, however, are limiting factors for the accelerating field. The surface field should not exceed the Kilpatrick field by more than 1.2-1.5 times. This limitation leads to the increase in linac length and beam bunching complexity. The first results of a 2 MeV, 5 mA, CW RFQ, designed for the operating frequency of 162 MHz, are discussed. Beam dynamics simulation results, obtained by using the BEAMDULAC-RFQ code*, are presented. The electrodynamics of the accelerating structure based on the four-vane cavity is discussed. The accelerating cavity design uses coupling windows as was proposed earlier **, but with windows of an elliptical form. Such form allows for better separation of quarupole and dipole modes.
