	The program of the ITEP-TWAC Facility upgrade for next three years has been approved last year in the frame of National Research Center Kurchatov Institute taking up ITEP in accordance with government decision. It includes expanding of multimode using proton and heavy ion beams in different applications on a base of new accelerator technologies development. The laser ion source advantage of high temperature plasma generation has to be transformed to high current and high charge state ion beam of Z/A up to 0.4 for elements with A ~ 60 to be effectively stacked in the accumulator ring with multiple charge exchange injection technique. The new high current heavy ion RFQ section is in progress for the beam test. Accelerating system of accumulator ring U-10 is modified to increase compression voltage for stacked beam by factor of four. Design of proton injection and beam slow extraction for UK ring is performed for its utilizing as self-depending synchrotron in medical application and for imitation of cosmic radiation. The machine status analysis and current results of activities aiming at both subsequent improvement of beam parameters and expanding beam applications are presented.

	The 4 vane RFQ resonator with magnetic coupling windows as initial part of high-current Heavy Ion Linac for ITEP TWAC Facility is presently under commissioning at ITEP. It was constructed for acceleration of ions with 1/3 charge-to-mass ratio to the energy of 1.57 MeV/u with beam current up to 100 mA. Additional beam dynamics simulations have been carried out for actual fields of the RFQ in order to determine both extreme output beam properties for different ion species with charge-to-mass ratio in the range of 1-0.25 and limitations for high-brightness of the high-current injector. The beam test of RFQ has been started with protons at relatively low electrode voltage for experimental studying the RFQ beam dynamics. First results of the beam test in comparison with beam dynamics simulations are presented.
