Changing mass liner system for generation of soft X-radiation

This report is issued in compliance with Clause F.4.2 of Contract 4769M0014-9Y ``Design study for X-ray generation``. In the first report (Clause F.4.1 of Contract) three systems were considered to solve the formulated problem. All of them were designed on the basis of employment of {O}400 mm disk explosive-magnetic generators (DEMG) as an energy source using a high-speed (25--30 cm/{micro}s) liner converging to the axis. The considered systems differs in modes of current pulse formation. For further effort the customer has chosen System 3 with the changing mass liner. In accordance with this fact this report discusses basic theoretical and computational results obtained to date for System 3. Further development of the theory of the considered system is suggested in the context of the series of experiments the ultimate goal of which is to generate soft X-radiation. Basic stages of the effort to generate soft X-radiation are discussed on the basis of the schedule given with consideration of some corrections which occurred when the system type had been selected
