Description
Summary:The device hereafter described forms focused acoustic pressure pulses excited by a pulsed magnetic field affecting a cylindrical shell. A specific feature of the instrument is its coaxial radiator connected to a capacitive storage through a pulse transformer with a single-turn secondary winding that is used to excite the acoustic pulse. Design versions of the coaxial radiator are considered and estimates for setting design parameters are presented along with the test results obtained on a prototype model. The device can be used in shock-wave medical apparatuses for fragmentation of nephroliths and gall-stones.
