  Acceleration of magnetic dipoles is carried out by the running gradient of
the magnetic field formed while sequent switching on the current turns.
Magnetic dipoles, with a diameter of sixty millimeters and full length one
meter, are pre-accelerated by using the gas-dynamic method to speed one
kilometer per second, corresponding to the injection rate into the main
accelerator. To prevent the turning of the dipoles by one hundred eighty
degrees in the field of the accelerating pulse and focus them, the magnetic
dipoles are accelerated inside the titanium tube. The magnetic dipoles have
mass two kilograms and acquire the finite speed five kilometers per second on
the acceleration length three hundreds meters.
