Acceleration of magnetic dipoles by a sequence of current-carrying turns

Magnetic dipoles are accelerated by a running gradient of the magnetic field that is produced by sequentially energizing current-carrying turns. Magnetic dipoles $d_{\mathrm{sh}}$ = 60 mm in diameter and $l_{\mathrm{tot}}$ = 1 m in length are gasdynamically preaccelerated to velocity $V_{\mathrm{in}}$ = 1 km/s, with which they are injected into the main accelerator. The turnover of the dipoles in the field of an accelerating pulse is prevented and focusing of dipoles is provided by directing the dipoles into a titanium tube. The weight of the dipoles is $m$ = 2 kg, and they acquire final velocity $V_{\mathrm{fin}}$ = 5 km/s over acceleration length $L_{\mathrm{acc}}$ = 300 m.
