    abstract

    son, 1981) (fig. 2) is the simplest form of a linear dc-motor with only one current loop. One part of the bucket functions as a conductor between the two rails. The magnetic field is generated by a high current impulse which also generates the electric field. In most cases the conducting armature will spontaneously become a plasma by the current after the power is applied. In a mass-driver the bucket incorporates a coil functioning as a magnetic dipole travelling along the accelerator coils loaded by an ac-current. The phase of the current flow is different from coil to coil (see fig. 3) (O'Neill, 1981)). The mass-driver can operate in a "push and pull" mode with only one accelerator coil active at a time or in a "pul 1-only"-mode with a few active coils with unidirectional current-flow of different amplitudes. The "pulI-only"-mode provides magnetic flight of the bucket, so mechanical contact between driver and bucket can be avoided.
