Abstract: The present invention relates to the field of electromagnetic rail launchers, and particularly to a rail launcher and an associated projectile-launching process including at least two longitudinal rails connected to a power supply circuit of these two rails, these rails being at least partially surrounded by superconductor elements able to generate a magnetic induction of a direction perpendicular to the plane formed by the rails and located therebetween during the flow of a current therein, launcher wherein the supply circuit includes the superconductor elements.

Abstract: The invention relates to a supraconductive coil transition detector comprising means for disconnecting the detector directly before a coil discharge phase. The detector comprises a resistive divider (R1, R2) arranged in parallel on the supraconductive coil (1), the middle point A of the supraconductive coil and the middle point (B) of the resistive divider being connected to the two inlets of a threshold comparator. The connection means comprise switches (31-33) arranged on the connections between the coil and the detector, and means for opening said switches as soon as the comparator supplies a signal above a threshold.
