A Pellet Accelerator and Injector device to accelerate a cartridge, loaded with pellets of solid material, comprising a core system and a peripheral system; wherein the core system comprises a vacuum sealed enclosure, one or more linearly arranged, current carrying hollow bore Electromagnets that drive the Cartridge, an insulating Barrel through which the cartridge moves, the Cartridge that carries the pellets within itself and offload them through impact-induced separation process at the muzzle of the barrel and a Stopper at the muzzle of the barrel, that stops the cartridge and detaches it from the pellets and all these components are mounted on support structures; and wherein the peripheral system comprises power supplies for the electromagnets to apply electrical voltage and drive current through, switches that connect the Power supplies to the electromagnets, a velocity measurement system, and a Master Control hardware that acts on the feedback from velocity measurement system and synchronizes the coil switching; characterized in that the electromagnet, namely a coil carrying a time-varying current (I p), is used to generate magnetic fields inside the coil directing along the axis of the coil (B z) and along the radius (B r) and on closing the switch in a circuit formed by the coil and the power supply, the time varying current (I p) flowing through the electromagnet creates the time varying axial magnetic field (B z) that induces an electric potential on the cartridge placed within it, in a contactless way resulting a secondary current (I sec) to flow circumferentially on skin of the conducting cartridge and the secondary current density (J sec) on the cartridge and the radial magnetic field (B r) of the electromagnet together generate an electromagnetic force, F z, that accelerates the cartridge loaded with pellets within it. wherein the core system comprises a vacuum sealed enclosure, one or more linearly arranged, current carrying hollow bore Electromagnets that drive the Cartridge, an insulating Barrel through which the cartridge moves, the Cartridge that carries the pellets within itself and offload them through impact-induced separation process at the muzzle of the barrel and a Stopper at the muzzle of the barrel, that stops the cartridge and detaches it from the pellets and all these components are mounted on support structures; and wherein the peripheral system comprises power supplies for the electromagnets to apply electrical voltage and drive current through, switches that connect the Power supplies to the electromagnets, a velocity measurement system, and a Master Control hardware that acts on the feedback from velocity measurement system and synchronizes the coil switching; characterized in that the electromagnet, namely a coil carrying a time-varying current (I p), is used to generate magnetic fields inside the coil directing along the axis of the coil (B z) and along the radius (B r) and on closing the switch in a circuit formed by the coil and the power supply, the time varying current (I p) flowing through the electromagnet creates the time varying axial magnetic field (B z) that induces an electric potential on the cartridge placed within it, in a contactless way resulting a secondary current (I sec) to flow circumferentially on skin of the conducting cartridge and the secondary current density (J sec) on the cartridge and the radial magnetic field (B r) of the electromagnet together generate an electromagnetic force, F z, that accelerates the cartridge loaded with pellets within it.
