Superconducting Projectile Accelerator

We report results on the design and testing of superconducting projectile accelerators. The barrel of the projectile accelerator is mainly made of Y1 Ba2 Cu3 O7-x superconductors (Tc = 93K), which is mounted on a copper seat cooled with liquid nitrogen (77K). Before acceleration forces are applied, a magnetised projectile is suspended inside of the superconducting barrel, without touching the walls of the barrel. Electromagnetic coils with the pulse power supply are used to accelerate the projectile successively. Due to the contactless motion of the projectile travelling along the barrel, the kinetic energy of the projectile is close to the magnetic energy provided by the power supply. That is, the efficiency of energy-conversion from the magnetic energy to the kinetic energy is about ninety percent or higher. The entire firing process is controlled by a microprocessor. The detailed system will be described. The experimental results will be presented. The applications will also be discussed.
