This diploma thesis deals with the design and construction of a complete Ferromagnetic Materials Accelerator system based on magnetic reluctance. In particular, the Magnetic Reluctance Accelerator (MRA) is a device that accelerates a ferromagnetic object at very high speeds. The acceleration is based to the utilization of the force developed in the ferromagnetic object due to the magnetic reaction.Before the construction and measurements of the system, the basic principles ofelectromagnetism as well as the operation of MRA were analyzed. All necessary simulations and studies have also been carried out to ensure the maximum possible performance of the device and the longevity of its electronic and metal parts.The system presented in this thesis takes the electricity from a battery, multiplies the voltage and charges a set of electrolytic capacitors. Then through the power electronic, the stored electrical energy from the capacitors is fed to the coils for the purpose of generating a magnetic field, which accelerates the ferromagnetic projectile. For synchronization of the coils with the projectile, the appropriate photoelectric sensors are applied, which activate the specific power electrons required for the serial ignition of the magnetic pulses. The speed of the projectiles are measured by using another photoelectric sensor and a microcontroller andfinally displayed on a screen. This particular subsystem was also the only instrument for measuring the speeds of the Accelerator, and through it a great deal of measurements related to its performance were extracted.
