New Assessment of maximum speed achievable in a multistage coilgun with identical coils page added to Theorectical section. Limitations for velocity of projectile are investigated for a multistage reluctance accelerator having identical coils. Geometrical parameters of winding are used as basis, assuming an overdamped system fed from large common capacitance.
