Abstract	To evaluate the efficiency of reinforcing layers in pulsed magnets with different reinforcing materials, reinforcement methods, and sizes by the same standard, evaluation indexes of reinforcement, Reinforcement Ratio and (RR) material Utilization Ratio (UR), are introduced. The RR is used to evaluate the reinforcing ability of a reinforcing layer, and the UR is used to indicate the material utilization ratio of a reinforcing layer. The approximate analytical formulas of RR and UR are derived in the approximation of zero axial stress. Both the approximate formulas can reflect the effects of the radius, thickness of reinforcing layer, and the anisotropy of the reinforcing materials. Two examples about optimizing the magnet design using the indexes are discussed. One is about poly-layer reinforcement scheme for pulsed magnets, which can utilize reinforcement material effectively. The indexes are used to determine the thickness of each layer with different reinforcing materials in this scheme. The other is about dividing conductor layer into thinner layers, which is an effective method for reducing the peak stress in the reinforcing layer, the indexes are applied to optimize the number of layer division.
