Abstract :
A pulse technique is the most convenient method to produce high magnetic fields. The aim of the present work was the determination of an optimal magnet which fulfills additional conditions based on technical or experimental necessities. The program calculates therefore for a certain pulse shape (half sin wave, full sin wave, Crowbar) in the range (α11) up to (α22) taking heat effects into account a set of coils for fixed parameters like a_{1}, V_{c}, T_{A} wire diameter λ, regarding also limits as H \\geq H_{o}, I \\leq I_{o}, \\tau \\geq \\tau _{o}, T_{E} \\leq T_{o}, Q_{E} \\geq Q_{o} (the index o indicates the selectable values). Beside this stresses and strains are calculated by integrating over all Lorentz forces and compared with material dependent limits. The results are shown on a grey scale as a function of α,β. The program looks automatically for the best suited magnet and calculates its time dependant behaviour liKe H(t), I(t), Q(t), T(t) in detail. A comparison between the theoretical and the experimental values was performed on a real magnet. The agreement of 5% shows the validity of the models used for the calculation.
