Abstract:
The main component of the free electron laser is the ondulator. The computation of the magnetic field generated by the ondulator current implies vector potential evaluations. Besides the numerical computation approach, an other possibility is the analogical simulation. Such an approach is more intuitive and also enables a validation of the numerical simulation. The ondulator consists of an astroidal wire stack. In each wire of the stack the current circulates alternatively from a wire to another. The vector potential mathematical model for a wire uses operations like multiplications, divisions, radicals, trigonometric functions and integrations. These operations were simulated by using an harmonic oscillator (using MC1458 amplifiers), analog multipliers (AD633) and integrators (using MC1458 amplifiers).
