Superconducting free electron laser |
摘要 |
An improved free electron laser is described. The laser comprises an accelerator arranged in order to emit an electron beam along a laser emission line and a circuit loop including a curved line which traces a periodic function along a line parallel with said laser emission line in order to produce a periodic magnetic field along said laser emission line. The periodical circuit is made of a superconducting material, so that the periodical length thereof is made as short as 100 microns without compromising the strength of the magnetic field induced by the circuit.
