Fabrication of high-field short-period permanent magnet wigglers
A permanent magnet wiggler is described that has been designed to lase at unusually short wavelengths. Its novel features include the following: all magnets are magnetized parallel to the wiggler`s axis; only two pairs per period are used; the gap occupied by the electron beam is very small; the magnet arrangement is optimized for lasing on the third harmonic; the assembly of the magnets is carried out during continuous measurements of the field integrals; field gradients are measured with equal care; and residual errors are corrected by gluing small correcting magnets to appropriate places. The assembly, testing, and trimming of this wiggler was accomplished in less than a week. The wiggler has been used to lase successfully at 0.375 {mu}m wavelength.
