N2 - A novel method to fabricate undulator magnets of a-few-millimetre-period length is being explored. Plate-type magnets, 100mm-long with 4mm-period length, have been successfully fabricated. They produce an undulator field of approximately 3kG at a gap of 1.6mm. Prototype undulators based on this technology have been constructed. Field measurements and characterization show that the quality of the undulator field of these plate magnets is sufficient for an undulator light source, and the calculated spectrum shows that the fundamental radiation emitted from this field is quite satisfactory. Test experiments for light generation using a real electron beam have been carried out at a test accelerator at the Research Center for Electron Photon Science (ELPH), Tohoku University, Japan, which is able to realize optics conditions to accept a very short gap of ∼1.6mm. First observation and characterization of blue light was successfully accomplished.
