| Research Abstract |
We have established a method to fabricate very short period undulators, in order to obtain high energy undulator photons (higher than 10keV with the fundamental harmonic), and developed a plate-type magnet some 100mm long with a period length of 4mm in the longitudinal direction.
A multi-pole magnetizing method was applied to magnetizing this plate: a periodic undulator field (of 4-mm period in this case) was generated by pulsed electro-magnets, and was transcribed into the plate. The magnetization procedure allows the undulator field to be obtained in a very short gap between the pair of opposing plates. We selected 4-mm period since we can generate 12-keV radiation with the first harmonic of this undulator in the 2.5-GeV electron storage ring.
