Kawasaki Heavy Industries, Ltd. (KHI) has designed a compact free electron
laser device that can provide a powerful and tunable (5-16 mu m) light sour
ce. The FEL device consists of a 32 MeV accelerator, a beam transport syste
m with two 25-degree bending magnets, an undulator of 40 periods and 32 mm
period length, and a cavity mirror system. Using some computer codes to opt
imize the beam optics of the accelerator could provide a high-quality beam
for the FEL. (C) 1999 Elsevier Science B.V. All rights reserved.
