Abstract
A new type of helical wiggler consisting of two staggered-iron arrays inser
ted into a solenoid field has been developed. The field measured by a test
wiggler showed linear increment with the period. It was seen that 24% of th
e solenoid field contributed to the induced wiggler field when the gap leng
th and the period of the wiggler were 16 and 24 mm, respectively. This wigg
ler would be useful for an FEL with a low-energy electron beam propagating
in a strong axial guiding field. (C) 1999 Elsevier Science B.V. All rights
