Abstract :
A hybrid helical microwiggler has been designed analyzing its magnetic field by a computational code. It consists of fan-shaped permanent magnets and ferromagnets which are constructed in four layers each period. It is so small that the outer diameter is about 4 cm and periodical length 1 cm. The magnetic field is 3.73 kG for the gap spacing of 5 mm.
