Abstract
A version of the short-period undulator scheme suggested earlier [A.A. Varfolomeev et al., Nucl. Instr. and Meth. A318 (1992) 809] was inves tigated experimentally and by simulations. Transverse magnetic field c omponents are provided with this scheme by a redistribution of an exte rnal magnetic field supplied by a solenoid similar to that suggested b y A.H. Ho et al. (Nucl. Instr. and Meth. A296 (1990) 631]. An enhancem ent is achieved with an additional set of permanent magnet blocks. 2D simulations using the PANDIRA code and experimental tests with prototy pe magnets have shown that field values B(w) > 8 kG for a period lambd a(w) = 4.5 mm with a 1.5 mm gap can be obtained with a two times lower solenoid field, B(s) = 4 kG. The undulator scheme looks very promisin g for microundulators.
