Paper Abstract

A three stage superconducting undulator (modulator, dispersive section, and radiator) is under construction at the National Synchrotron Light Source--Accelerator Test Facility at Brookhaven National Laboratory in collaboration with Grumman Corporation. A novel undulator technology suitable for short period undulators (6 - 40 mm) is employed that offers (1) high magnetic fields on axis at short periods, (2) as easily varied field, (3) a variable dispersion, (4) a variable magnetic field taper to ensure optimum resonance between the electrons and the radiation field, (5) transverse focusing to prevent electron beam emittance growth, and (6) low random field errors (below 0.3% rms) as machined and assembled, without shimming or trimming.
