Soft-x-ray imaging with the 35 period undulator at the NSLS

Abstract

In the summer of 1988, the National Synchrotron Light Source installed a 35 period soft-x-ray undulator. We are using this device as a radiation source for a beamline designed for soft-x-ray imaging experiments that require high brightness for practical operation. We present the design philosophy and implementation of this beamline. Preliminary characterization of the beamline and undulator indicate that the central intensity of the undulator is within a factor of 2 of design. We have measured an intensity of more than 1015 photons/s/0.1% BW/mrad2 at 36 Å. The monochromator has achieved its design resolving power of 2000.
