Second Undulator Installed at HPCAT 16ID

The new undulator operates with the existing one in tandem mode and was successfully commissioned on August 19, 2009. The dual undulator can deliver even brighter x-ray beams to the 16ID-B x-ray diffraction beamline and the 16ID-D x-ray spectroscopy beamline, providing flexibility in selecting x-ray energies while keeping the independent operation of both beamlines. This is the first step of a phased plan for the HPCAT undulator upgrade. More developments are being made toward a canted undulator system with a long straight section.
