Prior to the Phase II shutdown at the National Synchrotron Light Source (NSLS) in March 1987, a 10-period mini-undulator was used for soft x-ray imaging on the temporary X-17T beamline for six months. During this brief period we gained considerable experience in the use of undulator radiation for high brightness applications, including the use of high power optics, and position feedback. We commissioned a new scanning microscope using high resolution zone plates, and a fast laser interferometer. The microscope made it possible to study zymogen granules (subcellular structures which play an important role in the secretion of digestive enzymes in the pancreas) in an unaltered state: whole, unfixed, unstained and suspended in water. The first images displayed a distribution of material different than that seen in electron microscopy. In addition, fixed and air dried zymogen granules were the subject of Gabor holography. During the Phase II shutdown we made major changes to the entire system. At the present time the installation and commissioning of the new permanent line at beamline X-1A is at an advanced stage. The design, performance and the projected experimental program of this facility is the subject of this paper. 18 refs., 3 figs., 4 tabs.
