GENERAL DESCRIPTION:	BL4-3 is dedicated to x-ray absorption spectroscopy measurements with special capabilities for soft-energy (2.4-6 keV) studies in addition to hard x-rays.  Equipment includes multi-array Ge detectors, LHe cryostat and soft x-ray instrumentation. Applicationas include mainly MEIS, biology and materials science, with some use in chemistry andphysics. This station enables soft x-ray measurement (from S K-edge and up).
