TECHNICIANS ARE ASSEMBLING THE VACUUM ULTRAVIOLET RING.

THE NSLS WILL ACCELERATE AND STORE ELECTRONS AT A SPEED CLOSE TO THAT OF LIGHT TO PRODUCE AN ENTIRE SPECTRUM OF RADIATION, FROM INFRARED THROUGH X-RAYS, FOR UNIQUE APPLICATIONS IN MANY FIELDS OF SCIENCE. THE FACILITY WILL CONSIST OF TWO ELECTRON STORAGE RINGS. THE SMALLER RING WILL ACCELERATE ELECTRONS TO 700 MILLION ELECTRON VOLTS TO PRODUCE ULTRAVIOLET RADIATION, AND THE LARGER RING WILL ACCELERATE ELECTRONS TO 2500 MILLION ELECTRON VOLTS TO PRODUCE X-RAYS. THE ULTRAVIOLET LIGHT CAN BE USED TO STUDY: CHEMICAL REACTIONS AND STRUCTURES, THE PROPERTIES OF PURE METALS, ALLOYS, AND INSULATING MATERIALS, AND THE TRANSFER OF ENERGY IN BIOLOGICAL SYSTEMS. X-RAY LITHOGRAPHY MAY BE USED BY THE ELECTRICAL INDUSTRY IN THE PRODUCTION OF MICROSCOPIC PRINTED CIRCUITS FOR COMPUTERS AND MICROPROCESSORS. X-RAY MICROSCOPY COMPLEMENTS ELECTRON MICROSCOPY, PERMITTING OPERATIONS THAT WOULD BE IMPOSSIBLE WITH AN ELECTRON MICROSCOPE.
