Metal coatings for laser fusion targets by electroplating
Metal coated laser fusion targets must be dense, uniform, spherically symmetric to within a few percent of their diameters, and smooth to better than a few tenths of a micron. Electroplating offers some unique advantages including low temperature deposition, a wide choice of elements, and substantial industrial plating technology. We have evaluated electroless and electroplating systems for gold and copper, identified the factors responsible for small grain size, and plated glass microspheres with both metals to achieve smooth surfaces and highly symmetric coatings. We have developed plating cells which sustain the microspheres in continuous random motion during plating. We have established techniques for deposition of the initial conductive adherent layer on the glass microsphere surface. Coatings as thick as 15 mm have been made. The equipment is simple, relatively inexpensive, and may be adopted for high volume production of laser fusion targets.
