Energy and Technology Review, April 1987

A short review of five current research projects at Lawrence Livermore National Laboratory is given. New techniques in microfabrication allow the study of new phenomena and the collection of better diagnostic data. High speed gallium arsenide devises and integrated circuits are being fabricated that can measure transient waveforms at a 5 GHz sampling rate. Wide band, integrated optical modulators for the remote measurement of high speed transient signals are being developed. Extensive research on unique high speed high voltage semiconductor devices for detectors and switching applications is being developed. Finally, it has become possible to design and fabricate semicustom, special purpose integrated circuits in less than five weeks. 6 refs., 42 figs., 4 tabs.
