Abstract : The quartz-crystal transducer has found wide application in measuring pressure profiles of shock waves in solid materials. When using the quartz crystal in this manner, it is necessary to separate the positive plated surface to form two electrodes. This is done by cutting a narrow concentric groove in the surface. The method described in this report is believed to surpass any known method in the conservation of both material cost and manhours. This technique produces a groove with a width between 0.003 inch and 0.005 inch and concentric within 0.0005 inch over the entire diameter. (Author)
