Abstract

The Fabry-Perot (F-P) velocimeter is our main diagnostic tool for hypervelocity impact experiments with the electric gun. Because of its immunity to electromagnetic interference F-P velocimetry is well suited to studying the performanceof flyers providing data on velocity calibration acceleration characteristics and material erosion as well as spallation of various materials under high-velocity impact measurement of impact pressure pulses and Hugoniot measurements of composite materials. We present results and data from selected experiments and compare them with code predictions. 1.
