Narrow craters have been produced in aluminum-rod targets mounted in the anode of the Nereus electron-beam accelerator (150 kV, 50 kA, 40 ns). These craters (approx. 0.025 cm in diameter), which are characteristically deeper than their diameter and which extend into the electrode materials significantly beyond the classical range of the primary electrons in a relativistic electron-beam diode, were generated by a converging shock wave that melted and fractured the material in the region of shock focus. It is suggested that similar craters seen by other experimenters were also produced by the same mechanism. (auth)
