A new technique for the direct measurement of the Gruneisen parameter of elastic materials is presented. The technique employs the measurement of the one‐dimensional thermoelastic response of materials exposed to a pulsed electron beam. The measured values of the Gruneisen parameter for single crystals of both metals and semiconductors are in excellent agreement with thermal values.read more

Dynamics of Pulsed High Current Relativistic Electron Beams
TL;DR: In this article, the authors used Bz and B? (z-pinch) fields to guide the beam through a window into the drift region, where the ionization in the drift section allows the beam to be confined by its own magnetic field.

One‐Dimensional Thermoelastic Response of Solids to Pulsed Energy Deposition
TL;DR: In this article, a generalized form of the Mie-Gruneisen equation of state was used to develop a description of the free surface motion which includes the temperature dependence of the Gruneisen parameter Γ.

TL;DR: In this article, the reproducibility of x-ray production from high-current gas puffs has been investigated and it has been shown that plasma gradients in these high-mass pinches may limit the K-shell radiating mass, Kshell power, and Kshell yield.

Dynamic response of aluminum to pulsed energy deposition in the melt‐dominated regime
TL;DR: In this article, the results of an experimental study of the dynamic response of aluminum exposed to a high-fluence low-energy pulsed electron beam are presented and compared with calculations based on two equations of state (EOS) models for metals in the meltdominated regime.

Effect of heating rate in thermoelastic stress production
TL;DR: In this paper, measurements of thermoelastic stresses were made as a function of heating rate, and good agreement was found with the predictions of the thermo-elastic wave theory.

The dynamic response of solids exposed to a pulsed‐electron‐beam
TL;DR: In this paper, the first measurements of free surface displacement and velocity induced by the absorption of a pulse of electrons in a solid are reported, and the laser-interferometric measurements demonstrate that the dynamic response of materials induced by charged particle interaction can be observed in detail.
