Real-time observation of frustrated ultrafast recovery from ionisation in nanostructured SiO2 using laser driven accelerators

Autor: Kennedy, J. P., Coughlan, M., Fitzpatrick, C. R. J., Huddleston, H. M., Smyth, J., Breslin, N., Donnelly, H., Arthur, C., Villagomez, B., Rosmej, O. N., Currell, F., Stella, L., Riley, D., Zepf, M., Yeung, M., Lewis, C. L. S., Dromey, B.

Ionising radiation interactions in matter can trigger a cascade of processes that underpin long-lived damage in the medium. To date, however, a lack of suitable methodologies has precluded our ability to understand the role that material nanostructur

Melting and phase change for laser-shocked iron

Autor: White, S., Kettle, B., Lewis, C. L. S., Riley, D., Vorberger, J., Glenzer, S. H., Gamboa, E., Nagler, B., Tavella, F., Lee, H. J., Murphy, C. D., Gericke, D. O.

Using the LCLS facility at the SLAC National Accelerator Laboratory, we have observed X-ray scattering from iron compressed with laser driven shocks to Earth-core like pressures above 400GPa. The data shows shots where melting is incomplete and we ob

A novel method for characterising the full spectrum of deuteron ions emitted by laser driven multi-species ion sources is discussed. The procedure is based on using differential filtering over the detector of a Thompson parabola ion spectrometer, whi

A scheme has been developed permitting the spatial and temporal characterisation of ultrafast dynamics induced by laser driven proton bursts in transparent dielectrics. Advantage is taken of the high degree of synchronicity between the proton bursts
