“…Time-resolved x-ray spectroscopy 12 indicates that dielectronic satellite radiation is emitted only briefly from the hottest plasma region, whereas resonance radiation persists for a longer period of time in the cooler recombining plasma. Thus the satellite radiation is more characteristic of the hot, dense core region and is less affected by time averaging.…”

electron scattering.In previous reconnection experiments anomalous resistivity has been observed and claimed to be responsible for current disruptions. 11 " 13 However, there the resistivity is calculated only from one component of the fields, i.e., the parallel induced electric field -A y and current density J y . Ignoring space charge fields and three-dimensional effects must lead to erroneous conclusions.

“…15 In a streak camera, photoelectrons are emitted after the cathode is bombarded with X-rays, after which Auger electron decays follow. Inside the photocathode, either elastic scattering, where the electron momentum changes direction, or inelastic scattering, where secondary electrons (SEs) may be excited from the valence band or energy may be lost to the system, can take place.…”

We present a study of the characteristics of secondary electron cascades in two photocathode materials, KI and CsI. To do so, we have employed a model that enables us to explicitly follow the electron trajectories once the dielectric properties have been derived semiempirically from the energy loss function. Furthermore, we introduce a modification to the model by which the energy loss function is calculated in a first-principle manner using the GW approximation for the self-energy of the electrons. We find good agreement between the two approaches. Our results show comparable saturation times and secondary electron yields for the cascades in the two materials, and a narrower electron energy distribution (51%) for KI compared to that for CsI.

“…Early achievements in the study of two-beam-driven implosions included the development and application of new X-ray streak camera based diagnostics, showing the implosion time from streak images [5] and the first streak-time-resolved X-ray spectra [6]. Spaceresolved spectroscopy of implosions [7], linked to new theoretical work on X-ray spectral line shapes, also gave significant results [8].…”
