Cylindrical reflex triodes (CRTs) driven by a pulsed power generator can produce relatively low-endpoint X-ray spectra (~250 keV) that can be suitable for certain radiation–matter interaction studies. CRTs have several advantages over other reflex

A new technique can determine far-field X-ray spectra produced by intense pulsed electron beams (e-beams). Dose-rate measurements at three different angles of observation determine the e-beam voltage, current, and angle of incidence, all as functions

Naval Research Laboratory is starting to study the connection between plasma instabilities and fast ion acceleration for neutron production on a dense plasma focus (DPF). The experiments will be performed on the HAWK generator (665 kA) that has a fas

Intense electron beams striking a high-atomic number target produce high-output pulsed photon fluxes for flash x-ray experiments. Without an external guide field, such beams are subject to the dynamics of high-current electron beam propagation, inclu

The small community of physicists concerned with flash x-rays, short pulses of intense hard bremsstrahlung with photon energies exceeding hundreds of keV, is always on the lookout for new detector materials and protocols to diagnose such radiation pu

On modest ionization, the change in the photon energies of characteristic K- and L-lines from high-Z (Z ∼ 75 ) ions can be used as an ionization diagnostic (Slabkowska et al., 2014). Indeed, the line shape of the L β 2 line in a spatially resolved

The 670 kA Hawk pulsed power generator at NRL has been configured as a fast (1.2 µs rise time), high inductance (607 nH) driver for a dynamic dense plasma focus (DPF) load in order to create a testbed for the study of charged particle acceleration m

The 650 kA Hawk pulsed power generator at NRL has been configured as a fast (1.2 μs), high in ductance (607 nH) driver for a dense plasma focus load. The current pulse is initiated in a radially injected deuterium plasma. This plasma is accelerated
