“…The properties of matter on all scales (atoms, molecules, condensed matter, plasmas) are severely modified when exposed to strong magnetic fields (B-fields) [1]. The possibility of imposing a strong, laser-driven B-field to a variety of samples opens interesting perspectives for laboratory studies of magnetized plasma- [2], atomic- [3] and nuclear-physics [4]. We foresee great progress on the understanding of systems of astrophysical scale [5][6][7][8][9][10], on the improvement of inertial fusion energy schemes [11][12][13][14] and for various applications of magneticallyguided particle beams [15,16], among many other applications.…”

Quasi-static magnetic-fields up to 800 T are generated in the interaction of intense laser pulses (500 J, 1 ns, − 10 W cm 17 2 ) with capacitor-coil targets of different materials. The reproducible magnetic-field peak and rise-time, consistent with the laser pulse duration, were accurately inferred from measurements with GHz-bandwidth inductor pickup coils (B-dot probes). Results from Faraday rotation of polarized optical laser light and deflectometry of energetic proton beams are consistent with the B-dot probe measurements at the early stages of the target charging, up to ≈ t 0.35 ns, and then are disturbed by radiation and plasma effects. The field has a dipole-like distribution over a characteristic volume of 1 mm 3 , which is consistent with theoretical expectations. These results demonstrate a very efficient conversion of the laser energy into magnetic fields, thus establishing a robust laser-driven platform for reproducible, well characterized, generation of quasi-static magnetic fields at the kT-level, as well as for magnetization and accurate probing of high-energy-density samples driven by secondary powerful laser or particle beams.

A power generating fusion reactor will operate under extreme conditions of temperature and high-energy particle fluences. The energy is produced by the nuclear fusion reaction of deuterium and tritium in a plasma, which can reach temperatures of the order of 100 million C. The reaction generates helium, high energy (14 MeV) neutrons and gamma rays. The operation of a fusion reactor requires diagnostic equipment for the monitoring of temperature, pressure, magnetic fields, radiation energy and fluence, and other operational parameters. Functional materials, in particular ferroelectrics, can play many useful roles in these types of measurement. Many ferroelectrics are also known for their radiation hardness, which may favour their use in this environment. This review paper describes the functions where ferroelectrics may find useful application in a reactor, the effects of the reactor environment on materials in general, and the effects on ferroelectrics in particular. Though this review is centered on the technology associated with the Joint European Torus (JET), International Thermo-Nuclear Reactor (ITER) and the future planned DEMOnstration Power Plant (DEMO) fusion reactor types there are some similar materials related issues associated with the many other systems being explored worldwide. Conclusions are then made about the future for ferroelectric materials in fusion reactors and some of the research challenges that need to be addressed.

“…Judging by the experience of the two DPF devices (NX2 at Singapore [11] and FF1 at Lawrenceville [12], USA) which have reported significantly higher neutron yield than devices of comparable energy by operating at higher than 10 mbar deuterium pressure, and numerical simulations with the Lee model at 60 torr [13] which also show increased neutron yield, one could expect orders of magnitude improvement in the yield of fusion neutrons (or other binary reactions) if efficient DPF operation could be achieved at deuterium pressures of 0.1-1 bar. This paper explores the design parameter space for such HPO-DPF operating with deuterium using the revised Resistive Gratton-Vargas (RGV) model [10,14,15] with a view to identify a practicable set of system parameters and their scaling.…”

The potential of the Dense Plasma Focus (DPF) for industrial applications in many fields is well recognized, although yet to be realized in practice. Particularly attractive is the possibility of its use as inexpensive industrial source of nuclear reactions for diverse high value applications such as fast pulsed neutron radiography of hydrogenous materials, non-intrusive neutron interrogation of concealed organic contraband and rapid production of short lived radioisotopes for medical diagnostics and therapy.Recently, it has been suggested that it may be possible to operate the DPF efficiently in a High-Pressure-Optimized (HPO) mode. This paper explores the design parameter space for such HPO-DPF based on the revised Resistive Gratton-Vargas (RGV) model with a view to identify a practicable set of system parameters and their scaling. The current waveform predicted by the revised RGV model for the chosen set of parameters is fitted to the Lee model to estimate the likely neutron yield.
