“…One of the interesting directions in PF research is experiments with diverse plasmaproducing media. This direction was originally initiated by studies of the possibility of using PF as a driver for magnetic compression of liners [439,440]. The basic idea is that PF is a magnetic energy storage with power amplification in the final stage of discharge (see Section 5.2).…”

“…Later, similar experiments were also carried out with other types of loads. A thin-walled foam liner with a diameter of 10-20 mm [421,440], tungsten wire arrays [440][441][442][443], fine aluminium wires and deuterated polyethylene fibers [441,444], fine-dispersed submicron alumina dust powder [421,440,441,445], and other loads were employed. The possibility of load compression after the current is switched over from a non-cylindrical PCS to different types of loads was demonstrated in experiments carried out at the PF-3 facility.…”

“…Similar results were obtained with wire arrays. It has been shown [440] that, after current sheath contacts with the liner, a major portion of the current continues to flow in the vicinity of the wires during the period necessary for transferring the current to the liner. However, some portion of the current is "dropped" down to the axis, producing a pinch (Figure 118).…”

“…The implementation of this technique seems to be rather promising for producing the target as a dust cloud in the experiments by the liner program [440]. This approach has a number of the advantages related, first of all, with an opportunity to vary-on a wide scale-the mass, configuration and the element composition of such liner.…”

This paper is a sequel to the 1998 review paper “Scientific status of the Dense Plasma Focus” with 16 authors belonging to 16 nations, whose initiative led to the establishment of the International Center for Dense Magnetized Plasmas (ICDMP) in the year 2000. Its focus is on understanding the principal defining characteristic features of the plasma focus in the light of the developments that have taken place in the last 20 years, in terms of new facilities, diagnostics, models, and insights. Although it is too soon to proclaim with certainty what the plasma focus phenomenon is, the results available to date conclusively indicate what it is demonstrably not. The review looks at the experimental data, cross-correlated across multiple diagnostics and multiple devices, to delineate the contours of an emerging narrative that is fascinatingly different from the standard narrative, which has guided the consensus in the plasma focus community for several decades, without invalidating it. It raises a question mark over the Fundamental Premise of Controlled Fusion Research, namely, that any fusion reaction having the character of a beam-target process must necessarily be more inefficient than a thermonuclear process with a confined thermal plasma at a suitably high temperature. Open questions that need attention of researchers are highlighted. A future course of action is suggested that individual plasma focus laboratories could adopt in order to positively influence the future growth of research in this field, to the general benefit of not only the controlled fusion research community but also the world at large.

“…Another constraint in plasma discharges is liners, as shown in Figure 2.5 [original data shown in Fortov et al (2002)]. These highly dense plasma from PF devices acts as a driver for the magnetic compression of liners that can be used for oxygen plasma as well (Fortov et al (2002)).…”

A significantly large scope is available for the scientific and engineering developments of high-throughput ultra-high sensitive oxygen sensors. We give a perspective of oxygen sensing for two physical states of matters—solid-state nanomaterials and plasma. From single-molecule experiments to material selection, we reviewed various aspects of sensing, such as capacitance, photophysics, electron mobility, response time, and a yearly progress. Towards miniaturization, we have highlighted the benefit of lab-on-chip-based devices and showed exemplary measurements of fast real-time oxygen sensing. From the physical–chemistry perspective, plasma holds a strong potential in the application of oxygen sensing. We investigated the current state-of-the-art of electron density, temperature, and design issues of plasma systems. We also show numerical aspects of a low-cost approach towards developing plasma-based oxygen sensor from household candle flame. In this perspective, we give an opinion about a diverse range of scientific insight together, identify the short comings, and open the path for new physical–chemistry device developments of oxygen sensor along with providing a guideline for innovators in oxygen sensing.
