Available in PDF, EPUB and Kindle. Book excerpt: The Texas A and M University plasma focus machine is operational and is beginning to provide good experimental data. It has its origins in several earlier machines and is located in a former service station building with a shield wall that provides a good geometry for neutron measurements. We are operating in the high pressure mode for a plasma focus, similar to previous efforts in the US. Early neutron measurements are providing some insight for the machine's operation.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dense plasma focus (DPF) devices are pulsed power devices capable of producing short-lived, hot and dense plasmas (~1019 cm−3) through a fast compression of plasma sheath. A DPF device provides intense bursts of electrons and ion beams, X-rays, and 2.5 MeV neutrons when operated with deuterium through the fusion reaction 2H(d, n)3He. The Kansas State University DPF machine was designed and constructed in early 2010. The device was characterized to determine its performance as a neutron source. The device was shown to produce 5.0x107 neutrons/pulse using a tungsten-copper anode. Such machines have the advantages of being non-radioactive, movable, and producing short pulses (typically tens of nanoseconds), which allows rapid interrogation. The signature-based radiation-scanning (SBRS) method has been used to distinguish targets that contain explosives or explosive surrogates from targets that contain materials called "inert," meaning they are not explosive-like. Different targets were placed in front of the DPF source at a distance of 45 cm. Four BC-418 plastic scintillators were used to measure the direct neutron yield and the neutrons scattered from various targets; the neutron source and the detectors were shielded with layers of lead, stainless steel, and borated polyethylene to shield against the X-rays and neutrons. One of the plastic scintillators was set at 70° and two were set at 110° from the line of the neutron beam; a bare 3He tube was used for detecting scattered thermal neutrons. Twelve metal cans of one-gallon each containing four explosive surrogates and eight inert materials were used as targets. Nine materials in five-gallon cans including three explosive surrogates were also used. The SBRS method indicated a capability to distinguish the explosive surrogates in both experiments, although the five gallon targets gave more accurate results. The MCNP code was used to validate the experimental work and to simulate real explosives. The simulations indicated the possibility to use the time of flight (TOF) technique in future experimental work, and were able to distinguish all the real explosives from the inert materials.

Available in PDF, EPUB and Kindle. Book excerpt: This book highlights plasma science and technology-related research and development work at institutes and universities networked through Asian African Association for Plasma Training (AAAPT) which was established in 1988. The AAAPT, with 52 member institutes in 24 countries, promotes the initiation and intensification of plasma research and development through cooperation and technology sharing. With 13 chapters on fusion-relevant, laboratory and industrial plasmas for wide range of applications and basic research and a chapter on AAAPT network, it demonstrates how, with collaborations, high-quality, industrially relevant academic and scientific research on fusion, industrial and laboratory plasmas and plasma diagnostics can be successfully pursued in small research labs. These plasma sciences and technologies include pioneering breakthroughs and applications in (i) fusion relevant research in the quest for long-term, clean energy source development using high-temperature, high- density plasmas and (ii) multibillion-dollar, low-temperature, non-equilibrium and thermal industrial plasmas used in processing, synthesis and electronics.

This book was released on 1975 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper shows that an understanding of the nature of the x-ray and neutron producing processes in the plasma focus requires a study of the 'fine structure' of the plasma focus and that this fine structure study requires diagnostic techniques with spacial resolution down to 50 micrometers and time resolution to about 10 ns. Fortunately it has been possible to develop measuring equipment with these high resolutions.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was carried out to determine the relationships between the significant parameters of an unusual pulsed neutron generator. The device employes a novel paraboloidal electrode geometry and belongs to the general class of plasma 'focus' devices in which neutrons are generated by the compression of a dense deuterium plasma. Maximum neutron yields of the order of 10 to the 9th power neutrons/shot were obtained using a bank of six 14-microfarad capacitors at 23 kV for a bank energy of 22 kJ. The parametric variables studied included deuterium gas pressure, bank voltage, anode geometry, and electrode material in the vicinity of the focus. The neutron and x-ray spectra were measured.
