This book was released on 2007 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The X-pinch plasma produces extreme material conditions that make it interesting both as a high-energy-density plasma and an x-ray source for imaging. These extreme conditions include high densities (near solid density, 10 23 ions/CM-3 for Mo), high temperatures (above 2.5 keV for Mo), high energy densities (up to 1012 J/cm 3), high x-ray power densities (up to 1022 W/cm 3), small source sizes (which can be less than 1 mum in diameter), and short time scales for the x-ray radiation (less than 100 ps). These extreme conditions are difficult to produce in a laboratory setting and even harder to study. The X-pinch plasma is produced by driving a high current (100--500 kA, 100 ns FWHM pulse for our experiment) through two or more wires that cross at a point forming an "X." A magnetically driven z-pinch forms near the cross point allowing the X-pinch to reliably reproduce the conditions given above. As such, we present a range of experiments designed to study the conditions produced in the X-pinch plasma. Until recently many of the diagnostics used to study the X-pinch have not had the resolution (spatial or temporal) necessary to determine the actual size or duration of the X-pinch x-ray source. We present experimental results showing the temporal extent of the x-ray radiation produced by an X pinch using an x-ray streak camera with better than 10 ps resolution. We also present experiments designed to study the temporal and spatial relationship of the two different radiation sources (thermal and energetic-electron-generated) observed from an X pinch using a filtered diode array. In addition, we studied the plasma dynamics using both a multi-channel 150 ps, 532 nm (Nd:YAG) laser backlighting system and x-ray radiography (using an X pinch as an x-ray source). We correlate the observed plasma parameters (implosion and explosion rate, neck diameter, axial jet propagation speed, and coronal plasma axial modulation wavelength along the X-pinch legs) to wire material.
Download or read book Magnification Radiography written by A.S. Takahashi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: If the early stages of a disease begin with the involvement of a small area of cells or tissue, the early diagnosis of pathologic changes by means of radio graphy should concentrate first on the detection of such minute changes. The ideal solution would be to produce X-ray images of findings much finer than those observable by the naked eye, and herein lies a new field of research that is believed to be worth developing. The introduction of a 0.3 mm focal-spot rotating-anode tube about 25 years ago opened the way to the clinical application of magnification radiography. Due to the postwar economic situation, we were unable to import this type of X-ray tube, but we believed in the importance of magnification radiography in X-ray diagnosis, and in 1952 we produced an X-ray tube with a 0.15 mm focal spot by reconstructing an existing fixed-anode tube. This X-ray tube has been improved step by step, so that tubes with focal spots of 0.1 mm or 0.05 mm are now available in Japan. Thus it has become possible to obtain 4 to 6 x magnification images of minute lesions that could not be imaged by normal roentgenography.

Download or read book System for Phase contrast X ray Radiography Using X Pinch Radiation and a Method Thereof written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A radiograph system with an anode plate, a cathode plate, and a power source coupled to said anode plate and the cathode plate. At least two wires coupled between the anode plate and the cathode plate provide a configuration to form an X-pinch having a photon source size of less than five microns at energies above 2.5 keV. Material at the configuration forming the X-pinch vaporizes upon application of a suitable current to the wires forming a dense hot plasma and emitting a single x-ray pulse with sufficient photons having energies in the range of from about 2.5 keV to about 20 keV to provide a phase contrast image of an object in the path of the photons. Multiple simultaneous images may be formed of a plurality of objects. Suitable filters and x-ray detectors are provided.

Available in PDF, EPUB and Kindle. Book excerpt: Now fully updated, the second edition of Modern Diagnostic X-Ray Sources: Technology, Manufacturing, Reliability gives an up-to-date summary of X-ray source technology and design for applications in modern diagnostic medical imaging. It lays a sound groundwork for education and advanced training in the physics of X-ray production, X-ray interactions with matter, and imaging modalities and assesses their prospects. The book begins with a comprehensive and easy-to-read historical overview of X-ray tube and generator development, including key achievements leading up to the current technological and economic state of the field. The book covers the physics of X-ray generation, including the process of constructing X-ray source devices. The stand-alone chapters can be read in order or in selections. They take you inside diagnostic X-ray tubes, illustrating their design, functions, metrics for validation, and interfaces. The detailed descriptions enable objective comparison and benchmarking. This detailed presentation of X-ray tube creation and functions enables you to understand how to optimize tube efficiency, particularly with consideration for economics and environmental care. It also simplifies faultfinding. Along with covering the past and current state of the field, the book assesses the future regarding developing new X-ray sources that can enhance performance and yield greater benefits to the scientific community and to the public. After heading international R&D, marketing and advanced development for X-ray sources with Philips, and working in the X-ray industry for more than four decades, Rolf Behling retired in 2020 and is now the owner of the consulting firm XtraininX, Germany. He holds numerous patents and is continuously publishing, consulting and training.

Available in PDF, EPUB and Kindle. Book excerpt: As part of its current physics decadal survey, Physics 2010, the NRC was asked by the DOE, NSF, and NASA to carry out an assessment of and outlook for the broad field of plasma science and engineering over the next several years. The study was to focus on progress in plasma research, identify the most compelling new scientific opportunities, evaluate prospects for broader application of plasmas, and offer guidance to realize these opportunities. The study paid particular attention to these last two points. This "demand-side" perspective provided a clear look at what plasma research can do to help achieve national goals of fusion energy, economic competitiveness, and nuclear weapons stockpile stewardship. The report provides an examination of the broad themes that frame plasma research: low-temperature plasma science and engineering; plasma physics at high energy density; plasma science of magnetic fusion; space and astrophysical science; and basic plasma science. Within those themes, the report offers a bold vision for future developments in plasma science.
