Physics of Solar and Stellar Coronae: G.S. Vaiana Memorial Symposium


Book Description

The original plans for a meeting to celebrate the second centenary of the As tronomical Observatory of Palermo were for a celebration with a double character. The gathering was to have both a historical character, appropriate for a bicenten nial, and a technical character, to note and chronicle the new phase of the history of the Observatory, which has prospered in parallel with the development of this fairly recent topic in astronomical research, the physics of stellar and solar coronae. After the untimely death of the Observatory's Director, Giuseppe S. Vaiana (Pippo to his many friends), a number of colleagues and friends insisted that the celebration should nevertheless be held and should be dedicated to this farsighted scientist who stimulated the development of coronal physics from the early x-ray observations of the solar corona to the recognition of coronae as an observable feature of nearly all stars. This memorial dedication did not change the character of the meeting, which was held in Palermo from 22 to 26 June 1992; as his contributions are very alive in the papers presented at the meeting and collected here, Pippo Vaiana has certainly achieved his place in the history of Astronomy.

Observatories in Earth Orbit and Beyond


Book Description

When I became President of International Astronomical Union Commission 44 for the triennial period 1985-1988, several members of the Organizing Committee and I agreed that it would be a good idea for our Commission to host a conference on observatories in space in view of their increasingly important role in astronomi cal research. IAU Colloquium Number 123 "Observatories in Earth Orbit and Beyond" is the first colloquium sponsored by IAU Com mission 44 on Astronomy from Space, although Commission 44 has co-sponsored numerous colloquia and symposia in the past. The past two decades have seen a flourishing of astronomical observatories in space. Over a dozen orbiting observatories have opened up a new window on the universe, providing hitherto una vailable data in the electromagnetic spectral range from gamma-ray, X-ray, ultraviolet to infrared and radio. This has clearly demon strated the crucial nature of astronomical observations from space. The invited talks of present colloquium consist primarily of reviews of currently operating observatories in space, future observatories that have been approved by sponsoring government or space agencies, the launch systems of U.S.A., E.S.A., U.S.S.R. and Japan, discussions of various orbits and sites (such as the Moon), and alternate approaches in designing space observatories. Several panel discus sions addressed those issues as well as the major unsolved problems of astronomy. Contributed poster papers included descriptions of space observatories that are in planning stage.







Radiation Detection Systems


Book Description

The advances in semiconductor detectors, scintillators, photodetectors such as silicon photomultipliers (SiPM), and readout electronics have experienced tremendous growth in recent years in terms of basic technologies and a variety of applications. The second edition of Radiation Detection Systems presents variety of radiation detection systems, giving readers a broad view of the state-of-the-art in the design of detectors, front-end electronics, and systems offering optimized choices of the detection tools for a particular application. The new edition has been divided into two volumes. This volume on Medical Imaging, Industrial Testing, and Security Applications presents specific applications of the detection systems in medical imaging, industrial testing, and security applications. These newely developed technologies play a vital role in the detection, diagnosis, and treatment of major human diseases. Featuring contributions from leading experts and pioneers in their respective fields, this book: Describes new advances in development of detection systems based on CdZnTe (CZT) and CdTe detectors utilizing a direct conversion of radiation to electric signals Reports a recent progress in technologies and performance of SiPM used for reading the light from scintillators Explores exciting new application opportunities created by development of the cutting-edge detection technologies in X-ray spectroscopy, computed tomography (CT), bone dosimetry, and nuclear medicine (PET, SPECT) Considers the future use of photon-counting detectors in clinical CT scanners providing K-edge imaging to reduce the amount of contrast agents and ultimately offering both an anatomical and a functional information Describes, uses of radiation detection systems in security applications such as luggage scanning, dirty bomb detection, and border control With its combined coverage of new materials and innovative new system approaches, as well as a succinct overview of recent developments, this book is an invaluable tool for any engineer, professional, or student working in electronics or an associated field. Readers can refer to the other volume, Sensor Materials, Systems, Technology, and Characterization Measurements, which puts emphasis on sensor materials, detector structures, front electronics technology, and their designs and system optimization for different applications.
