Download or read book Thermal Design and Thermal Behaviour of Radio Telescopes and their Enclosures written by Albert Greve and published by Springer Science & Business Media. This book was released on 2010-03-17 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio telescopes as well as communication antennas operate under the influence of gravity, temperature and wind. Among those, temperature influences may degrade the performance of a radio telescope through transient changes of the focus, pointing, path length and sensitivity, often in an unpredictable way. Thermal Design and Thermal Behaviour of Radio Telescopes and their Enclosures reviews the design and construction principles of radio telescopes in view of thermal aspects and heat transfer with the variable thermal environment; it explains supporting thermal model calculations and the application and efficiency of thermal protection and temperature control; it presents many measurements illustrating the thermal behaviour of telescopes in the environment of their observatory sites. The book benefits scientists and radio/communication engineers, telescope designers and construction firms as well as telescope operators, observatory staff, but also the observing astronomer who is directly confronted with the thermal behaviour of a telescope.

Download or read book Infrared and Millimeter Waves V9 written by Kenneth J. Button and published by Elsevier. This book was released on 1983-01-01 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared and Millimeter Waves, Volume 9: Millimeter Components and Techniques, Part I compiles the work of several authors while focusing on certain aspects of infrared and millimeter waves, such as sources of radiation, instrumentation, and millimeter systems. This volume deals with millimeter components and techniques. Chapter 1 covers millimeter wave communications, and then the succeeding chapter discusses a comparative study of millimeter waves and transmission lines. This book then tackles dielectric waveguide electrooptic devices, as well as millimeter-wave propagation and remote sensing of the atmosphere, which are covered in Chapter 4. The fifth chapter presents the technology of large radio telescopes for millimeter and submillimeter. The next chapter explains a gyrotron study program, and the last chapter discusses multimode analysis of quasi-optical gyrotrons and gyroklystrons. This book will be of great use for researchers or professionals whose work involves infrared and millimeter waves.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation This collection from the November 2000 workshop reviews the state of the art in observatory site testing methods and instruments across the entire ground-based optical, infrared, and (sub)mm wavelength ranges. The 72 papers investigate the physical mechanisms of atmospheric turbulence, measuring instruments in the visible range, site characterization and atmospheric transparency in the (sub)mm range, tropospheric phase stability, forecasting, site surveys, astroclimatic stations, and phase correction. Specific topics include site monitoring for extremely large telescopes, atmospheric turbulence profiles deduced from solar limb observations, and a comparison of the Pampa La Bola and Llano de Chajnator sites in northern Chile.
