Detectors and Sources for THz and IR by Fedir F. Sizov Pdf

IR and THz technologies are widely used in security screening and surveillance, astronomy, spectroscopy, biomedicine, food and package inspection, detection of concealed weapons, vision through camouflage, etc. There are increasing demands for the fast transmission of large amounts of data. THz radiation penetrates dielectric materials like plastics, ceramics or cardboard allowing contact-free testing. Medical imaging technologies can provide guidance for surgeons in delimiting the margins of tumors, help clinicians to visualize diseased areas, etc. Keywords: THz and IR Detectors, THz and IR Sources, Superconducting Photon Detectors, Superconducting THz Detectors, Graphene-based Detectors, THz Sensors with Metamaterials, Photoconductive Antenna Detectors, Imaging, Communication, Spectroscopy, Sensing, Security Screening, Surveillance, Astronomy, Biomedicine, Food Inspection, Package Inspection, Concealed Weapons Detection, Transmission of Large Amounts of Data, Non-destructive Testing, Contact-free Testing, Medical Imaging Technologies.

Development of Coherent Detector Technologies for Sub-Millimetre Wave Astronomy Observations by Boon Kok Tan Pdf

The thesis describes the development of receiver technologies for sub-millimetre astronomy instruments, focusing on high performance coherent cryogenic detectors operating close to the superconductor gap frequency. The mixer chip which comprises the SIS devices, fed by a unilateral finline and matching planar circuits was fabricated on 15 micron silicon substrate using the recently developed Silicon-On-Insulator (SOI) technology. This offered broadband IF and RF performance, with fully integrated on-chip planar circuits resulting in an easily reproducible mixer chip and a simple mixer block. An important consequence of this design is that it can be extended to the supra-THz region and making the fabrication of multi-pixel heterodyne arrays feasible. The extension of the operation of major telescopes such as ALMA, APEX and the GLT from single pixel to large format arrays is the subject of extensive research at present time since it will allow fast mapping combined with high resolution of the submillimetre sky. The technology described in this thesis makes a major contribution to this effort.

Inventing a Space Mission by Vincent Minier,Roger-Maurice Bonnet,Vincent Bontems,Thijs de Graauw,Matt Griffin,Frank Helmich,Göran Pilbratt,Sergio Volonte Pdf

This book describes prominent technological achievements within a very successful space science mission: the Herschel space observatory. Focusing on the various processes of innovation it offers an analysis and discussion of the social, technological and scientific context of the mission that paved the way to its development. It addresses the key question raised by these processes in our modern society, i.e.: how knowledge management of innovation set the conditions for inventing the future? In that respect the book is based on a transdisciplinary analysis of the programmatic complexity of Herschel, with inputs from space scientists, managers, philosophers, and engineers. This book is addressed to decision makers, not only in space science, but also in other industries and sciences using or building large machines. It is also addressed to space engineers and scientists as well as students in science and management.

Radio, Submillimeter, and X-Ray Telescopes by N. G. Basov Pdf

This volume contains the results of research and development connected with the creation oftelescopes intended for the new regions of the spectrum mastered by astronomy: the x-ray, submillimeter (far infrared), and radio regions. The creation of x-ray, submillimeter, and radio telescopes and the receiver apparatus connected with them is a complicated and, in many respects, unusual problem. Therefore, the experience accumulated at the Institute of Physics can prove useful to specialists working in this field, This volume is intended for scientists, engineers, and builders occupied in research and development in the fields of x-ray, submillimeter, and radio astronomy as well as for students of advanced courses in these specialties, V CONTENTS A Reflecting X-Ray Telescope for an Orbital Astrophysical Station. • • • • • • • • • 1 I.

Josephson Junctions by Edward L. Wolf,Gerald B. Arnold,Michael A. Gurvitch,John F. Zasadzinski Pdf

This book summarizes the history and present status and applications of Josephson junctions. These devices are leading elements in superconducting electronics and provide state-of-the-art performance in detection of small magnetic fields and currents, in several digital computing methods, and in medical diagnostic devices and now provide voltage standards used worldwide. Astronomical infrared (IR) telescopes, including the South Pole Telescope, use these junctions in combinations called superconducting quantum interference devices (SQUIDs).
