This book was released on with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book we investigate the physics and technology of modern superconducting detectors in view of their employment in millimetre and submillimetre receivers that require high performance such as astronomical telescopes. The book presents an in-depth description of the physics of these detectors and also how they can be designed and integrated in the receiver, in the frequency range from 100 GHz to 1.5 THz. Our discussion covers the device physics and the detector chip design that couples the signal to the detector. Both coherent detection using superconducting mixers and total power detection using bolometers are covered.

This book was released on 2015-09-15 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Josephson junctions are highly nonlinear and respond up to infrared frequencies. A wide variety of high frequency applications have been explored. In addition, several high frequency superconducting devices are being developed which do not use the Josephson effect. These include a superconducting version of the Schottky barrier diode for use as a heterodyne mixer and a video detector, and also a composite superconducting bolometer. In this review, the state of development of superconducting mixers, detectors, and parametric amplifiers at microwave, millimeter, and submillimeter wavelengths is discussed. Emphasis will be placed on developments which have taken place since 1974 when a previous review was circulated.

Download or read book Detection of Light written by G. H. Rieke and published by Cambridge University Press. This book was released on 1996-06-27 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: How does a quantum well detector, a silicon BIB or a CCD work? How are heterodyne techniques used in infrared detectors and submillimeter receivers? And how do you specify the performance of any detector system? This volume answers all these questions with an up-to-date review of all the techniques for the detection of radiation. This presentation approaches detectors from the perspective of the underlying physics; and in this way it provides a unified understanding of the detection of radiation in the ultraviolet through to the submillimetre. Clearly worked examples demonstrate the physics involved and problems are provided to increase the reader's knowledge of how each system works. This clearly written and authoritative review of modern detector systems will develop the understanding of final year undergraduate and graduate students, and will provide a valuable reference for professionals in astronomy, engineering and physics.

This book was released on 2020-10-09 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis studies the development of LEKID arrays for the use in a mm-wave camera for the IRAM 30m telescope. This includes the design and fabrication of the superconducting microresonators, the modeling and optimization of the mm-wave coupling to the detector and the characterization of the arrays at low temperatures. The results obtained brought IRAM to test a prototype instrument at the telescope, where first astronomical results have been achieved, which are also presented in this work.

This book was released on 2010-03-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings are broadly of interest to many research areas which utilize low temperature detectors for measurements. These include photon sciences at synchrotron radiation facilities, neutrino physics, nuclear physics, atomic physics, dark matter searches, sub-Kelvin cryogenic refrigeration systems, novel detectors or astrophysics from millimeter wave bolometers, to single photon energy and time resolving from near-infrared to ultraviolet optical detectors, through the highest spectral resolution x-ray and gamma ray detectors, to large mass detectors for dark matter searches. These applications include particle phyisics, astrophysics, materials physics, and security non-proliferation, and cryogenic engineering. This thoroughly peer-reviewed proceedings of the Thirteenth International Workshop on Low Temperature Detectors provides a snapshot of the state-of-the-art in low temperature particle and radiation detectors. In 173 original research papers from 233 distinct presentations, the physics and applications of this extremely high performance type of detectors is described in detail, including their application to such diverse fields as astrophysics at all wavelengths from the submillimeter to gamma-ray, dark matter searches, neutrino astrophysics, atomic physics, nuclear physics, biophysics, and materials science.

Available in PDF, EPUB and Kindle. Book excerpt: The series of projects described in this dissertation was stimulated by the discovery of high temperature superconductivity. Our goal was to develop useful applications which would be competitive with the current state of technology. The high-[Tc] microbolometer was developed into the most sensitive direct detector of millimeter waves, when operated at liquid nitrogen temperatures. The thermal boundary resistance of thin YBa[sub 2]Cu[sub 3]0[sub 7-[delta]] films was subsequently measured and provided direct evidence for the bolometric response of high-[Tc] films to fast (ns) laser pulses. The low-[Tc] microbolometer was developed and used to make the first direct measurements of the frequency dependent optical efficiency of planar lithographed antennas. The hot-electron microbolometer was invented less than a year prior to the writing of this dissertation. Our analysis, presented here, indicates that it should be possible to attain up to two orders of magnitude higher sensitivity than that of the best available direct detectors when operated at the same temperature. The temperature readout scheme for this device could also be used to measure the intrinsic interaction between electrons and phonons in a metal with a sensitivity that is five orders of magnitude better than in previous measurements. Preliminary measurements of quasiparticle trapping effects at the interface between a metal and a superconductor are also presented.
