Book Synopsis Advanced Interferometers and the Search for Gravitational Waves by : Massimo Bassan
Download or read book Advanced Interferometers and the Search for Gravitational Waves written by Massimo Bassan and published by Springer. This book was released on 2014-07-08 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for gravitational radiation with optical interferometers is gaining momentum worldwide. Beside the VIRGO and GEO gravitational wave observatories in Europe and the two LIGOs in the United States, which have operated successfully during the past decade, further observatories are being completed (KAGRA in Japan) or planned (ILIGO in India). The sensitivity of the current observatories, although spectacular, has not allowed direct discovery of gravitational waves. The advanced detectors (Advanced LIGO and Advanced Virgo) at present in the development phase will improve sensitivity by a factor of 10, probing the universe up to 200 Mpc for signal from inspiraling binary compact stars. This book covers all experimental aspects of the search for gravitational radiation with optical interferometers. Every facet of the technological development underlying the evolution of advanced interferometers is thoroughly described, from configuration to optics and coatings and from thermal compensation to suspensions and controls. All key ingredients of an advanced detector are covered, including the solutions implemented in first-generation detectors, their limitations, and how to overcome them. Each issue is addressed with special reference to the solution adopted for Advanced VIRGO but constant attention is also paid to other strategies, in particular those chosen for Advanced LIGO.
Book Synopsis Fundamentals Of Interferometric Gravitational Wave Detectors (Second Edition) by : Peter R Saulson

This book was released on 2017-02-16 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The content of the Saulson’s book remains valid and offers a versatile introduction to gravitational wave astronomy. The book is appropriate for undergraduate students and can be read by graduate students and researchers who want to be involved in either the theoretical or the experimental traits of the study of gravitational waves.'Contemporary PhysicsLIGO's recent discovery of gravitational waves was headline news around the world. Many people will want to understand more about what a gravitational wave is, how LIGO works, and how LIGO functions as a detector of gravitational waves.This book aims to communicate the basic logic of interferometric gravitational wave detectors to students who are new to the field. It assumes that the reader has a basic knowledge of physics, but no special familiarity with gravitational waves, with general relativity, or with the special techniques of experimental physics. All of the necessary ideas are developed in the book.The first edition was published in 1994. Since the book is aimed at explaining the physical ideas behind the design of LIGO, it stands the test of time. For the second edition, an Epilogue has been added; it brings the treatment of technical details up to date, and provides references that would allow a student to become proficient with today's designs.
Book Synopsis Aspects, Techniques and Design of Advanced Interferometric Gravitational Wave Detectors by : Pablo Jose Barriga Campino
Download or read book Aspects, Techniques and Design of Advanced Interferometric Gravitational Wave Detectors written by Pablo Jose Barriga Campino and published by . This book was released on 2009 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research described in this thesis investigates some of the key technologies required to improve the sensitivity of the next generation of interferometric gravitational wave detectors. A complete optical design of a high optical power, suspended mode-cleaner was undertaken in order to reduce any spatial or frequency instability of the input laser beam. This includes a study of thermal effects due to high circulating power, and a separate study of a vibration isolation system. In the last few years the Australian Consortium for Interferometric Gravitational Astronomy (ACIGA) has developed an advanced vibration isolation system, which is planned for use in the Australian International Gravitational Observatory (AIGO). A local control system originally developed for the mode-cleaner vibration isolator has evolved for application to the main vibration isolation system. Two vibration isolator systems have been assembled and installed at the Gingin Test Facility ( 80km north of Perth in Western Australia) for performance testing, requiring installation of a Nd:YAG laser to measure the cavity longitudinal residual motion. Results demonstrate residual motion at nanometre level at 1 Hz. Increasing the circulating power in the main arm cavities of the interferometer can amplify the photon-phonon interaction between the test mass and the circulating beam, enhancing the three-mode parametric interaction and creating an optical spring effect. As part of a broader study of parametric instabilities, in collaboration with the California Institute of Technology, a simulation of the circulating beam in the main arms of Advanced LIGO was completed to determine the characteristics of the higher order optical modes. The simulation encompassed di raction losses, optical gain, optical mode Q-factor and mode frequency separation. The results are presented for varying mode orders as a function of mirror diameter. The effect of test mass tilt on diffraction losses, and different coatings conffgurations are also presented. These simulations led to a study of the effect of power recycling cavities in higher order mode suppression. Current interferometric gravitational wave detectors in operation have marginally stable recycling cavities, where higher order modes are enhanced by the power recycling cavity, effectively increasing the parametric gain. A study of stable recycling cavities was undertaken in collaboration with the University of Florida, which has evolved into a proposed design for a 5 kilometre AIGO interferometer. This thesis concludes with an analysis of the work here presented and an outline of future work that will help to improve the design of advanced interferometric gravitational wave detectors.
Book Synopsis Control of the Gravitational Wave Interferometric Detector Advanced Virgo by : Julia Casanueva Diaz
Download or read book Control of the Gravitational Wave Interferometric Detector Advanced Virgo written by Julia Casanueva Diaz and published by Springer. This book was released on 2018-07-28 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the development and implementation of the longitudinal, angular and frequency controls of the Advanced Virgo detector, both from the simulation and experimental point of view, which contributed to Virgo reaching a sensitivity that enabled it to join the LIGO-Virgo O2 run in August 2017. This data taking was very successful, with the first direct detection of a binary black hole merger (GW170814) using the full network of three interferometers, and the first detection and localization of a binary neutron star merger (GW170817). The second generation of gravitational wave detector, Advanced Virgo, is capable of detecting differential displacements of the order of 10–21m. This means that it is highly sensitive to any disturbance, including the seismic movement of the Earth. For this reason an active control is necessary to keep the detector in place with sufficient accuracy.
Book Synopsis Compensation of Strong Thermal Lensing in Advanced Interferometric Gravitational Waves Detectors by : Jérôme Degallaix
Download or read book Compensation of Strong Thermal Lensing in Advanced Interferometric Gravitational Waves Detectors written by Jérôme Degallaix and published by . This book was released on 2006 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: A network of laser interferometer gravitational waves detectors spread across the globe is currently running and steadily improving. After complex data analysis from the output signal of the present detectors, astrophysical results begin to emerge with upper limits on gravitational wave sources. So far, however no direct detection has been announced. To increase the sensitivity of current detectors, a second generation of interferometers is planned which will make gravitational wave astronomy a reality within one decade. The advanced generation of interferometers will represent a substantial upgrade from current detectors. Especially, very high optical power will circulate in the arm cavities in order to reduce by one order of magnitude the shot noise limited sensitivity in high frequency. However, the theoretical shot noise limit will only be achieved after implementation of complex thermal lensing compensation schemes. Thermal lensing is direct consequence of the residual optical absorption inside the substrate and coating of the test masses and could have tragic consequences for the functionality of the interferometer. The Australian Consortium for Interferometric Gravitational Astronomy (ACIGA) in collaboration with LIGO will run a series of high optical power tests to understand the characteristics and effects of thermal lensing. During these tests, techniques to compensate thermal lensing will be experimented. This thesis mainly focused on the first high optical power test in Gingin, Australia. The first test will consist of a Fabry Perot cavity with the sapphire substrate of the input mirror inside the cavity. Due to the high optical circulating power a strong convergent thermal lens will appear in the input mirror substrate. Because of the presence of the thermal lens inside the cavity, the size of the cavity waist will be reduced and the cavity circulating power will decrease. Simulations using higher order mode expansion and FFT propagation code were completed to estimate ways to compensate strong thermal lensing for the Gingin first test. The term strong thermal lensing is used because the thermal lens focal length is comparable to the design focal length of the optical components. The expected performance of a fused silica compensation plate is presented and advantages and limits of this method are discussed. Experimental results on small scale actuators which can potentially compensate thermal lensing are detailed. The knowledge gained from these experiments was valuable to design the real scale compensation plate which was used in the first Gingin test. This test was carried at the end of 2005. The thermal lens due to 1 kW of optical power circulating in the sapphire substrate was successfully compensated using a fused silica plate. Yet, thermal lensing compensation may only be required for room temperature advanced interferometer. Indeed, we showed that cooling the interferometer mirror to cryogenic temperature can eliminate the thermal lensing problem and also substantially decrease the mirror thermal noise.

Book Synopsis Quantum Enhancement of a 4 km Laser Interferometer Gravitational-Wave Detector by : Sheon S. Y. Chua
Download or read book Quantum Enhancement of a 4 km Laser Interferometer Gravitational-Wave Detector written by Sheon S. Y. Chua and published by Springer. This book was released on 2015-05-09 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work in this thesis was a part of the experiment of squeezed light injection into the LIGO interferometer. The work first discusses the detailed design of the squeezed light source which would be used for the experiment. The specific design is the doubly-resonant, traveling-wave bow-tie cavity squeezed light source with a new modified coherent sideband locking technique. The thesis describes the properties affecting the squeezing magnitudes and offers solutions which improve the gain. The first part also includes the detailed modeling of the back-scattering noise of a traveling Optical Parametric Oscillator (OPO). In the second part, the thesis discusses the LIGO Squeezed Light Injection Experiment, undertaken to test squeezed light injection into a 4km interferometric gravitational wave detector. The results show the first ever measurement of squeezing enhancement in a full-scale suspended gravitational wave interferometer with Fabry-Perot arms. Further, it showed that the presence of a squeezed-light source added no additional noise in the low frequency band. The result was the best sensitivity achieved by any gravitational wave detector. The thesis is very well organized with the adequate theoretical background including basics of Quantum Optics, Quantum noise pertaining to gravitational wave detectors in various configurations, along with extensive referencing necessary for the experimental set-up. For any non-experimental scientist, this introduction is a very useful and enjoyable reading. The author is the winner of the 2013 GWIC Theses Prize.

Download or read book High-power Operation of Interferometric Gravitational-wave Detectors written by Aaron Buikema and published by . This book was released on 2020 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the conclusion of the first two observing runs of the Advanced LIGO detectors, which saw the first direct detection of gravitational waves, we are firmly in the era of gravitational-wave astronomy. To reach the highest sensitivities, current interferometric gravitational-wave detectors are designed for hundreds of kilowatts of circulating optical power. At these high circulating powers, the sensitivity of the detectors to gravitational waves will be limited by the quantum properties of the light: shot noise at frequencies above ~ 100 Hz, and quantum radiation pressure noise at lower frequencies. To reach the high powers necessary for achieving the quantum noise limits imposed by the light, it is essential to solve the control problems and understand the additional noise introduced by high power operation. Additionally, development of high-power laser sources that reach the stringent noise and reliability requirements is crucial. This work comprises three experiments aimed at reaching the radiation-pressure-dominated regime of interferometric gravitational-wave detectors. The first part presents results from a high-power, meter-long Fabry-Prot Michelson interferometer to probe classical and quantum radiation pressure effects using a gram-scale mechanical oscillator. The second part is an exploration of the effects of electric fields and charging of test masses on the sensitivity of the LIGO detectors, which may limit the ability to observe radiation-pressure effects. Finally, we describe the development and characterization of a high-power, narrow-linewidth ytterbium-doped fiber amplifier for use in future gravitational-wave detectors.
