In the four years since the first Trieste Meeting on Spin and Polarization Dynamics in Nuclear and Particle Physics, considerable progress has been made both in the theoretical and experimental aspects of this field. The polarization phenomena have given rise to many more detailed and crucial tests which enhance our understanding of particle physics. New information can also be uncovered in the process of conducting the various tests. For this reason, considerable efforts have been put into the present and future accelerators to extend the experimental data to measure polarization asymmetries for both polarized targets and polarized scattered and produced particles. The 2nd Adriatico Research Conference held in January 1992 brought together both theorists and experimentalists who presented many new findings. These findings have been compiled into this compact volume to give a complete picture of the wide range of theoretical and experimental problems, difficulties, results, prospects and hopes which are at the core of particle physics studies today. It will be a useful guide for the present status of polarization phenomena and their fundamental implications.

The proceedings presents articles exploring the wide range of physics with can be addressed with measurements using both polarized beams and polarized targets. The conference concentrated on the physics to be done using polarized beams on polarized targets and include selected highlights on advances in the technology. Topics covered include studies of nuclear structure and few-body reactions to test fundamental symmetries, measurements of electromagnetic form factors and of the internal spin structure of nucleons, and tests of QCD.

The 9th International Symposium on High Energy Spin Physics was held in Bonn, 6-15 September 1990, with the Physikalisches Institut der Universitat Bonn as the host. The symposium was preceded by a series of four workshops on • polarized electron sources and electron spin polarimeters • Siberian snakes and polarization in circular machines • polarized gas targets • polarized solid targets. 160 participants from 11 countries, among them many young physicists, came together and discussed mainly technological spin problems. The high level of participation indicates that workshops combined with the symposium are attractive not only for people who plan and prepare polarized beams and targets but also for experimentalists and theorists dealing with high energy spin physics. At these workshops many very interesting and important recent results were presented and reviewed. Thus we hope these proceedings will be valuable to many researchers in these fields. The Organizing Committee would like to thank all participants, in particular the speakers and the session chairmen, for their contributions to the workshops and for helping to create a lively and stimulating atmosphere. Special thanks go to the organizers - W. Haeberli, S. Mango, E. Reichert, E. Steffens, W. Thiel, U. Wienands - for their cooperation in preparing and running these workshops. We gratefully acknowledge the enthusiastic help of the members of our institute in preparing and running the conference and the workshops, especially Mrs. D. FaSbender, Mrs. E. Wendorf, Mrs. J. Wetzel, and Dr. U.Idschok.

Polarization Measurement and Control in Optical Fiber Communication and Sensor Systems A practical handbook covering polarization measurement and control in optical communication and sensor systems In Polarization Measurement and Control in Optical Fiber Communication and Sensor Systems, the authors deliver a comprehensive exploration of polarization related phenomena, as well as the methodologies, techniques, and devices used to eliminate, mitigate, or compensate for polarization related problems and impairments.

This Open Access book is drawn from lectures dispensed at the U.S. Particle Accelerator School (USPAS) Summer 2021 Spin Class, by experts in the field. It is an introduction to the dynamics of spin in charged particle accelerators, and to the accelerator components and spin manipulation techniques, including helical snakes and spin rotators, which enable and allow preserving beam polarization. It is aimed at graduate students or upper division undergraduate students with an interest in this multi-disciplinary field, which includes the future electron-ion collider at the Brookhaven National Laboratory, high energy lepton and proton collider projects, and other electric dipole moment search storage rings. It is also aimed at physicists or engineers working in accelerator-related fields who wish to familiarize themselves with spin dynamics and polarized beam concepts, tools, components, and purposes. This is an open access book.
