Designed for physics students treating the underlying basis for modern techniques and the devices used, this timely survey describes current experimental methods in a clear and accessible text. This up-to-date volume provides an essential part of undergraduate physics training; until now, students were often expected to learn many of these methods in the laboratory without proper introduction. The broad coverage of available techniques includes discussion of state-of-the-art electronic equipment, as well as such topics as discrete semiconductor devices, signal processing, thermometry, optical components, nuclear instrumentation, and x-ray diffraction methods. Professor Dunlap's text will serve not only as a complete introduction for majors but also as a reference work for technicians throughout a professional career. In addition to tutorial discussions presented, tables of numerical data and constants are included, further enhancing the book as a permanent reference.
