This book treats the experimental techniques and instrumentation most often used in nuclear and particle physics experiments as well as in various other experiments. It provides useful results and formulae, technical know-how and informative details. This second edition has been revised; sections on Cherenkov radiation and radiation protection have been updated and extended. Thanks to the author's long teaching experience, the material is presented in a very practical, hands-on way making the book a useful text and laboratory companion for students and experienced scientists alike.
