Particle Detection with Drift Chambers [Paperback]

This second edition is a thoroughly revised, updated and expanded version of a classic text, with lots of new material on electronic signal creation, amplification and shaping. Its still a thorough general introduction, too, to the theory and operation of drift chambers. The topics discussed include the basics of gas ionization, electronic drift and signal creation and discuss in depth the fundamental limits of accuracy and the issue of particle identification.

A drift chamber is an apparatus for measuring the space coordinates of the trajectory of a charged particle. This is achieved by detecting the ionization electrons produced by the charged particle in the gas of the chamber and by measuring their drift times and arrival positions on sensitive electrodes. When the multiwire proportional chamber, or Charpak chamber as we used to call it, was introduced in 1968, its authors had already noted that the time of a signal could be useful for a coordinate determination, and rst studies with a drift ch- ber were made by Bressani, Charpak, Rahm and Zupanci c in 1969. When the rst operational drift-chamber system with electric circuitry and readout was built by Walenta, Heintze and Schurlein ? in 1971, a new instrument for particle experiments had appeared. A broad study of the behaviour of drifting electrons in gases began in laboratories where there was interest in the detection of particles.Gas Ionization by Charged Particles and by Laser Rays.- The Drift of Electrons and Ions in Gases.- Electrostatics of Tubes, Wire Grids and Field Cages.- Amplification of Ionization.- Creation of the Signal.- Electronics for Drift Chambers.- Coordinate Measurement and Fundamental Limits of Accuracy.- Geometrical Track Parameters and their Errors.- Ion Gates.- Particle Identification by Measurement of Ionization.- Existing Drift Chambers #x2013; An Overview.- Drift-Chamber Gases.
