Elements of X-ray Diffraction
Prentice Hall, 2001 - Technology & Engineering - 664 pages
Intended to acquaint the reader with the theory of x-ray diffraction, the experimental methods involved, and the main applications. The book is a collection of principles and methods stressing X-ray diffraction rather than metallurgy. KEY TOPICS: The book is written entirely in terms of the Bragg law and can be read without any knowledge of the reciprocal lattice. It is divided into three main parts--Fundamentals; experimental methods; and applications. MARKET: Designed for beginners, not as a reference tool for the advanced reader.

The filament is heated by a filament current of about 3 amp and emits electrons
which are rapidly drawn to the target by the high voltage across the tube .
Surrounding the filament is a small metal cup maintained at the same high (
negative ) ...
Power Rating All x - ray tubes have a maximum power rating which cannot be
exceeded without injury to the tube . This limit is fixed by the amount of heat that
can be dissipated by the target and is usually stated by the manufacturer in terms
The focal spots of these tubes have areas of less than 1 percent of those of
conventional tubes . ... Pulsed ( or Flash ) Tubes The maximum power at which
an x - ray tube can operate continuously is limited by the rate at which the target
can be ...
