ABSTRACT
The electric dipole moment in the pyroelectric crystal changes by heating or cooling the pyroelectric crystal. The surface of the pyroelectric crystal becomes electrically charged when its temperature is changed. This chapter describes a method to assemble a pyroelectric X-ray tube and details on X-rays generated using the pyroelectric X-ray tube. The pyroelectric X-ray tube will be portable by inserting a valve between the vacuum flange and vacuum pump and then detaching the vacuum pump from the valve once the pressure is sufficient to generate X-rays. The chapter demonstrates the application of the pyroelectric electron probe microanalysis (EPMA) to elemental analysis of particles with a size of several hundred micrometers. It examines pyroelectric cathodoluminescence spectrometer which analyzes visible light emitted from a sample as the result of electron bombardment. The chapter explains a method to focus the electric field in the pyroelectric EPMA.
