Experimental geometry for bremsstrahlung energy measurements for a paired-crystal system. (A cooling phase is depicted.)
Experimental geometry for the direct measurement of electron emission from a single-crystal pyroelectric source.
Spectrum showing that the electrons emitted from a single-crystal pyroelectric crystal at a given time are nearly monoenergetic and can have an energy of .
X-ray spectrum showing the bremsstrahlung and characteristic x-ray production from a paired-crystal pyroelectric source. The endpoint energy shows that the maximum electron energy from a paired-crystal system must be at least .
Experimental geometry for the detection of positive ions accelerated by the potential from a pyroelectric crystal.
Positive-ion spectra for a lithium tantalate driven source during cooling. The positive-ion peak changes in energy as the crystal cools.
Positive-ion spectra for a lithium niobate driven source during cooling. The peak which changes in energy is caused by positive ions, while the peak that stays stationary is due to characteristic x-ray emission from the electrons striking the crystal.
Spectrum showing pileup peaks for electrons emitted by a crystal.
Comparison of observed pileup peak area to calculated pileup expected from a random emission source.
