چکیده

We report on a substantial increase in the acceleration potential achieved with a LiTaO3 pyroelectric crystal. With a single 2.5 cm diameter and 2.5 cm long z-cut crystal without electric field-enhancing nanotip we produced positive ion beams with maximal energies between 300 and 310 keV during the cooling phase when the crystal was exposed to 5 mTorr of deuterium gas. These values are about a factor of 2 larger than previously obtained with single pyroelectric crystals. © 2010 American Institute of Physics. doi:10.1063/1.3309841

Applications of pyroelectric particle accelerators

The discovery of pyroelectric X-ray generation in 1992 by Brownridge has led to a recent surge of interest in the use of the pyroelectric effect as a means of producing useful radiation. By heating or cooling a pyroelectric crystal such as lithium tantalate (LiTaO3) in a vacuum, a potential on the order of 100 kV can be generated. This potential is great enough to eject electrons from the cryst...

Electron and positive ion acceleration with pyroelectric crystals

The phenomenon of pyroelectric electron emission has been employed to develop miniature x-ray sources, such as the Cool-X by Amptek swww.amptek.com/coolx.htmld. The source strength of a pyroelectric x-ray generator is dependent on the emitted electron energy and current. Similarly, the source strength of a pyroelectric neutron generator will be dependent on the energy and production rate of deu...

Electron Acceleration for X-ray Production Using Paired Pyroelectric Crystals

The exposure of pyroelectric crystals to a heating cycle in near-vacuum conditions has been shown to be a viable method of producing x-rays. The z-negative face of the crystal forms a positive charge as the crystal heats, and a negative charge as it cools. The opposite is true for the z-positive face. Literature has shown that this charge is great enough to accelerate electrons to energies of u...
