چکیده

Pyroelectric crystals have been used to achieve D-D fusion. One goal of research conducted at RPI is to develop a portable neutron generator using pyroelectric crystals as an ionization and acceleration source for deuterium ions. The research reported here includes the use of two pyroelectric crystals to generate neutrons in a portable prototype vacuum system. Experiments were conducted to determine an optimal deuterium gas operating pressure for neutron production experiments. A lithium tantalate crystal (LiTaO3) with a tip was used to ionize D2 gas and accelerate deuterium ions into a deuterated polyethylene target mounted on a second crystal. The crystals were mounted in a small vacuum chamber with two isolation valves that allow the system to be closed after it has been pumped down and filled with D2 gas.

Pyroelectric crystal D-D and D-T neutron generators

Pyroelectric neutron generators are a recent development utilizing the pyroelectric effect to produce an accelerating electric field and thus enabling creation of small electron and ion accelerators without external high voltage power supply. The principle of operation includes a pyroelectric crystal (LiTaO3 for example) placed in vacuum and simple heating (or cooling) of the crystal to cause a...

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...

Development of a Palm-size Electron Probe X-ray Analyzer

An electron probe microanalyzer (EPMA) with a palm-size chamber including the electron source and the sample stage was developed using a pyroelectric crystal. Energy of obtained continuous X-rays and lower limits of detection of transition metals (titanium, iron, and nickel) were evaluated. End point energy (Duane-Hunt limit) of obtained continuous X-rays was about 40 keV, but the palm-size EPM...

Liquid micro-lens array activated by selective electrowetting on lithium niobate substrates.

Lens effect was obtained in an open microfluidic system by using a thin layer of liquid on a polar electric crystal like LiNbO3. An array of liquid micro-lenses was generated by electrowetting effect in pyroelectric periodically poled crystals. Compared to conventional electrowetting devices, the pyroelectric effect allowed to have an electrode-less and circuit-less configuration. An interferom...

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...
