Substantial increase in acceleration potential of pyroelectric crystals
Repository Usage Stats
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.

Professor Emeritus of Physics
Professor Werner Tornow became the Director of TUNL in July, 1996. He is primarily interested in studying few-nucleon systems with special emphasis on two-nucleon systems and three-nucleon force effects in three-nucleon systems. Polarized beams and polarized targets are essential in this work. He collaborates with the leading theoreticians in his field to interpret the experimental data obtained at TUNL. He recently became involved in weak-interaction physics, especially in double-beta decay s
