The Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT) is the first realization of a liquid xenon time projection chamber for Compton imaging of MeV γ-ray sources in astrophysics. By measuring the energy deposit and the three spatial coordinates of individual γ-ray scattering points, the location of the source in the sky is inferred with Compton kinematics(More)
La<inf>3</inf>Ga<inf>5.5</inf>Nb<inf>0.5</inf>O<inf>14</inf> (LGN) and La<inf>3</inf>Ga<inf>5.5</inf>Ta<inf>0.5</inf>O<inf>14</inf> (LGT) with trigonal 32 symmetry were grown by Czochralski (CZ) method. High Resolution X-Ray Diffraction (HRXRD) measurement was carried out on the as-grown LGN and LGT crystals for crystal quality evaluation. Frequency(More)
High temperature piezoelectric crystals, YCa<sub>4</sub>O(BO<sub>3</sub>)<sub>3</sub> (YCOB) possess relatively high piezoelectric activities (d<sub>eff</sub> = ~7.8pC/N, k<sub>eff</sub>= ~19%) and no phase transition prior to the melting point (~1500&#x00B0;C), indicating the potential use for high temperature sensing. In this work, growth of YCOB single(More)
In this report, the dielectric and hydrostatic piezoelectric properties of the monoclinic bismuth triborate crystals (BiB<sub>3</sub>O<sub>6</sub>, BIBO) were investigated at ambient temperature for potential hydrophone application. The pressure dependence of the hydrostatic charge and voltage coefficients dielectric properties (d<sub>h</sub> and(More)
In this report, the bismuth triborate piezoelectric crystals,&#x03B1;-BiB<sub>3</sub>O<sub>6</sub>(BIBO), were investigated for potential sensor applications. The dielectric, piezoelectric and electromechanical properties were evaluated by using the impedance method, where the largest piezoelectric charge coefficients were found for d<sub>22</sub>, being on(More)
