The charge collected from beta source particles in single pad detectors produced on p-type Magnetic Czochralski (MCz) silicon wafers has been measured before and after irradiation with 26 MeV protons. After a 1MeV neutron equivalent fluence of 1x10 cm the collected charge is reduced to 77% at bias voltages below 900 V. This result is compared with previous results from charge collection measure...

Based on the invention and widely application of the Czochralski pulling method, vanadate crystals have been grown and commercialized in recent decades. In this paper, the growth and characterization of a series of neodymium doped vanadate crystals have been reviewed, including Nd:YVO4, Nd:GdVO4, and Nd:LuVO4. The excellent thermal-mechanical and laser property make them to be used in many resp...

A Czochralski-grown single crystal of GAGG:Ce,Mg allows for a high Ce dopant and Mg codopant concentration in the crystal, resulting acceleration scintillation decay down to several nanoseconds at expense light yield.

This work proposes a control configuration and a nonlinear multivariable model-based feedback controller for the reduction of thermal gradients inside the crystal in the Czochralski crystal growth process after the crystal radius has reached its final value. Initially, a mathematical model which describes the evolution of the temperature inside the crystal in the radial and axial directions and...

Abstract The compositional effect of Mo/W ratio on linear, nonlinear absorption and optical limiting behavior the NaBi(Mo x W 1−x O 4 ) 2 single crystals grown by Czochralski technique was investigated. X-ray diffraction patterns studied presented well-defined peaks associated with tetragonal crystalline structure. performance threshold were determined using an open-aperture Z-scan technique. A...

Yttrium calcium oxoborate (YCOB) and Nd:YCOB crystals of high optical quality and large dimension have been grown by the Czochralski method. Measurements of refractive indices have confirmed that these crystals were negative biaxial. The absorption spectra were determined and the various spectrum parameters were calculated. Polarized absorption spectra revealed the strong anisotropic character ...
