Validation of conformal radiotherapy treatments in 3D using polymer gel dosimeters and optical computed tomography
(2008-12-18)Polymer gel dosimeters are a three dimensional (3D) dosimetry system that may be conveniently applied for verifying highly conformal radiation therapies where standard dosimetry techniques are insufficient. Polymer gel ... -
A Vertical Coarse Approach Scanning Tunneling Microscope
(2009-06-25)A Pan-style scanning tunneling microscope (STM), with a vertical coarse approach mechanism, was designed, built and tested. The microscope will be operated in ultra-high vacuum and also at cryogenic temperatures (8 K) ... -
The Volume of Black Holes
(2012-06-06)The invariant four-volume ($\mathcal V$) of a complete four-dimensional black hole (the volume of the spacetime at and interior to the horizon) diverges. However, if one considers the black hole resulting from the gravitational ... -
The White Beam Steady-State Diffractometer: A Next Generation Neutron Diffraction Strain Scanner
(2009-04-24)This project proposes a reactor-based instrument, which retains most of the above advantages of spallation source engineering instruments, while maintaining the advantages inherent to steady-state instruments. The main ...
