A laboratory based system for laue micro x-ray diffraction.

A laboratory diffraction system capable of illuminating individual grains in a polycrystalline matrix is described. Using a microfocus x-ray source equipped with a tungsten anode and prefigured monocapillary optic, a micro-x-ray diffraction system with a 10 microm beam was developed. The beam profile generated by the ellipsoidal capillary was determined using the "knife edge" approach. Measurem...

Ultra - high field imaging techniques for MRA

• Performing magnetic resonance angiography (MRA) at higher fields has been demonstrated to improve the signal to noise and contrast to noise in both the brain and body applications. • Direct implementation of standard clinical protocols and acquisitions methods at 7T are insufficient to obtain the best results as increased B0 and B1+ inhomogeneity, local SAR and limited peak power present road...

Sonoluminescence and the prospects for table-top micro-thermonuclear fusion

Hydrodynamic simulations of a collapsing bubble show that pure D, cannot exhibit picosecond sonoluminescence, because of its large sound speed. The addition of D,O vapor lowers the sound speed and produces calculated results consistent with experiments. A pressure spike added to the periodic driving amplitude creates temperatures that may be sufficient to generate a very small number of thermon...
