description:
	Thermal diffuse scattering images of single crystal Nb will be taken
	 over a wide temperature range (RT - base displex temperature).  We will
	use a transmission geometry with image plate or CCD as an area detector.
	
	Time permitting, images will also be taken in the presence of a small
	(2 kGauss) magnetic field in order to supress the superconducting
	 phase.

equipment+required:
	displex, CCD

experiment:
	Determination of phonon dispersions of elemental Nb through x-ray thermal diffuse scattering

foreign+nationals:
	

hazards:
	No special procedures needed.  All samples are in solid form and stable
	in air.  Do not ingest or inhale
