# UNICAT Member Beam Time Request  #68

days:
	6

description:
	The experiments will consist of two separate activities. The first is
	USAXS data acquisition on systems that have been measured before:
	MgAl2O4 spinels, Portland cements, bicalcium nitrate (simplified
	cement), phase development in polymers, growth of silica crystals.
	The second is a commissioning exercise for installing (and using for
	the first time) the side reflection stages. These stages will give us
	essential pinhole collimation, enabling experiments on anisotropic
	materials. The first materials that will be tested will be yttria-
	stabilized zirconia plasma-sprayed layers, and Fe2TiO5.
	

equipment+required:
	

experiment:
	microstructure of polymers %26 cements; side-refl. stage commissioning

hazards:
	There are no safety issues associated with any of these materials.

name:
	Gabrielle Long, Andrew Allen, Jan Ilavsky, Pete Jemian

nonmembers:
	Valeria Tohver (U. of Ill.)

station:
	33ID-D

unacceptable+dates:
	We are requesting the last 6 days of the cycle in September, in the
	hope and expectation that the side-reflection stages will be ready
	for installation.
	
	The polymer phase development research can be done with one day of 
	beamtime in July or August, if that's available.
