	34ID-E

	No

days:
	7

description:
	Plastically deformed Cu (5% compression) sample will be measured to discover the dislocation cell structure  and the strain level at cell walls and interior of the dislocation cells. Regular X-ray measurement reported 20 years ago shows the local strain having opposite sign at wall and interior of the cell. X-ray microdiffraction will be able for the first time to check the micromechnism of dislocation network.
