description:
	We will use x-ray microdiffraction to carry out feasibility studies for temperature-dependent studies of epitaxial manganite (LaPrCaMnO3) films on various substrates.  The substrates will include systems providing lattice-matching (SrLaGaO4), in-plane tensile stress (SrTiO3), and in-plane compressive stress (LaAlO3).  We will test our ability to map changes in local strain fields over a fixed 2D area at temperatures down to ~80K.

equipment_required:
	Eliot Specht's small cryogenic stage for 34ID-E

z34ID_change_undulator:
	yes

z34ID_details:
	This experiment on 34ID-E will require on-axis beam (for monochromatic measurements) and either a tapered or scanned undulator (over a small range).  These conditions may not be ideal for operations on 34ID-C.

z34ID_on_axis:
	yes

z34ID_parasitic:
	no

z34ID_taper:
	yes
