Abstract	:	We have studied the interactions of vortices in superconductors with surfacefeatures and sample edges. Surface steps can generate an asymmetric vortex pinningpotential and can influence the distribution of vortices upon cooling into thesuperconducting state in an applied magnetic field. The edge of a sample acts as a barrierto vortex entry into the superconductor and can have a substantial effect on the transportproperties of vortices. We have uso-' 2 .;- ming SQUID Microscope (SSM) to directlyimage the vortex distributions in v~;.o:is superconducting systems. including crystalsLvith naturally cleaved surface steps as w2ll......-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
