Abstract
We present measurements on the superconductor compound Bi–Sr–Ca–Cu–O, obtained using a scanning Auger microscope (SAM), which indicate that this material is extremely unstable under an electron beam with energy of several KeV, Using relatively high current densities for the SAM, it is possible to melt small regions of the material and to form spheres several micrometers in diameter in a few seconds. We characterize the changes in the elemental concentration of the surface of these spheres as a function of time after the beam exposure.
