Birnbaum Materials Research Laboratory University of Illinois I n this age of introspective research funding, it is appropriate to question the funding of the microcharacterization centers in the same manner that we question other activities. While the sciences that comprise the field of microcharacterization are widely used by chemists, physicists, materials scientists and engineers, and by researchers in a number of other disciplines, microcharacterization plays an important educational role only in a limited number of fields other than materials science.

Only within the relatively small fields of metallurgy and ceramics have these methods won acceptance and respectability. The microcharacterization centers are faced with the somewhat daunting prospect of providing access to a wide range of techniques based on sophisticated instrumentation and sciences to a user base that would be greatly hampered by the absence of such access.

· Much of what is known of epitaxial growth results from the use of TEM, LEEM, STM, and x-ray methods. · Quasicrystals and their unusual symmetries were discovered using TEM methods.

The above examples, by no means a complete list, illustrate the important role played by microcharacterization science in materials science, condensed matter physics, and materials chemistry. Considering the portfolio of research at the DOE laboratories, the role of the characterization centers is perhaps greater than in the average research organization.

From page 220... ...
At many of the microcharacterization centers, the researchers make use of multiple tech niques for their studies -- indeed this is essential in addressing complex materials problems. Their very nature requires that synchrotrons and neutron scattering facilities serve large regional or national clienteles.

From page 221... ...
Thus in many ways, the large facilities and the microcharacterization centers play complementary roles in the range of DOE facilities. While they serve complementary purposes, it would be difficult to imagine a DOE research environment with either of the two types of facilities missing.
