A SUMMARY OF THE INTERNATIONAL DISCUSSION
MEETING ON RADIATION EFFECTS ON SUPERCONDUCTIVITY*

INTRODUCTION
The effects of radiation on the properties of superconductors was the
subject of an International Discussion Meeting held at Argonne National
Laboratory, June 12-16, 1977, and was attended by 80 scientists from 7
countries. The program focussed on radiation effects on reversible and
irreversible properties, fundamental fluxoid-defect interactions, radiation
considerations for fusion magnets, and ion implantation in superconductors.
It is well known that the properties of a superconductor depend on
the arrangement of the atoms in a crystalline solid. It is possible to
change the positions of the atoms, i.e., introduce defects, by irradiating
the superconductor with various particles. The changes in the superconducting
properties depend on the type of defect structure introduced, which in turn
depends on the type and energy of the irradiating particle, the irradiation
temperature, and the characteristics of the target material. Radiation is a
convenient method to study the role of defects on the superconducting properties
since size and number density can be introduced in a controlled fashion, and
the role of defects can be investigated without changing the chemical composi-
tion. Although research has been conducted in this field for fifteen years,
this was the first meeting on this topic and was held at this time due to the
increased interest in A-15 compound superconductors and the superconducting
composites that will be used in fusion magnets.

Laboratory, the National Science Foundation and the Division of Magnetic Fusion
Energy, of the USERDA.
