Highlights of a workshop on synchrotron radiation intrumentation and macromolecular crystallography, a satellite meeting of the 4th International Conference on Synchrotron Radiation Instrumentation, will be presented. The theme of the meeting was to look towards the developments on the next generation of high brilliance SR sources current under construction. Macromolecular crystallography needs span a very wide range of technical requirments covering the most demanding uses of SR. It is a rapidly expanding field. (AIP)
