INSTRUCTIONS AND NOTES

The conveners of the working groups and topics for reports are listed below. The conveners will arrange plenary and working group agenda as they choose. The primary goal of the working groups will be to define the experimental program for the next two years. In particular, budget estimates for next year must be formulated very soon. People with new results to present should contact the appropriate convener directly.
