Purpose

A two-part workshop focusing on the first observations to be made with the Green Bank Telescope (GBT) will take place in Green Bank from July 27 through 29, 1998. The purpose of this workshop is to maximize the initial scientific productivity of the GBT. The NRAO technical staff will guide tours of the GBT and its control room, and they will give status reports on the antenna, receivers, backends, laser metrology, software, and operations. Then astronomers will present short contributed papers describing their scientific goals, requirements for the GBT, and any special NRAO support which they might need. Direct interaction between the astronomers and technical staff will help the astronomers plan realistic observations and help the NRAO set priorities and performance standards for the GBT. In addition, observers with common interests are encouraged to plan collaborations or large-scale observing programs best undertaken jointly (e.g., an HI survey covering a well-defined sample of nearby galaxies with uniform resolution and sensitivity). On the evening of the second day, groups of astronomers with similar scientific goals or observing methods (e.g., pulsars, extragalactic HI, polarimetry, molecular spectroscopy, high-redshift galaxies and cosmology, VLBI, continuum imaging, 3 mm observing) will meet and draft summaries describing their fields and how the GBT might best support them. These reports will be presented on the morning of the third day. The remainder of the meeting will cover commissioning of the GBT --- collimating, pointing, and calibrating the telescope, improving its performance at short wavelengths, and making it a productive user instrument as efficiently as possible.
