The purpose of the Fermilab III upgrade program is to extend the discovery potential of the Fermilab accelerator complex during the period leading up to the use of the SSC, and to leave Fermilab in a flexible position at the start of the SSC era. In particular, the collider physics goal is to achieve a luminosity greater than 5 x 10³¹ cm^-2 sec^-1, in order to: 1) guarantee observation of the top quark within the framework of the standard model, 2) double the mass reach for as yet unobserved particles, and 3) reach the factory domain in the production of W's, b's, and t's. At present (1988-89) the maximum luminosity is about 1.6 x 10³⁰ cm^-2 sec^-1. The upgrade program affects all of the Fermilab accelerators. During collider run III, new low beta optics will operate in the Tevatron, the proton and antiproton orbits will be separated to allow for a larger number of bunches, and there will be significant improvements in the Antiproton Source. A rebuilt Linac will inject protons into the Booster at twice the present energy, during collider run IV. A new synchrotron, the 150 GeV Main Injector, will replace the Main Ring in delivering high energy protons and antiprotons to the Tevatron, during collider run V. In order to achieve the goal of a factor of 30 increase in maximum luminosity, all of the Fermilab accelerators will be stressed further by higher performance demands. The Fermilab III Instabilities Workshop was created as a forum in which experts and friends from accelerator laboratories around the world could convene to discuss and evaluate the threat posed by the various instabilities which might be expected. Four major areas of potential instabilities were identified, and were separately attacked by working groups. The groups were Ion Trapping, Longitudinal Instabilities and Impedances, Transition Crossing, and Transverse Instabilities and Impedances. The proceedings which follow are also organized under the same four headings. They record the work that was performed during and immediately after the workshop, and constitute a reference source which will be valuable for a long time to come.
