Note on beam--beam tune shift in single ring multi bunch mode
If many identical counter-rotating bunches of protons and antiprotons are stored in a single ring, they will have identical orbits. The question is: Is this total tune shift relevant to the problem of beam stability. The answer is: not in general. The nonlinear force is described by its ''strength'', ..delta nu../sub I/, for each bunch interaction individually. It is not at all clear that the sum of the individual ..delta nu../sub I/ is the significant quantity

ISABELLE ring structure and performance
A summary of the ISABELLE Ring Structure is presented. A phased approach to ISA operation is detailed. The initial performance potential indicates that p-p collisions at a wide range of energies and unequal energies in the two beams will be possible. The quasi 8-fold periodicity could be broken to allow a hi-luminosity set-up, which could be achieved by small changes in the insertion quadrupole strengths. A discussion is given of future ISA phases requiring the alteration of the physical layout of the insertions for various special experimental conditions. (auth

High energy physics in the United States
The US program in high energy physics from 1985 to 1995 is reviewed. The program depends primarily upon work at the national accelerator centers, but includes a modest but diversified nonaccelerator program. Involvement of universities is described. International cooperation in high energy physics is discussed, including the European, Japanese, USSR, and the People's Republic of China's programs. Finally, new facilities needed by the US high energy physics program are discussed, with particular emphasis given to a Superconducting Super Collider for achieving ever higher energies in the 20 TeV range.
