can have certain predictive power and Will give some insight for the
future acceleratoro.
There in also some hope to find suitable theoretical ground for
the accepted dependencies in the nuerical onalyis of the problem.
Much work is needed in thin respect.
In this work I suggest ne..e o.aling laws for the luminonity,
space charge parameters, and bes, i-. as functions of particle energy,
maxim bean current, and the nuber of bunches. Tnese scaling Inws
are derived iron the latest experimental data available now.
The biggest drawback of the description suggested hone, as I see
it, lieu, contrarary to the noservatione, in the complete absence of
the fitting parameter dependence on the machine tune. This drawback
can be attributed to an averaging procedure needed for a diffusion-
like description of the process. By this averaging all resonance
structure of the particle motion is completely lost. It is probable
that the resonance and diffusion approaches could be comple.entary to
each other. Again much nork is needed here.
Section 1 of this work is devoted to the recent experimental
results from SPEAR4, ADONE, and PETRA.h In Section 2 the diffusion
theory is ased to derive main relationships and, together with the
experimental results, to get min scaling laws. In Section 3 we son-
narite these scaling laws, and In Section 4 some predictions for
future storage rings are daon based upon the scaling lao.
