Summary
The electric field carried along by a SLC bunch is very intense at the surface of the bunch because of the bunch's tiny transverse dimensions and its high charge density. For a given bunch population, the maximum electric field - which occurs at the surface - is inversely proportional to the bunch radius for a round bunch. The smaller the radius, the higher the peak field. A charged particle such as an ion or an electron which is placed at rest in the path of the oncoming bunch will be accelerated by the field as the bunch has passed having sampled the field of the bunch. Thus by placing a swarm of stationary charged particles in the path of the bunch and measuring their momentum distribution when they emerge, we can hope to infer the bunch's transverse size. We are using the terms size and surface in a qualitative way, of course, expecting that their meaning will be reasonably clear to the reader. In our calculations we use a cylindrical model for the bunch in which their meanings are precise.
