Parasitic cavity losses in SPEAR-2

In PEP the large number of particles in a bunch, together with the small bunch length, may cause grievous energy loss from the beam to parasitic modes in the accelerating cavities. The same energy loss mechanism may also influence significantly the operation of SPEAR-2. Unfortunately, there is some quantitative uncertainty in the theory of these losses -- in part, because the consequences of the approximations used are not well understood. As it stands, however, the theory does give an estimate of the energy loss that, if correct, would require a notable increase in the required rf power of high-luminosity storage rings. To obtain a more reliable value of energy loss, the best way to do so would be an experimental measurement of the loss in SPEAR-2. In this note, some of the considerations are brought together that might bear on an experimental investigation of the loss using SPEAR-2.
