Analysis of RF Scenarios for the PS2

This note analyses the two main RF scenarios that are presently being considered for the PS2. One option is based on a wide-band 10 MHz system and, to a large extent, follows the approach already established in the existing PS machine. The other considers a 40 MHz system for the principal RF and is motivated by the possibility of chopping at up to 40 MHz as foreseen for the SPL, the proposed PS2 injector. The aim of the analysis is not only to estimate the hardware requirements – such as the number of different RF systems needed and their voltage specifications – but also to understand from the RF standpoint the interplay between machine performance and design – such as the dependence of cycle lengths on gamma at transition.
