Effect of feedback and noise on fast ion instability

  • 1. Stanford Linear Accelerator Center, Stanford University, Stanford, CA (United States)

Description

One can use a feedback system to suppress the fast ion instability. However, the feedback noise (and also other sources of noise in the machine) continuously excites the transient oscillations in the electron beam that are amplified through the electron interaction with the ions. We calculate the equilibrium level of these oscillations under the influence of the feedback and show how they grow exponentially from the head to the tail of the bunch train in a linear theory. Nonlinear saturation effect are assumed negligible. (author)
