Title A semi-analytic, matrix-based model for the beam arrival time jitter
Contributors
Abstract The beam arrival time jitter is an important parameter for many advanced electron accelerators, including next-generation XFEL drivers. Accurate jitter modelling is particularly important during the design of a new facility, where it is often used to determine the tolerances of the RF sources and photoinjector laser. Conventionally, jitter is modeled using computationally intensive start-to-end simulations; in this approach, the entire accelerator is simulated many times, while the parameter associated with each jitter source is varied within its expected tolerance. This approach is time-consuming and scales poorly with the size and complexity of the accelerator. Semi-analytic jitter models therefore have significant advantages, owing to their speed and greater insight into the underlying physics. In this contribution, we propose a simple matrix-based model for the arrival time jitter in a linear accelerator with an arbitrary layout. We validate the model against simulations of CLARA at Daresbury Laboratory, and use it to explore the jitter tolerances of different operating modes.
