“…When it comes to radiofrequency (RF) cavities, the impact of these fields can be such that a reduction in the accelerating gradient takes place. This phenomenon is known as the beam-loading (BL) effect [3][4][5].…”

“…An alternative perspective of the BL effect is given in [16], where the beam-induced field in standing-wave (SW) cavities is explained in terms of phasors for electron storage rings, and in [3,17,18], where the BL effect is presented in terms of a power-diffusive partial differential equation (PDE), which is analyzed for beam-loading compensation.…”

The need to achieve high energies in particle accelerators has led to the development of new accelerator technologies, resulting in higher beam intensities and more compact devices with stronger accelerating fields. In such scenarios, beam-loading effects occur, and intensity-dependent gradient reduction affects the accelerated beam as a consequence of its interaction with the surrounding cavity. In this study, a power-diffusive partial differential equation is derived to account for this effect. Its numerical resolution has been implemented in the tracking code RF-Track, allowing the simulation of apparatuses where transient beam loading plays an important role. Finally, measurements of this effect have been carried out in the CERN Linear Electron Accelerator for Research (CLEAR) facility at CERN, finding good agreement with the RF-Track simulations.

“…(3) and NBS (Gaithersburg). 4) In the case of beam loading where there are multiple pulses transiting at the same time, spaced far enough apart that significant RF power is introduced between pulses, the energy gain may be calculated by dividing the waveguide into a number of segments, each equal in length to the integral of the interpulse time (T) and the local group velocity (v (z)).…”
