“…To study the influence of the phase velocity and amplitude variation, we provide the results of beam dynamics simulations [26] with the buncher parameters designed according to Eqs. (48), (49), and for the same linac that was described above. Both the middle and end sections have the same parameters n 0.25, m 0.11.…”

“…Here P is the gun's perveance, defined by the geometry of the gun. However, the price, dimensions and complexity of DC electron guns and power supplies grow significantly with the voltage [44,48], (mostly, due to isolation and pulsed power system complexity), and in practice are preferred to be kept around 10-20 kV for compact medical accelerators, 30-50 kV for industrial accelerators and to 80-160 kV for large high-current facilities [15,21,44,[49][50][51]. Therefore, the injection usually occurs at lower velocities than β ph , which fundamentally limits the capture of the beam.…”

“…Usually, all these elements are physically combined into a single accelerator assembly for compactness and simplicity of fabrication/operation. Such accelerators are usually designed to provide moderate beam transmission rates on the order of 30-60% [1,21,44,49]. In high-current/high-power accelerators, where high beam transmission is very important, the layout can be more complex and may include > 100 kV DC gun, separate pre-buncher and buncher and more elements as shown in Fig.…”

“…• In short bunchers (1-5 cells), the electrons are accelerated very rapidly thanks to the high RF fields, meaning that phase oscillations stop very quickly [77]. On the one hand, this allows a very simple design even with no external focusing [78], but, on the other hand, the beam transmission is usually limited to 30-50% [49,63,79].…”

The acceleration of electrons in resonant linear accelerators (linacs) typically consists of three main stages: (1) emission of the electrons from the cathode and their pre-acceleration with a DC field to the energy of tens of keV; (2) grouping the DC electron beam into bunches and their synchronization with the correct phase of high-frequency electromagnetic fields, and (3) accelerating the bunches of relativistic electrons to the required energies. Although many books describe the theoretical and practical aspects of electron linac design, most of them concentrate on beam physics in either the gun stage or in the relativistic regime, while leaving the description of the bunching process rather general. The physics of non-relativistic motion is described in the literature on ion accelerators, but in practice, it cannot be scaled to electron machines due to the significantly different particle mass and acceleration rate, beam velocity change, and frequencies. In this tutorial review paper, we will fill this gap with a detailed description of the bunching process and provide practical advice on the design of bunching sections in industrial-grade electron linacs.
