“…Most of the recently developed or planned state-of-the-art DC [32] and RF gun [33,34] based photoinjectors already have these capabilities. Using atomically ordered surfaces in such photoinjectors should be possible without difficulty.…”

“…The 1.6-cell RF gun has been used for various applications such as electron sources in high-gain single-pass FELs [17][18][19], THz coherent radiation sources [20][21][22][23][24], Compton X-ray sources [25], and ultrafast electron diffraction (UED) [26] following its invention [27]. The 1.4-cell RF gun has recently been proposed to generate high-brightness electron beams, and is considered to be used for a high-gain single-pass FEL driver linac [28] and UED [29]. In this paper, we will report on the result of the particle-tracking simulation that we conducted on the RF gun section to determine the structure of the RF gun.…”

A project is underway that aims to generate attosecond pulses via high-harmonic generation in rare gases, driven by extremely short and highly intense pulses from free-electron-laser oscillators. For this purpose, it has been planned that a new photocathode RF gun, dedicated to high-bunch-charge operation, will be installed at the KU-FEL (Kyoto University Free Electron Laser) oscillator facility. In this study, RF guns with two different structures (1.6-cell and 1.4-cell) were compared, from the perspective of exploring the possibility of introducing bunch-interval modulation, which is important for achieving high extraction efficiency in the FEL oscillator. As a result, it was confirmed that the introduction of bunch-phase modulation would be possible only in the case of the 1.6-cell RF gun. After the structure of the RF gun was decided on, particle-tracking simulations were performed, to study the electron-beam parameters using the 1.6-cell RF gun and 1 nC bunch charge. The results showed that we could obtain the peak current of 1 kA without a large degradation of the other parameters.
