Description
Using short RF pulses, the one-of-a-kind travelling-wave rf photogun achieves cathode peak fields of up to 180 MV/m, surpassing current S-band performance and paving the way for a brightner SwissFEL. Installed at the C-band test stand at PSI, it demonstrates robust high-power operation. We provide an overview from RF design, unique tuning free realization and high-power operation, highlighting how TW gun technology opens new opportunities for electron sources technology. Furthermore, we describe the integration of field-emission tips to realise the TW field-emission gun enabling the generation GHz bunch trains. This technology is expected to have broad impact across a range of fields, from applications requiring high average currents, such as medical therapy, to those demanding exceptionally bright beams, such as MeV electron microscopy.
