FLASH (Free Electron Laser in Hamburg) is the first FEL in the world to deliver ultrashort radiation pulses in extreme ultraviolet and soft X-ray ranges, currently being upgraded at DESY within the FLASH2020+ plan. The upgrade covers implementing new tunable undulators, improving the beam energy to 1.35 GeV, and a complete redesign of the FLASH RF Reference Generation System. That system...
The complete knowledge of electron bunch properties is of great interest to understand and optimize the performance of accelerators and their applications. A new tomographic beam diagnostics method to reconstruct the full 5-dimensional phase space (x, x', y, y', t) of bunches has recently been proposed. This method combines a quadrupole-based transverse phase-space tomography with the variable...
Commercial electron microscopes with a few hundred keV energies are fundamental tools for understanding the micro- to nano-scale world. One of the frontiers in electron microscopy development is to push the beam energy to MeV range to achieve improved lateral resolution for thick samples. Here we show the theoretical and preliminary experimental analysis of the electron beam quality required...
