	The usage of x-ray free electron laser (XFEL) in femtosecond nanocrystallography involves sequential illumination of many small crystals of arbitrary orientation. Hence a wide radiation bandwidth could be useful in order to obtain and to index a larger number of Bragg peaks used for determination of crystal orientation. Considering the baseline configuration of the European XFEL in Hamburg, and based on beam dynamics simulations, we demonstrate here that usage of corrugated structures allows for a considerable increase in radiation bandwidth. It allows for data collection with a 3% bandwidth, a few micrjoule radiation pulse energy, a few fs pulse duration, and a photon energy 4.1 keV.

	We discuss recent developments of numerical methods for computation of wakefields excited by short bunches in accelerators. They include a low-dispersive computational algorithm, conformal approximation of the boundaries, surface conductivity, and indirect wake potential integration. The implementation of these methods in the electromagnetic code ECHO for 2D and 3D problems are presented with a special emphasis on a new ECHO2D code for fast calculations of wakefields in rectangular geometries. Several examples of application of the code to calculation of wakefields for the European Free Electron Laser project and in the Linac Coherent Light Source (LCLS) project are considered.

The usage of x-ray free electron laser (XFEL) in femtosecond nanocrystallography involves sequential illumination of many small crystals of arbitrary orientation. Hence a wide radiation bandwidth could be useful in order to obtain and to index a larger number of Bragg peaks used for determination of crystal orientation. Considering the baseline configuration of the European XFEL in Hamburg, and based on beam dynamics simulations, we demonstrate here that usage of corrugated structures allows for a considerable increase in radiation bandwidth. It allows for data collection with a 3% bandwidth, a few micrjoule radiation pulse energy, a few fs pulse duration, and a photon energy 4.1 keV.
