This work package focuses on synchronisation issues of the FEL machine design. The new generation free-electron lasers aim to provide coherent, short-pulse (i.e. femtosecond), short-wavelength radiation pulses for user experiments. Consequently, two challenging objectives need to be combined:

First, many devices need to operate synchronous on sub-picosecond timescales.
Second, this synchronisation needs to be maintained over many hours of operation.

Compared with present-day third generation synchrotron sources, the demands on synchronisation in terms of temporal resolution and capability will increase by three orders of magnitude. Reaching these goals is non-trivial and still requires significant technological development.
