The New Facility, compared with Current Facilities, will benefit from:

i. A lower electron beam energy, due to the enhanced undulator performance.

ii. Being significantly more compact due to lower energy and X-band high-

gradient structures.

iii. Having a much lower electrical power demand than current facilities.

iv. Having much lower construction and running costs.

This will facilitate the widespread development of X-ray FEL Facilities across

Europe and beyond, by making their construction and operation costs more

affordable through an optimum combination of emerging and innovative

accelerator technologies.
