+++ONLINE COLLOQUIUM+++ How to shrink accelerators and light sources? (Prof. Dr. X. Franz Kärtner)
The use of very high frequencies enables operation of accelerators at higher field strength with lower energetic driver pulses scaling with wavelength cube. Approaches towards a linear terahertz accelerator technology to realize ultrabright and compact electron sources for both ultrafast electron diffraction as well as X-ray sources are discussed.

Experimental results on laser based high energy terahertz generation, terahertz guns and accelerators are shown. The high acceleration fields and gradients possible in terahertz devices enable novel electron bunch manipulations, bunch diagnostic and promise ultimately fully coherent X-ray production from compact sources. First experimental results on an ultrafast electron diffractometer enhanced by THz pulse compression are shown.
