Description
Inverse Compton Scattering (ICS) sources are becoming more popular as future lab-based x-ray sources. Smart*Light is one such facility, under commissioning at Eindhoven University of Technology (TU/e). This compact X-ray source aims at bridging the gap between conventional lab X-ray sources and synchrotrons.
A 100 kV DC photo electron gun is used in combination with a bunching cavity to produce electron bunches that are injected in a X-band accelerator. The high gradient X-band accelerator is adapted from an original design for the Compact Linear Collider (CLIC). The accelerated electron bunches are focused and collide with a focused 12 mJ/pulse 800 nm laser beam thereby producing X-ray photons with energies between 10 and 40 keV. The physical basis behind the production of the X-rays is the ICS process in which photons from the laser pulse are bounced off a relativistic electron bunch, turning them into X-ray photons through the relativistic Doppler effect.
This work introduces the design of the low- and high power RF system, gives an overview of measurements of the electron bunch quality, and shows the first results of conditioning the high gradient accelerator.
This work is financed by the "Interreg programme Flanders-Netherlands" with financial support of the European Fund for Regional Development.
