3. The ThomX X-ray factory Construction will start this year, 1rst beam: 2017
A design based on
Compton
back-scattering
electron bunch
Goal :

X-ray beam
1017 photons
interaction
point
Challenges
Laser/cavity synchronization: bunch length ~3 mm (10 ps)
Waist dimension ~70 mm
Precise alignment and mechanical stability of the mirrors
Power on the mirror surfaces ~ MW
2.1 m

RF and feedback section
Injection / extraction section
IP 1
~ 8 m
Ne ~1010, E = 50 – 70 MeV
linac
Challenges: low energy –>no damping –> beam heating due to the Compton back-scattering process
–> 50 Hz injection rate

6. Making photons and electrons collide

7. APPLICATIONS
Bio-medical imaging (K-edge digital subtraction imaging (KEDSI) method )
Radiotherapy
Materials science: diffraction and spectroscopy experiments
Cultural heritage investigations
Laser+optical cavity: High energy g ray beams
