Compact Hard X-ray Source via Inverse Compton Scattering Based on the X-band Linac
نویسندگان
چکیده
We are designing a compact inverse Compton scattering hard X-ray (33 keV) source based on X-band linac. X-band 1.5and 3.5-cell photocathode RF guns and X-band linac were analyzed with PARMELA simulation, and X-ray flux was estimated for several types of lasers. The theoretical scaling law of the RF guns among charge, emittance, and RF wavelength is confirmed by PARMELA. The maximum RF field at the cathode surface should be higher than 300 MV/m. The X-ray was 1.6 x 10 photons/shot for a 10 TW 1 ps laser. Since 10 photons within 10ms is required for dynamic angiography, we considered multiple collisions using multibunch beam and multipath optics to increase the flux.

متن کاملLinac-based Laser Compton Scattering X-ray and Gamma-ray Sources
Laser Compton scattering (LCS) light sources can provide high-energy photons from keV to MeV range. Many research and development projects of linac-based LCS sources are carried on. For the photon energies of tens keV, linac-based LCS sources realize laboratory-size X-ray sources, of which performance is potentially comparable to 2 generation synchrotron light sources. Linac-based LCS also real...

Quantum radiations sources such as a laser Compton scattering (LCS) X-ray and coherent THz radiation sources have been developed on the basis of the S-band compact electron linac at AIST in Japan. The compact Xray source is required for biological, medical and industrial science because it has many benefits such as short pulse, quasi-monochromatic, energy tunability and good directivity. The X-...
متن کاملHard X-ray phase-contrast imaging with the Compact Light Source based on inverse Compton X-rays.
The first imaging results obtained from a small-size synchrotron are reported. The newly developed Compact Light Source produces inverse Compton X-rays at the intersection point of the counter propagating laser and electron beam. The small size of the intersection point gives a highly coherent cone beam with a few milliradian angular divergence and a few percent energy spread. These specificati...
متن کاملAll-laser-driven Thomson X-ray sources
We discuss the development of a new generation of accelerator-based hard X-ray sources driven exclusively by laser light. High-intensity laser pulses serve the dual roles: first, accelerating electrons by laser-driven plasma wakefields, and second, generating X-rays by inverse Compton scattering. Such all-laser-driven X-rays have recently been demonstrated to be energetic, tunable, relatively n...
