AbstractThe paper presents a general theoretical framework and related Monte Carlo simulation of novel type of the X-ray sources based on relativistic Thomson scattering of powerful laser radiation. Special attention is paid to the linac X-ray generators by way of two examples: conceptual design for production of 12.4 keV photons and presently operating X-ray source of 29.4 keV photons. Our analysis shows that state-of-the-art laser and accelerator technologies enable to build up a compact linac-based Thomson source for the same X-ray imaging and diffraction experiments as in using of a large-scale X-ray radiation facility like a synchrotron or Thomson generator based on electron storage ring.

Illumination Mode

A high-efficiency photovoltaic module optimized for converting the monochromatic radiation with a wavelength of 809-850 nm is presented. The module comprises four photovoltaic converters with the total area of 16 cm2, which can provide the operating voltage of 4 V in the case of laser power greater than 1 W. The laser power converters are developed on the basis of AlGaAs/GaAs structures grown by LPE and MOVPE. When operating in the uniform illumination mode, the efficiency of the photovoltaic module is found to exceed 60% for the powerful laser radiation (6.2 W).

Gas Cavity

It was found experimentally that when the water surface is heated by CW laser radiation through the optical fiber with a wavelength of 1.94 μm, jets are generated : one is submerged, directed inward liquid, the other directed in the opposite direction into the atmosphere. Jets are formed when the gas cavity collapses, arising in the process of explosive boiling of water caused by absorption of laser radiation directly under the fiber tip. The mechanism of jet formation is discussed.
