“…This is the value of linac frequency considered in the design of the next generation CW light sources involving warm and cryogenic accelerator structures [16,18]. To achieve it, the problems connected with radiation and electrical damage of cathodes and availability of photocathode UV lasers (see [11]) are to be solved. The storage ring in LEXG reduces the linac frequency down to 0.5-5 kHz for single bunch injection (see further this section) and no problems arise with the cathode and photocathode laser.…”

X-ray generators utilizing Thomson scattering fill in the gap that exists between conventional and synchrotron-based X-ray sources. They are expected to be more intensive than X-ray tubes and more compact, accessible and less expensive than synchrotrons. In this work, two operation modes of Thomson X-ray source are documented: quasi CW (QCW) and a pulsed one are considered for material sciences and medical applications being implemented currently at Synchrotron Radiation (SR) facilities. The system contains a ~50 MeV linac and a few picosecond laser with an average power ~few hundred Watts. The Thomson X-ray source is able to deliver up to 5·10 11 photons in a millisecond flash and an average flux of 10 12 -10 13 phot/sec. To achieve these parameters with existing optical and accelerator technology, the system must also contain a ring for storage of ebunches for 10 3 -10 5 revolutions and an optical circulator for storage of laser pulses for 10 2 passes. The XAFS spectroscopy, small animal angiography and human noninvasive coronary angiography are considered to be possible applications of the X-ray source.

“…These sources are expected to fill the gap existing between conventional X-ray tubes and large accelerator-based facilities with respect to X-beam intensity, tunability, size, power supply, cost, etc. (Bessonov et al, 2007(Bessonov et al, , 2009Gorbunkov et al, 2009).

The 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.
