Figure 1
The Inverse-Compton Scattering X-ray (iCSX) source; (a) schematic presentation and (b) spatial X-ray energy distribution. The 4 MeV electron beams which are generated from an S-band (2856 MHz) laser photocathode radio-frequency (RF) gun and ultraviolet laser are accelerated to 40 MeV by installation in series with two 1.5 m S-band accelerator tubes. Accelerated electron beams which are deflected at a right angle by an achromatic arch collide with a titanium sapphire laser (Ti:Sa laser). The X-ray pulse of more than 106 photons s−1 thus acquired from the laser Compton scattering is characterized by quasi-monochromaticity, and a small focus size of 30–40 µm. This system can be placed within a 10 m × 10 m medium-scale laboratory (a). As shown in (b), the photon energy in the region from the centre to a distance of 10 mm exists just above the K-edge of the iodine, and could be considered as suitable for detecting a small amount of iodine in the microvessels. |
