100 mev linac
100 MeV LINAC

At present, SLEGS construction is under its primary stage. We now carrying out the construction of its proto type----a x-ray facility at 100 MeV LINAC.

100 mev linac vs co 2 laser as a sample
100 MeV LINAC vs. CO2 laser as a sample
  • CO2 laser:
    • l=10.64 [mm]  Infrared.
    • Waist radius: down to ~10 [mm]
    • Power of CW laser: up to ~1500 [W]
    • Well-developed and generally-used in industry.
    • Relatively low cost.

The differential flux changes sharply with the transform of interaction position if waist width is very small but becomes insensitive when waist width of laser is large enough.
  • Total luminous flux increases and then decreases with increase of waist width of laser. In addition, a longer wave length laser corresponds a larger total luminous flux at the same waist width of laser.
