Abstract
Irradiation equipment comprising a beam duct disposed along the synchrotron radiation beam, and a multistage axial flow turbine installed in the beam duct. The multistage axial flow turbine comprises a plurality of stators and rotors arranged alternately in an axial direction. Each stator has vanes and a beam transmission hole formed through the vane region. Each rotor has vanes and gaps between adjacent vanes. A plurality of beam transmission holes are aligned in a direction of the synchrotron radiation beam, and a plurality of gaps of the rotors are intermittently aligned in the direction of the synchrotron radiation beam, whereby the synchrotron radiation beam can intermittently penetrate through the multistage axial flow turbine through the beam transmission holes and gaps with rotation of the rotor.
