Spectral modulation of higher harmonic spontaneous emission from an optical klystron

Using the infrared free-electron laser system of the storage ring NIJI-IV, some unique characteristics of the higher harmonics emitted from an optical klystron have been clarified.

Visualization of microvessels by angiography using inverse-Compton scattering X-rays in animal models

The fundamental performance of microangiography has been evaluated using the S-band linac-based inverse-Compton scattering X-ray (iCSX) method to determine how many photons would be required to apply iCSX to human microangiography.
