DEVELOPMENT OF INTENSE TERAHERTZWAVE COHERENT SYNCHROTRON RADIATIONS AT LEBRA

To obtain an intense light source in the terahertz region, we developed coherent synchrotron radiation (CSR) using an S-band linac at Laboratory for Electron Beam Research and Application in Nihon University. Intense radiation was observed in the D-band region and it was confirmed to be the CSR. The two-dimensional distribution of the CSR was measured, and the CSR reflected in the vacuum chamber of the bending magnet was found to be emitted through the quartz window for a few tens of picoseconds.
