Outline of Final Research Achievements |
We have conducted studies for upgrade and performance evaluation of the far-infrared or terahertz (THz) free-electron laser (FEL) based on the L-band electron linac at ISIR, Osaka University. A grid pulser for the electron gun of the linac was developed to make charge of electron bunches four times higher and consequently a high intensity THz beam with micropulse energies higher than 0.1 mJ was successfully generated at wavelengths around 70 um or frequencies around 4.2 THz, which is ten times higher than previous values obtained with FELs in the same frequency region. The linac has been also upgraded for stable and reproducible operation, so that the stability of the FEL beam becomes higher. Thus we have established bases for application experiments using the high intensity THz beam generated with the FEL.
