Abstract
Free-electron-laser of (FEL) oscillation at 14 mu m using a two-mode c ompact linac is reported. FEL oscillation with a net gain of 7% is obt ained using an electron beam with an energy of 24.8 MeV, peak current of 30 A, and pulse duration of 10 mu s. Since an electron beam with go od properties such as a low emittance and narrow energy spread is esse ntial for the FEL oscillation, a low-emittance gun supplied with a hig h voltage of DC -200 kV and a klystron modulator having a precise volt age stability were developed. The linac can not only be operated as a FEL source but also an injector for a synchrotron radiation ring. This is the first such linac reported and is expected to enable cost-effec tive industrial use of FEL.
