Abstract

The latest gyrotron included Gyrotron FU CW Series, Gyrotron FU CW III is introduced in detail. It consists of a 20T superconducting magnet, a demountable gyrotron tube, a 30 kV, 0.5 A, CW power supply for electron gun and additional coils in a gun region. The gyrotron has achieved the breakthrough of 1 THz and frequency step tunability up to around 540 GHz for fundamental operations and up to 1.08 THz for second harmonic operations. Application of the gyrotron to high frequency DNP-NMR is considered breafly.
