Abstract :
Two sealed-off gyrotron tubes for high power THz spectroscopy are designed and constructed. One of them will be used for ESR echo experiment in sub-THz region, and another for 600 MHz DNP-NMR experiment etc. Both gyrotrons are named Gyrotron FU CW IIA and Gyrotron FU CW VIIA, because their cavities have same shapes as Gyrotrons FU CW II and FU CW VII. Both tubes are installed in 8T superconducting magnets. The operation mode is CW or long pulse.
