Advancement of oscillation efficiency by improvement of electron beam quality in Gyrotron FU CW GIA

In experiments of Gyrotron FU CW GIA, improvement of the energy conversion efficiency was investigated by two approaches; one is reducing the misalignment between the cavity and magnetic coil axes. The other is the design modification of the magnetron injection gun (MIG) to suppress the electron vel...

Summary:In experiments of Gyrotron FU CW GIA, improvement of the energy conversion efficiency was investigated by two approaches; one is reducing the misalignment between the cavity and magnetic coil axes. The other is the design modification of the magnetron injection gun (MIG) to suppress the electron velocity spread at the cavity. The two effects were separately examined. As a result, increases in the efficiency were obtained by both the reduction of the misalignment and the modification of MIG.
