並列タイトル等Analysis of oscillation characteristic of 300 GHz CW Gyrotron FU CW I
一般注記A 300 GHz CW Gyrotron FU CW I has been developed and installed as a power sourse of a high frequency material processing system. Its performance test was carried out and the maximum power of 1.7 kW/CW has been attained at the beam voltage Vk of 15 kV and the beam current Ik of 1 A. However, the obtained power is only a half of the designed value of 3.5 kW. Anode current and fluctuation of beam current increased with the beam voltage. To reduce them, a large anode resistance was inserted, and they have been controlled by enlarging the anode resistance.In result, we obtained 2.3 kW, a new record of the output power.The present radius of electron beam in the cavity has been shifted from that in design owing to the addition of the auxiliary magnetic coils.To optimize the beam radius determined the relation between the radius of the electron beam and auxiliary magnetic field, by utilized transition of rotational direction of oscillation mode in the cavity.
