“…Furthermore, the experimental campaigns of the short pulse 18,19 and continuous wave 20 prototypes of the EU 170 GHz, 1 MW conventional cavity gyrotron for ITER, as well as older experiments 21 with the coaxial cavity gyrotron at KIT, identified the importance of the possible operation of the MIG in a wide range of magnetic profiles. This flexibility is very important for the optimization of the gyrotron performance under the influence of many factors which are not taken into account during the design phase of the gyrotron, such as the manufacturing tolerances and the misalignment with the magnetic field.…”

Considering the recent understanding of the physics of electron trapping mechanisms taking place in the magnetron injection gun (MIG) region of gyrotrons and the sensitivity of the emitter ring manufacturing tolerances on the electron beam quality, a MIG has been designed and manufactured for the 2 MW, 170 GHz coaxial cavity gyrotron developed at Karlsruhe Institute of Technology. The new MIG has the following novelties: (i) the design satisfies the criteria for the suppression of the electron trapping mechanisms, (ii) a new type of emitter ring is used for the suppression of the influence of the manufacturing tolerances and misalignments on the quality of the generated electron beam, and (iii) the design was optimized to generate a good beam quality in a wide variety of magnetic field profiles to increase the flexibility. An additional important feature of the new triode MIG design is the possibility to operate with only two power supplies by using a special start-up scenario. The first experimental results of the coaxial cavity gyrotron with the new MIG are presented.
