The top energy parameters of gyrotrons depend on the quality of helical electron beams ( HEB) which are formed mainly by magnetron injection guns (MIG). The limitations of the HEB current are related to the instability which has various specific manifestation (increase of noise,spontaneous growth of the emitting current,breakdowns), but always cause a sharp worsening of the HEB quality. Below some factors leading to the HEB instability are considered. 1. The beam potential depression are more… CONTINUE READING
