Abstract :
The principal problem, which arises at construction of multibeam cathode units, is provision of small spread in emission parameters of separate emitters in the unit preserving the mechanical strength and the shape stability of the cathode unit. The problem is reduced to task of effective attachment of emitters to their seats in the holder of the unit.
