Sokolova, A. Konyushin, Y. Chebotarevsky, I. Popov, E. Surmenko] Laser processing techniques were used for production of fine-meshed control grids for cathode assemblies. In this paper we discuss the features of development and production of grids made of refractory materials with concentric arrangement of meshes and wires. Two different types of grid structures are studied: a pyrographite grid with thin wires and a molybdenum grid with small round meshes. The grid with concentric arrangement of meshes is connected with multibeam field-emission cathode which is also produced by laser processing techniques. High-performance, high-speed laser microperforation allows one to obtain high convergence between grid and cathode. The paper also contains an estimation of the defect zone size after the action of the laser. Springer-Verlag, 2011 Sokolova T.
