Study of emission properties of tungsten single crystal with crystallographic orientation <310>
Original language description
The aim of the work was to determine the emission pattern of tungsten single crystal with crystallographic orientation of the growth axis <310> prepared by the electron beam zone melting applying the ?floating zone? method as a new type of prospective material for production of electron emitters. For this purpose, first of all, we had to prepare a crystal nucleus of the corresponding orientation applying our own technology. The orientation of the axis of the obtained tungsten single crystal was checkedby the classical X-ray Laue method of back reflection followed by an evaluation. The testing of emission properties itself was carried out in the firm DELONG INSTRUMENTS a.s. Brno in terms of direct co-operation, where an emitter was made of the given tungsten single crystal sample. The obtained emission pattern was excellent and it can be stated that the given tungsten single crystal meets all requirements on production of emitters for electron microscopy.
