THERMIONIC ELECTRON EMITTER, METHOD FOR PREPARING SAME AND X-RAY SOURCE INCLUDING SAME |
摘要 |
<p>A thermionic electron emitter (1) is proposed comprising an emitter part (2) with a substantially flat electron emission surface (3) and a bordering surface (5) adjacent thereto. In order to better absorb main stress loads (L) induced by external forces, the emitter part is provided with an anisotropic polycrystalline material having a crystal grain structure of elongated interlocked grains the longitudinal direction (G) of which is oriented substantially perpendicular to the direction (L) of the main stress loads occurring under normal operating conditions.</p> |
