Title:
電子ビーム源の寿命を延ばす方法、電子ビーム源及びコンピュータプログラム製品
Document Type and Number:
Japanese Patent JP6793191
Kind Code:
B2
Abstract:
The present invention relates to a method for prolonging lifetime of a triod electron beam source when forming a three-dimensional article through successively depositing individual layers of powder material that are fused together so as to form the article, the method comprising the steps of: adjusting a cathode heating power at a predetermined value above a threshold heating value, which threshold heating value creates a predetermined X-ray signal emanating from the triod electron beam source, fusing the three-dimensional article with the electron beam source having the cathode heating power at a predetermined value above a threshold heating value.
