We conclude that fixed anode x-ray tubes can be used in a magnetic field although its desired electron optics must be fairly “straight” and the cathode-anode axis must be well aligned with the field.
The superiority of this cathode increases when used in high resolution, high brightness electron guns where the electron extracting field is high at the cathode surface.
It is concluded that the Li y Ni 1-x Co x O 2 cathode could represent a promising candidate for a cathode film in TFBs.
This behavior indicates that use of simplified cathode systems and procedures is consistent with long cathode lifetimes.
The high brightness of the FE e-beam coupled with the array structure of the cold cathode allows a smoother control of the x-ray emission intensity.

How do the crystal structure and surface properties of the metal influence the adhesion process?
5 answers
The crystal structure and surface properties of metals significantly impact the adhesion process. Different metal microstructures exhibit varying levels of bacterial adhesion, with the heat-affected zone showing the highest adhesion compared to the base metal due to segregation of elements and surface roughness. Surface roughness and energy of the metal affect adhesion performance, with roughened surfaces improving adhesion, while surface energy has a minor impact. Adhesion strength is influenced by the size of surface asperities and the material of the metal specimen. Chemical interactions at solid interfaces play a crucial role in adhesion, with the presence of chemisorbed atoms altering adhesion energies, where non-metallic elements generally decrease adhesion energy except for Carbon and Boron. Delamination in chip dicing processes can be prevented by roughening silicon surfaces selectively to maintain reliable conductivity.

Does conductivity increase or decrease with dissolved oxygen?
5 answers
Conductivity tends to increase with dissolved oxygen levels. Research indicates that in the presence of higher dissolved oxygen concentrations, such as 9 mg L−1, the conductivity of water increases due to the formation of dissolved ozone and hydrogen peroxide, leading to higher conductivity levels. Additionally, a study on the effect of dissolved oxygen on the oxidation reaction of anodes in microbial fuel cells found that the current output decreased by 7% with the impact of dissolved oxygen, suggesting a correlation between dissolved oxygen and conductivity changes. Furthermore, the corrosion behavior of X80 pipeline steel in simulated soil solutions showed that as the dissolved oxygen concentration decreased, the corrosion current density reduced significantly, indicating a decrease in conductivity with lower dissolved oxygen levels.
