Method of bonding amorphous carbon material with metal material or ceramic material, and electron tube device

An electron tube device having a sealed space, said device comprising:

• a vessel having an opening portion, a peripheral portion of which is made of at least one member selected from the group consisting of at least one metal material and at least one ceramic material;
• a window made from an amorphous carbon film and bonded to said peripheral portion of said opening portion;
• means for emitting electrons;
• means for accelerating the emitted electrons toward an X-ray generating metal target provided in said vessel;
• and
• means for focusing the emitted electrons on a surface of said target so that the generated X-rays are output through said window.

An electron tube device having a sealed space, said device comprising:

• a vessel having an opening portion, a peripheral portion of which is made of at least one member selected from the group consisting of at least one metal material and at least one ceramic material;
• a window made from an amorphous carbon film and bonded to said peripheral portion of said opening portion;
• a gas sealed in the space and ionized by the X-rays incident through said window;
• and
• means for amplifying ionization of said gas.

An electron tube device having a sealed space, said device comprising:

• a vessel having an opening portion, a peripheral portion of which is made of at least one member selected from the group consisting of at least one metal material and at least one ceramic material;
• a window made from an amorphous carbon film;
• and
• a Ti containing brazing material bonding said window to said peripheral portion of said opening.
