とどめてもよい。 In FIG. 1, a linear hot cathode 1 is connected to a cathode support 1.
4 maintains a distance from the back electrode means 2. Further, the back electrode means 2 and the extraction electrode means 3 are configured such that a distance between them is maintained by other means. The cathode support 14 is made by fusing a softenable glass 16 to the outer periphery of a high melting point metal wire 15 made of, for example, an alloy of iron, nickel, and chromium. As shown in FIG. 2a, by heating the cathode support 14 to the softening point of the softenable glass in advance, it is fixed to the back electrode means 2 and at the same time is insulated from the linear hot cathode 1. It will be done. Further, at the bonded portion, the metal wire 15 of the cathode support 14 is exposed as shown in FIG. 2b, and the cross section is formed into a convex shape. After that, the cathode support 1
The linear hot cathode 1 is stretched so as to be perpendicular to and in contact with the hot cathode 4. As mentioned above, the cathode support 14 is for maintaining the distance between the back electrode means 2 and the linear hot cathode 1. However, as shown in FIG.
It is not necessarily necessary to provide the electron beam through hole 6 in the middle portion thereof. It is the support 14
This is because the surface of the capacitor is made of metal, so no electric field sag due to charge up or the like occurs.
Furthermore, it is not necessary to provide a plurality of the supports 14 at regular intervals, and they may be kept to a minimum as long as the intervals can be maintained and the vibrations of the linear hot cathode 1 can be suppressed.
第１図においては、背面電極手段２上に設けた
陰極支持体１４について述べてきたが、この陰極

In other words, it is not fixed to the material. Further, the adhesive glass used around the metal wire is not limited to softening glass, and for example, low melting point fritted glass or the like may be used.

Since it is composed of an exposed high melting point metal wire and a glass adhesively fixing the high melting point metal wire to the back electrode means or the extraction electrode means, the distance between the linear hot cathode and the back electrode means or the extraction electrode means can be maintained reliably. , and the influence of the cathode support provided there can be eliminated.
