Abstract

PURPOSE:To make unnecessary a power supply of a large current capacity by providing an H-shaped iron core through which a doughnut-shaped vacuum container is passed, and winding a baking coil around the iron core, and passing an inducing current through the vacuum container. CONSTITUTION:A deflecting electromagnet iron core 10 through which a vacuum container 1 is passed is in the form of H. A baking coil 11 is provided which is wound around the deflecting electromagnet iron core 10. When an AC current is made to flow through the baking coil 11 an inducing current flows through the vacuum container 1 so that the vacuum container 1 is baked.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vacuum container baking apparatus for baking a donut-shaped vacuum container.

[Prior Art] Figure 3 is a block diagram of a vacuum container baking device used in the SOR device shown in "Design of rUVsOR Storage Ring" (Molecular Science Institute, December 1980).
(1) is a donut-shaped vacuum container, and (2) is a vacuum container (1
), (3a), (3b)
are the first and second electrodes protruding from the vacuum container (1) on both sides of the ceramic insulating part (2), and (4) is the first electrode (
3a) and the second electrode (3b).

In the vacuum container baking apparatus described above, the first electrode 8ii
(3a) and a DC power source (4) between the second electrode (3b)
By applying a voltage, current flows through the vacuum container (1) along the dotted line in the figure, and the vacuum container (1) is baked.

[Problem to be solved by the invention] In a conventional vacuum container baking device, the current flowing in the vacuum container (1) flows directly into the DC power source (4), so a DC power source (4) with a large current capacity is required. In addition, there was a problem in that a ceramic insulating part (2) had to be provided.

The present invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a baking device for a vacuum container that does not require a ceramic insulating section and a power source with a large current capacity.

[Means for Solving the Problems] A baking device for a vacuum container according to the present invention includes an H-shaped iron core through which a vacuum container is provided, and a baking coil wound around this iron core. .

[Function] In this invention, by passing an alternating current through the baking coil, an induced current flows through the vacuum container, and the vacuum container is baked.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

In the above-mentioned baking device for a vacuum container, an alternating current is passed through the baking coil (11).
), and the vacuum container (1) is baked.

FIG. 2 is a configuration diagram showing a second embodiment of the present invention,
In the figure, (12) is the current transformer core, (13) is the primary coil of the current transformer, (14) is the AC power supply, and (15) is the secondary coil of the current transformer as well as the bending electromagnet core (10). It is also a wound baking coil.

In the vacuum container baking device described above, an AC power source (14
) causes an alternating current to flow through the primary coil (13), a stepped-up current flows through the baking coil (15), and the H-shaped bending electromagnet core is excited by this current. As a result, an induced current flows through the vacuum container (1), and the vacuum container (1) is baked.

In addition, although the above embodiment describes the case where it is applied to an SOR device, a nuclear fusion device having an H-shaped current transformer core can also be applied to the above embodiment if the current transformer core is excited by alternating current. It has a similar effect.

[Effects of the Invention] As explained above, according to the baking device for a vacuum container of the present invention, an H-shaped iron core is provided penetrating the doughnut-shaped vacuum container, and a baking coil is wound around this iron core, and the vacuum container is heated. Since an induced current is allowed to flow through the container, baking of the vacuum container does not require a power source with a large current capacity, and there is also no need for the ceramic insulating section that is conventionally required.
