Description of the Related Art JAERI-M94-072, Japan Atomic Energy Research Institute, March, 1994, p.06, a cesium introduction device for introducing cesium into an ion generator of an N-NBI device in order to improve generation efficiency. Is disclosed. This cesium introduction device vaporizes cesium in a reservoir tank outside the ion generation unit, and introduces the vapor into a high vacuum ion generation unit.

° C metal, but the pressure of the ion generation unit is 10 -5 to 10
-3 Pa high vacuum, saturated steam temperature is about 180 ℃
become. Since this cesium is consumed in the ion generating section, it is desired that the cesium introducing device introduces a certain amount commensurate with the consumption amount. In addition, cesium liquefies below the saturation temperature and liquefies, blocking the inside of the system and stopping the flow of cesium vapor. Therefore, care must be taken to keep the inside of the system below the saturation temperature.

By heating the reservoir tank, the cesium inside is vaporized, and by heating the valve and the inlet pipe, the vapor is prevented from being liquefied on the way.

統が閉塞することが発生した。In the above-mentioned prior art, there was a problem that the system of the cesium introducing device was blocked and cesium vapor did not flow. That is, in the conventional example, in the valve, particularly, the valve b which is a pneumatic drive valve, a low-temperature portion is locally formed due to the complexity of the structure, and cesium vapor condenses on this portion, and the system is blocked.

が難しく、一様に加熱・保温することができない。The reason why a low-temperature portion is easily formed locally in a valve, particularly in the valve 2 which is a pneumatic drive valve, will be described below.
(1) Due to the presence of the slide portion and the seal portion, the temperature and temperature of the component members cannot be too high due to the material and structure of the components. (2) There is a portion where the heater and the heat insulating material cannot be wound due to the opening / closing operation. (3) Since the heat capacity is larger than that of the pipe or the reservoir tank, it takes time to raise the temperature to the inside. (4) Since the structure is complicated as compared with the piping and the reservoir tank, it is difficult to wind the heater and cover the heat insulating material at equal intervals, and it is not possible to uniformly heat and keep the temperature.
