본 발명은 기체 레이저 방전관의 방전개시전압 낮춤장치에 관한 것으로, 특히 전극이나 방전관내에 방사선 동위 원소금속관을 설치하여 그 주위에 전하군을 형성해주므로 방전개시 전압을 낮출 수 있도록 함에 주안점을 둔 것이다.The present invention relates to a device for lowering the discharge start voltage of a gas laser discharge tube, and in particular, a radioisotope metal tube is formed in the electrode or the discharge tube to form a charge group around the center, and thus the main point is to reduce the discharge start voltage.

기체 레이저는 제1도에서와 같이 방전관(1)내에 이산화탄소나 헬륨, 네온을 혼합 봉입하고 방전관의 양단에 반사경(4)(5)을 서로 마주보도록 설치해 놓은 상태에서, 양측의 캐소드 및 에노드 전극(2)(3)에 전원 장치를 이용하여 고주파 전압을 걸어 관내에서 방전시키면 양측반사경에 의해 유도방출이 일어나면서 고에너지를 가지는 레이저 광을 방사시키는 작용을 행하는 것이다. 위와같이 기체 레이저를 통해 얻어진 레이저를 에드측으로 이동시킨후 포커스마운팅 노즐을 통해 주사시키게 되면 피가공 물체의 절단을 행하는 절단가공기 또는, 감지센서와의 연동으로 매우 정밀한 물체의 복사를 행하는 레이저복사기 등 정밀산업 분야에 널리 이용되고 있다.As shown in FIG. 1, the gas laser is mixed and sealed with carbon dioxide, helium, and neon in the discharge tube 1, and the cathodes and anode electrodes on both sides are installed so that the reflectors 4 and 5 face each other at both ends of the discharge tube. When (2) and (3) are discharged in a tube by applying a high frequency voltage by using a power supply device, the induced emission is caused by both side reflecting mirrors to emit a laser energy having high energy. When the laser obtained by the gas laser is moved to the ed side and scanned through the focus mounting nozzle, the cutting machine which cuts the workpiece, or the laser copier that performs the copying of the very precise object by linking with the sensor It is widely used in industrial fields.

여기에서 상기 방전관의 초기방전 동작시에는 내부의 기체 분자들에게 매우 큰 전압을 인가하여 전자를 방출시켜야 하는 바 통상 20-30Kv의 높은 방전개시전압을 요구하기 때문에 이에 맞는 큰 용량의 고전압단을 필요로 하게 된다. 이에 따라, 큰 용량의 고전압단 설치에 따른 제반 비용의 증가는 물론이고, 초기 구동시 많은 전력을 소모하게 되는 문제점이 있었다.Here, during the initial discharge operation of the discharge tube, electrons must be discharged by applying a very large voltage to the gas molecules inside, so a high discharge start voltage of 20-30 Kv is required. Done. Accordingly, as well as an increase in overall costs due to the installation of a large capacity high voltage stage, there is a problem in that a large amount of power is consumed during initial driving.

따라서, 본 발명의 목적은 상기와 같은 종래의 문제점을 감안하여 방전관의 방전개시 동작시의 초기전압을 낮출 수 있는 장치를 제공함에 있다.Accordingly, an object of the present invention is to provide an apparatus capable of lowering an initial voltage at the time of starting operation of discharge of a discharge tube in view of the above conventional problems.

상기와 같은 목적을 달성하기 위하여, 전극이나 방전관내부의 중앙부위에 전하군 형성을 위한 방사선 동위 원소금속관을 설치하므로서, 금속관에서 발생한 β선이 기체분자를 이온화시켜 전하군을 발생시킴에 따라 보다 낮은 전압을로도 초기 방전 동작이 가능토록 한 것이다.In order to achieve the above object, by installing a radioisotope metal tube for forming a charge group at the center of the electrode or the discharge tube, the β-rays generated in the metal tube ionize gas molecules to generate a charge group. Early discharge operation is also possible with voltage.

이하에서 이를 첨부된 예시도면에 의거보다 상세히 설명코져 한다.Hereinafter will be described in more detail based on the accompanying drawings.

도면 제2도는 본 발명에 따라 구성된 방전개시 전압 낮춤 수단의 구체적인 실시예를 나타낸 것으로, β선을 발생시키는 방사선 동위 원소금속관(6)을 형성한 뒤, 이를 전극(2)에 스트립으로 감아 설치하였다. 또한, 다른 실시예로서는 제3도에서와 같이 β선 발생용 방사선 동위 원소금속관(6)을 방전관 내의 중앙부 위에 위치토록 설치하였다. 이때, 상기 방사선 동위 원소금속관은 통상 Ni 63을 사용토록한다.Figure 2 shows a specific embodiment of the discharge initiation voltage lowering means constructed in accordance with the present invention, after forming a radioisotope metal tube (6) for generating a beta line, it was wound around the electrode 2 and installed in a strip . In another embodiment, as shown in FIG. 3, the radiation isotope metal tube 6 for β-ray generation is provided so as to be positioned above the center part in the discharge tube. In this case, the radioisotope metal tube is usually Ni 63.

이상과 같이 방전관 말단의 전극 또는 방전관 내부에 방사선 동위 원소금속관(6)을 위치시킴에 따라, 상기 금속관(6)으로부터 β선이 발생하면서 방전관 내부에 충진된 기체를 이온화시켜 전하군이 형성된다. 이에 따라, 방전개시 초기전압은 상기에서 형성된 전하군내의 전자를 가속시키는데 필요한 전압만 인가하면 되므로, 도면 제4도에서와 같이 종래보다 월등히 낮은 전압치(약 15Kv)를 필요로 하게 된다.As described above, by placing the radioisotope metal tube 6 inside the electrode or the discharge tube at the end of the discharge tube, a beta line is generated from the metal tube 6 to ionize the gas filled in the discharge tube to form a charge group. Accordingly, since the discharge start initial voltage only needs to apply a voltage necessary for accelerating electrons in the above-described charge group, a voltage value (about 15 Kv) that is much lower than the conventional one is required as shown in FIG.

이상과 같이 전극이나 방전관 내부에 방사선 동위 원소금속관을 결합설치하여 그로부터 발생되는 β선으로 기체를 이온화시켜 그 주위에 전하군의 형성를 유도하여 방전개시 초기전압을 낮춰주므로서, 방전관에 고전압을 형성해주는 고전압단의 용량을 축소하여 이에 따른 설치비용을 감소시키고, 소비전력을 감소시킬수 있는 특출한 효과가 있다.As described above, the radioisotope metal tube is combined inside the electrode or the discharge tube to ionize the gas with β-rays generated therefrom to induce the formation of charge groups around it, thereby lowering the initial voltage at the start of discharge, thereby forming a high voltage in the discharge tube. By reducing the capacity of the high voltage stage, there is an outstanding effect of reducing the installation cost and power consumption.
