<p>The present invention relates to an optical ioniser. The optical ioniser comprises: an X-ray tube which generates electrons on the inside of a tube, and in which the electrons are pulled by means of the potential difference of a cathode and an anode so as to produce X-rays; a first side-surface part which is positioned connected to the X-ray tube in the portion where the X-rays produced from the X-ray tube are emitted, and has a hole for emitting the X-rays; a power source unit for supplying power to the X-ray tube; and a first part and a third part positioned surrounding the outside of the X-ray tube and the power source unit in order to protect the outside of the X-ray tube and the power source unit. The first side-surface part also comprises a first frame coupling part and a second frame coupling part constituted by holes through which screws can pass, the third part is positioned surrounding the side surface of the X-ray tube and the power source unit and also comprises a third frame coupling part and a fourth frame coupling part constituted by holes through which screws can pass, and one of the screws is positioned so as to pass through the first frame coupling part and the third frame coupling part while another one of the screws is positioned so as to pass through the second frame coupling part and the fourth frame coupling part, thereby coupling the first side-surface part and the third part. This makes it possible to couple or separate the first part and the third part, enhances efficiency of assembly during production, and enhances efficiency of replacement when a defect occurs in the X-ray tube.</p> |
