Abstract:
Disclosed is a getter-mounted vacuum vessel capable of improving vacuum efficiency and supporting a getter with a simple structure. The getter-mounted vacuum vessel according to the present invention includes a body with a hollow part and a getter receiving unit which is integrated with the body, connected to the hollow part, and receives the getter so that it comes into contact with the inner wall of the body. Heat is transmitted to the body by a heating element in contact with the body. The getter is heated by the heat conducted to the body.

본 발명은 이온 펌프(sputter ion pump)의 전원 공급을 제어하는 이온 펌프 전원 제어 장치(ion pump power supply controller)에 관한 것으로 보다 자세하게는 최소 8개 이상의 고전압 출력부를 제공함과 동시에 각각의 출력을 콘트롤하고 전류를 읽을 수 있도록 하는 전원 제어 장치를 제공하는 데에 있다. 본 발명에 의한 전원 제어 장치를 사용하면 다수의 이온 펌프를 구동, 제어할 수 있으므로 경제적 손실을 줄이는데 효과가 있다.
Abstract:
A compact UHV(Ultra High Vacuum) sputter ion pump bakable at low temperature and a manufacturing method thereof are provided to lower the temperature for obtaining ultra high vacuum of 10^-11 Torr or less to 100 °C or below. A sputter ion pump includes a body(120), alloy magnets, a pair of titanium cathode plates(20,40), at least one anode cell(30), and a plurality of neodymium magnets(10,50). The surface of the body is treated into a chromic oxide layer. The neodymium magnets are disposed at two opposite sides of the magnets. The titanium cathode plates are disposed between the neodymium magnets. A plurality of cylindrical anode cells are disposed between the titanium cathode plates.
Abstract:
The present invention relates to a getter pump with an improved thermal mode which can activate a getter from the exterior of a vacuum container in which the getter is accommodated. The getter pump includes: the vacuum container forming a vacuum atmosphere; the getter disposed at a vacuum side which is the inside of the vacuum container; a heating part disposed at an atmosphere side which is the outside of the vacuum container, to supply heat to the getter to activate the getter; and a flange part interposed between the getter and the heating part to divide the vacuum side and the atmosphere side, and transferring the heat to the getter from the heating part. Therefore, the installation and replacement of the getter are easily performed by the use of an indirect heat transferring method to activate the getter at the atmosphere side, thereby increasing the performance and applicability of the product.
Abstract:
PURPOSE: An ion pump power control system and method are provided to reduce an installation space by controlling a plurality of ion pumps with one power supply unit. CONSTITUTION: A shunt resistor(402) serially connects to a high voltage supply line between each ion pump and a power source. The shunt resistor detects a low current flowing in each ion pump. A high pressure relay(412) turns on and off the drive of each ion pump by serially being connected to the shunt resistor. An individual slave board(520) is connected to the shunt resistor and the high pressure relay. A master board(580) is connected to the individual slave board and controls the individual slave board.
