Patent number: 8072149Abstract: A dual unbalanced indirectly heated cathode (IHC) ion chamber is disclosed. The cathodes have different surface areas, thereby affecting the amount of heat radiated by each. In the preferred embodiment, one cathode is of the size and dimension typically used for IHC ionization, as traditionally used for hot mode operation. The second cathode, preferably located on the opposite wall of the chamber, is of a smaller size. This smaller cathode is still indirectly heated by a filament, but due to its smaller size, radiates less heat into the source chamber, allowing the ion source to operate in cold mode, thereby preserving the molecular structure of the target molecules. In both modes, the unused cathode is preferably biased so as to be at the same potential as the IHC, thus allowing it to act as a repeller.Type: GrantFiled: March 31, 2008Date of Patent: December 6, 2011Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Jeong-Ha Cho, Bon-Woong Koo, Byung-Yeal Yoon, Yong-Tae Kim, Jeong-Ho Yoon
