- Abstract
A new approach to control the linear dimensions of analytical electrophysical systems is suggested. This approach uses the lens properties of electron-optical elements with a curvilinear axis. It is shown that such an approach can be effectively applied, in particular, to synthesize ion-optical systems (IOSs) for static magnetic mass spectrometers and can be implemented owing to off-axis fundamental points, the 'poles' of an electron-optical system, introduced earlier by one of the authors. The capabilities of the new approach are demonstrated with the synthesis of the IOS of a static mass spectrometer dedicated for isotopic and chemical analysis with an increased resolution. A new IOS not only provides desired high ion-optical parameters at decreased dimensions of the mass spectrometer as a whole but also makes it possible to loosen requirements for the manufacturing accuracy of IOS main elements.
