Low energy ions can be stored in "rings" of electrostatic sector fields or in systems of electrostatic mirrors between which the ions are reflected back and forth repeatedly. Because of the long flight path in such systems they very well can be used as precision time-of-flight mass spectrometers. Th

Two electrostatic mirrors, mounted symmetrically on the same optical axis facing each other, are used to increase the time-of-flight of molecular ions produced in matrix-assisted laser desorption/ionization (MALDI). The mirrors, which are used in the non-compensating mode, are located between a MALD
## Abstract The mass resolution of a timeβofβflight (TOF) mass spectrometer is directly proportional to its total flight pathlength. Multiβturn or multiβpassage ion optical geometries are necessary to obtain fight distances of sufficient length within reasonable size limitations. We have investigat
A new type of multi-turn time-of-flight mass spectrometer was constructed, consisting of four cylindrical electric sectors and 28 electric quadrupole lenses, the size of the vacuum chamber being 60 Γ 70 Γ 20 cm. It was demonstrated that the mass resolution can be increased according to the number of
