Квадрупольный фильтр масс с малой низкочастотной временной гармоникой электрического поля
Upper stability island created by auxiliary RF voltage with small amplitude and low frequency ν = ω/Ω = 1/10 is investigated. The possibility of operation of quadrupole mass fi lter with high transmission 50 % and high resolution about R0.1 = 3000 is demonstrated. Phase shift synchronization, ion cooling by buffer gas in RF quadrupole, and time fl ight through fringing fi eld optimization are required for achievement of such parameters.
