FIELD: instrument making.
SUBSTANCE: cyclic mass spectrometer of gas particles comprises a receiver of ions, three toroidal deflectors, a unit of processing of ion spectra and grounded nets is additionally equipped with an ion source, connected to a unit of spectra processing, a pushing net connected to a generator of pushing pulses, a diverting electrode, connected to a generator of diverting pulses, a generator of diverting voltage of toroidal deflectors connected to external reflecting electrodes, voltage generators are connected to a synchronisation device, toroidal deflectors are arranged one after another and provide for cyclic flight of ions. In the drift space there are levelling nets and a focusing device, which represent quadripoles or focusing rings.
EFFECT: expanded range of investigated masses with increased resolving ability.
