ABSTRACT:
An ion beam supplied from a source is modulated so the ions at a constant flux is deflected by different amounts during two different types of deflection time periods according to a binary sequence, in order to encode the ion beam with phase information of the sequence. The binary sequence is such that ions released during two consecutive time periods of the same type overlap before reaching a detector, thereby increasing the duty cycle. The detector output signal is demodulated using the phase information of the binary sequence to recover an ion mass spectrum.
