✦ Synopsis

This is the tirst paper which describes the conceptual and experimental basis of a rapid scan ion cyclotron resonance (rapid scan ICR) technique for mass analyzing the ions stored in a static magnetic ion trap. At constant magnetic field strength, a continuous wave excitation frequency is rapidly scanned across the mass spectrum, and the transient response of the coherently cyclotroning ions is detected. Due to the rapid scan rate, the detected signal is greatly distorted, but cross-correlation with the si High mass resolurion and a scan rate of 66 kHz s 9 nal of a single line can be used to recover the true mass spectrum. are demonstrated. Comparisons are made between rapid scan ICR and Fourier transform ICR.
