Abstract: Systems or techniques are provided for clock and event synchronization. In various embodiments, a system can comprise a master clock and one or more agent clocks. In various aspects, the system can synchronize timers in the one or more agent clocks with the master clock based on a timestamp from the master clock. In various aspects, the system can adjust clock speed of the one or more agent clocks based on a comparison of a second timestamp from the master clock and times of the one or more agent clocks at the time of receiving the second timestamp.

Abstract: Ions are injected into an orbital electrostatic trap. An ejection potential is applied to an ion storage device, to cause ions stored in the ion storage device to be ejected towards the orbital electrostatic trap. Synchronous injection potentials are applied to a central electrode of the orbital electrostatic trap and a deflector electrode associated with the orbital electrostatic trap, to cause the ions ejected from the ion storage device to be captured by the electrostatic trap such that they orbit the central electrode. Application of the ejection potential and application of the synchronous injection potentials are each started at respective different times, the difference in times being selected based on desired values of mass-to-charge ratios of ions to be captured by the orbital electrostatic trap.

Abstract: A signal processing unit comprises: at least one data signal input line adapted to receive a measured data signal generated by an image current, the measured data signal comprising an added crosstalk signal induced by a source of electromagnetic disturbance; at least one disturbance signal input line adapted to receive a decoupled disturbance signal, extracted from the source of electromagnetic disturbance; an output line adapted to supply a compensated data signal; a conditioning module, to which the decoupled disturbance signal is supplied via the disturbance signal input line and which provides a compensation signal; and an adding module, to which the measured data signal and the compensation signal are provided and in which the measured data signal and the compensation signal are superposed, whereby the decoupled disturbance signal is conditioned by the conditioning module such that the compensation signal essentially corresponds to an inverted added crosstalk signal.

Abstract: There is disclosed a method for eliminating an added crosstalk signal from a measured data signal, which is generated by an image current. There is further disclosed a signal processing unit for carrying out the method. There is still further disclosed a mass spectrometer and a mass analyser comprising the signal processing unit for carrying out the method. There is yet still further disclosed a Fourier transform mass spectrometer configured to eliminate the added crosstalk signal from a measured data signal.
