A detection system and a method for detecting ions which have been separated in a time-of-flight (TOF) mass analyser 10, comprising an amplifying arrangement 20 for converting ions into packets of secondary particles and amplifying said packets, wherein the amplifying arrangement is arranged so that each packet of secondary particles produces at least a first output and a second output separated in time and so that during the delay between producing the first and second output the first output produced by a packet of secondary particles is used for modulating the second output produced by the same packet. An increased dynamic range of detection and protection of the detection system against intense ion pulses is thereby provided. The secondary particles can be electrons, secondary ions, or photons. |
