title: Note: A high-efficiency multi-coincidence method designed for molecular fragmentation studies.
abstract: A high-efficiency multi-coincidence method is developed based on the hardware electronic multiple coincidence units. The multi-hit signals originating from one single detector can be selected and measured in coincidence. The performance of the method is tested by the electron impact three-body fragmentation of CO2(3+). Compared to the conventional method, the relative and absolute coincidence efficiencies of the triple-coincidence measurement are improved by about 200 and 3 times, respectively.
