Kill event optimization

A sexed semen system comprising:

• a detection laser capable of exciting a sperm cell;
• a first detection laser lens that steers a detection pulse emitted by the detection laser into a sample flow, wherein the detection pulse is capable of illuminating the sperm cell within the sample flow;
• a fluorescent dye that bounds DNA of the cell and produces a fluorescent emission event;
• a second detection laser lens that directs the fluorescent emission event onto a surface of a fluorescence detector;
• a computer processing unit for determining the sex of the sperm cell based on an output of the fluorescence detector;
• an analog to digital converter (ADC) which converts an analog voltage output signal from the fluorescence detector into a digital output signal;
• an ADC state tracker machine which monitors a raw ADC value of the analog voltage output signal to determine if a multi-cell fluorescent event has occurred, and if so, to classify each sperm cell as desirable or undesirable;
• and
• a kill laser for destroying an undesirable sperm cell.
