1. Apparatus for pulse processing and data acquisition from a plurality of detectors generating asynchronous event pulses from a single event, comprising:

  • a plurality of parallel input channels, each of which receives one of the event pulses from a respective detector;

    pulse digitization means in each channel for digitizing the event pulse received in the channel;

    a channel FIFO buffer in each channel connected to the respective pulse digitization means;

    a common data bus connected to all the FIFO buffers;

    central control means external to the channels connected to each channel for providing a synchronizing timing signal to the respective pulse digitization means in each channel in response to a start signal from at least one of the channels to synchronize pulse digitization in each channel with detection of the event by the respective detector and to digitize each pulse on each channel substantially immediately after the pulse is input on the channel;

    a bus controller connected to the data bus and to the control means for transferring correlated data from the FIFO buffers to the data bus following an actuation signal from the control means, the transferred data being correlated to the event.
