500 MHz transient digitizers based on GaAs CCDs

A wide-bandwidth transient digitizer based on a gallium arsenide charged-coupled device (CCD) is under development. The CCDs have 128 pixels and operate at 500 MHz. Prototype CCD digitizers which sample at 2-ns intervals for a period of 256 ns have been constructed and tested in Experiment 787 at Brookhaven National Laboratory.<
