A working, VME-based, 106 MHz FADC data acquisition system for the tracking detectors at D0

A data acquisition system for the tracking detectors of the D0 Colliding Detector has been built and is operational, taking cosmic ray data. It is composed of 8200 channels of 1-6-MHz 8-b flash analog to digital converters (FADCs). These are configured as sixteen channels per FADC module, up to sixteen FADC modules per crate, and a total of thirty-six 9U VME crates. A crate controller module, the control system interface, and a high-speed data buffer/driver complete the FADC crate. Design and operations details are described. >
