Data Acquisition System



data acquisition system (DAQ) is the brain behind GLAST, as it makes the initial distinction
32bit.jpg (49053 bytes) between false signals and real gamma ray signals, and decides which of the signals should be relayed to the ground. This system collects the data from the subsystems, implements the multi-level event trigger, and provides an on-board science analysis platform to search for transients.The DAQ consists of specialized electronics and 32-bit radiation-hard processors that record and analyze the information generated by the silicon-strip detectors and the calorimeter. The DAQ will be shielded from the rigors of space-flight, such as extreme high and low temperatures as well as high energy cosmic rays, which can cause the electronics to malfunction
