Data Acquisition in AMS

Data Acquisition in AMS

AMS-2 Data Acquisition System collects data from over 200K analog channels corresponding to the AMS-2 subdetectors. It consists of over 300 computational nodes based on ADSP-2187L Digital Signal Processors and a Main DAQ Computer based on PPC750 Processor. The DAQ software for ADSP-2187L is designed as a sub-detector independent framework and a set of detector-dependent routines. The Main DAQ Computer provides a storage for physics data as well as interfaces to ISS/STS environments.
