Abstract :
The Unix Data Acquisition System (UDAS) is a Fermilab-based prototype for online data acquisition and analysis. The system employs a shared memory approach for the storage and accessibility of the large set of data (approximately 0.5 Megasamples) it is capable of handling. It is used to analyze turn-by-turn data obtained through two beam position monitors of the Fermilab main ring. The data are digitized with a LeCroy 810 fast waveform digitizer. The system was used to obtain a continuous tune measurement in a single main ring cycle after applying a noise signal (white noise or a chirp signal) to the beam through the main ring slow dampers.<>
