✦ Synopsis

The Trigger and Data Acquisition System of the ATLAS experiment at CERN has undergone a series of design and prototyping phases, with the aim of studying different architectural and technological choices suited to sustaining the very high event rate and data size of this experiment: up to 100 kHz Level 1 trigger accept rate, with events of the order of 2 MB.

The DAQIEF-1 project, a vertical slice of the Data AcQuisition and Event Filter, is one of these prototypes. After the completion of its development and implementation, this prototype was reengineered for exploitation as a DAQ system for the ATLAS detectors in testing and calibration phase. During summer 2002 DAQ/EF-1 has been successfully integrated with several detectors. This paper presents an overview of DAQ/EF-1, the implementation of a PC based setup that has been prepared for the combined testbeam of the Pixel, the tile calorimeter and the MDT detectors, and the usage of the Event Filter during data taking.
