ATLAS trigger/DAQ RobIn prototype

Configuration Databases in the ATLAS DAQ Prototype

A prototype of the ATLAS Prototype-1 DAQ Configuration Databases, based on persistent object managers, has been developed. We give here some details of the architecture, implementation and test results. Conclusions and plans for the further work are presented.

Design and Prototype Performance of the ATLAS Pixel Detector

The ATLAS experiment at the LHC will have three barrel and two times ve disk layers of silicon pixel detectors as the innermost elements of the Inner Tracking Detector. The detector is built adopting the hybrid pixel technology in which 16 highly performant FE chips are connected to a silicon sensor by means of the bump and ip-chip technique. Owing to the high bunch crossing rate of 40 MHz at t...

First Cryogenic Testing of the ATLAS Superconducting Prototype Magnets

The superconducting magnet system of the ATLAS detector will consist of a central solenoid, two end-cap toroids and the barrel toroid made of eight coils (BT) symmetrically placed around the central axis of the detector. All these magnets will be individually tested in an experimental area prior to their final installation in the underground cavern of the LHC collider. A dedicated cryogenic tes...

Applications of CORBA in the Atlas prototype DAQ

This paper prescnts tlic cxpericnce of using the Common Object Requcst Broker Architecture (CORBA)[ I] in tlic ATLAS prototype DAQ project[2]. Many coiiiniunication links in the DAQ systcm have been dcsigned and implcmentcd using thc CORBA standard. A public domain package, callcd Inter-Language Unification (ILU)[3] has bccn used to implement C O R M based communications between DAQ componcnts ...
