The ATLAS detector has been designed for operation at CERN's Large Hadron Collider. includes a complex system of liquid argon calorimeters. This paper describes the architecture and implementation custom front end electronics developed readout
The Liquid Argon calorimeters play a central role in the ATLAS experiment. environment at LHC collider imposes challenging tasks to their read-out system. To achieve measurements of particles and trigger signals high precision, detector are processed various stages before reaching Data Acquisition system (DAQ). Signals from calorimeter cells received by front-end boards, which digitize sample incoming pulse. Read-out Driver (ROD) boards further process data rate up 75 kHz. An optimal...
The L3 experiment is one of the four experiments collecting data at LEP. For LEP phase II, second level trigger has been upgraded to a network 28 ST T9000 transputers and 2 C104 asynchronous packet switches interconnected by IEEE1355 links. It collects each crossing (22 /spl mu/s), builds-up block, processes it rejects online background events in few milliseconds. acquisition running with this system since July 1995. In data-taking environment for different hardware software implementations,...
In order to calibrate the ATLAS Liquid Argon calorimeters an accuracy better than 1%, over 16 bits dynamic range, 2 prototype boards with 128 pulse generators have been built using DMILL components. The logic of control is able enable required channels, load DAC value, delay and send calibration command. voltage distributed channels in produce μA – 200 mA precision current. current conversion uses a low-offset opamp 0.1% 5Ω resistor. Exhaustive measurements performed on this (uniformity,...
The calorimetry of the ATLAS experiment takes advantage different detectors based on liquid Argon (LAr) technology. Signals from LAr calorimeters are processed by various stages before being delivered to Data Acquisition system. calorimeter cell signals received front-end boards, which digitize a predetermined number samples bipolar waveform and sends them Read-Out Driver (ROD) boards. ROD board receives triggered data 1028 cells, determines precise energy timing processing discrete...
In order to calibrate the ATLAS Liquid Argon (LAr) calorimeters an accuracy better than 1%, over 16 bit dynamic range, chips have been designed in DMILL technology. The design and performance of a DAC, static low offset operational amplifier digital chip control calibration boards are presented. A 8 channels board using these has also realised carefully measured as this module will be replicated times final 128 board.
