Noise Characterization of the ATLAS Tile Calorimeter Readout System

نویسنده

  • Christopher J. Meyer
چکیده

It is shown that the addition of a low pass RC filter to the current ATLAS Tile Calorimeter 3-in-1 card decreases the high frequency noise. A peak in the output voltage is found for 29 Mhz input noise but is filtered out by the same low pass filter.

CALIBRATION AND MONITORING OF THE TILE HADRONIC CALORIMETER OF ATLAS WITH A 137Cs SOURCE

Monitoring and intercalibration of the ATLAS TileCal is based on a hydraulically driven gamma source system. Extensive R&D has been carried out and has led to a detailed design for the full ATLAS TileCal. A prototype system has been built and tested on the Barrel and Extended Barrel modules. The realisation of the Cs source system, results concerning its performance, comparisons with other cali...

The drawer system concept for theATLAS

One strong constraint in ATLAS is the easy and fast access to the Tile calorimeter readout without any destructive interference with the rest of the detector. Therefore the drawer system has been designed to place all PMTs and associated electronics on a movable system inside the TILECAL girders which provide both, the structural support to the individual modules and the solenoid return ux. In ...

Eeect of the Tile Calorimeter Thickness in the Atlas Barrel Calorimeter Performance

We report on the study of the eeect of the Tile calorimeter thickness in the ATLAS Barrel calorimeter performance. The reduction of the Tile Calorimeter depth by 20 cm would have severe consequences on the hadron calorimeter performance and would increase the punchtrough probability in the muon chambers placed behind the calorimeter. Cost savings are also analysed.

Installation and commissioning of the ATLAS

The cryostats of the ATLAS LAr calorimeter system are installed in the ATLAS cavern since several years. Following this, an effort to install and commission the front-end and back-end read-out electronics as well as the timing, trigger and control electronics (infrastructure, crates, and boards) has been ongoing and is finished now, in time for the cavern closure. Following cautious procedures ...

Lifetime Test for Optical Transmitters in the ATLAS Liquid Argon Calorimeter Readout System

Accelerated lifetime test has been carried out for 147 days on the custom-made optical transmitters used in the ATLAS Liquid Argon Calorimeter front-end electronics readout system. The lifetime of these optical transmitters is estimated to be greater than 200 years and exceeds the design goal for the LHC. The random failure rate has been estimated at 9.6×10 per hour at 90% confidence level.
