Installation and commissioning of the ATLAS

چکیده

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 and with continuous testing-campaigns of the electronics at each step of the installation advancement, the result is a fully commissioned calorimeter with its readout and a small number of nonfunctional channels. The paper will give a general overview of the installation and refurbishment campaign of the ATLAS LAr calorimeter electronics. Different problems observed and addressed will be discussed. It will describe noise studies that have been performed and shortly review the solutions implemented to reduce noise.

Installation and Commissioning of the ATLAS LAr Readout Electronics

Abstract. The Liquid Argon Calorimeter (LAr) is a subsystem in the ATLAS experiment which is being assembled at the Large Hadron Collider (LHC) at CERN. The readout electronics system for the LAr is discussed here. The front-end of the readout will work in radiation environment. This special requirement has led to the development of a large number of rad-hard ASICs. The back-end of the readout ...

Readiness of the Atlas Experiment for First Data

The ATLAS detector is one of the experiments at the LHC that will detect high-energy proton collisions at 14 TeV. The commissioning of the detector has started already in 2005 in parallel to the detector installation and is still in progress. The data taken so far corresponds to noise runs, cosmic muon events and beam background events from single beam in September 2008. We present the current ...

The ATLAS Insertable B-Layer: from construction to operation

The ATLAS Insertable B-Layer (IBL) is a fourth layer of pixel detectors, and has been installed in May 2014 at a radius of 3.3 cm from the beam axis and between the existing Pixel detector and a new smaller radius beam-pipe. The new detector, built to cope with high radiation and occupancy, is the first large scale application of 3D detectors and CMOS 130 nm technology. The IBL detector constru...

Estimating Solar Radiation and Developing Iran’s Atlas Map of Optimum Monthly Tilt Angle (TECHNICAL NOTE)

Iran has great potential in utilizing solar energy. In order to maximize the amount of absorbed solar radiation to absorber surfaces, the surfaces should be installed at a suitable angle slope to the horizon that is discussed in this article. The calculations performed in this study was done using MATLAB software. In this study, radiation received on the ground in 31 provincial capitals of the ...

A Cosmic Ray Measurement Facility for ATLAS Muon Chambers

Monitored Drift Tube (MDT) chambers will constitute the large majority of precision detectors in the Muon Spectrometer of the ATLAS experiment at the Large Hadron Collider at CERN. For commissioning and calibration of MDT chambers, a Cosmic Ray Measurement Facility is in operation at Munich University. The objectives of this facility are to test the chambers and on-chamber electronics, to map t...
