“…With each FEB handling up to 128 channels, a total of 1524 FEBs are required, distributed among 58 FE crates mounted on the various cryostats. All of the on-detector FE electronics have been built to withstand the high levels of radiation [8,9] which result from the collisions of the intense LHC beams. The FEBs sample the LAr calorimeter signals at the LHC bunch crossing frequency of 40 MHz and store the samples during the latency of the ATLAS L1 trigger system.…”

“…Numerical precision |E| ≤ 2 13 MeV = 8192 MeV ∆E ≤ 2 0 MeV = 1 MeV 2 13 < |E| ≤ 2 16 MeV = 65536 MeV ∆E ≤ 2 3 MeV = 8 MeV 2 16 < |E| ≤ 2 19 MeV = 524288 MeV ∆E ≤ 2 6 MeV = 64 MeV 2 19 MeV < |E| ∆E ≤ 2 9 MeV = 512 MeV and therefore the precision, is energy-dependent (as shown in table 3) but always much lower than the calorimeter energy resolution, to avoid making a significant contribution to the overall energy uncertainty. Given the definition of Q, its numerical precision is proportional to √ Q.…”

The ATLAS detector has been designed for operation at the Large Hadron Collider at CERN. ATLAS includes electromagnetic and hadronic liquid argon calorimeters, with almost 200,000 channels of data that must be sampled at the LHC bunch crossing frequency of 40 MHz. The calorimeter electronics calibration and readout are performed by custom electronics developed specifically for these purposes. This paper describes the system performance of the ATLAS liquid argon calibration and readout electronics, including noise, energy and time resolution, and long term stability, with data taken mainly from full-system calibration runs performed after installation of the system in the ATLAS detector hall at CERN.

Radiation qualification of the front-end electronics for the readout of the ATLAS liquid argon calorimeters

et al. 2008

View full text Add to dashboard Cite

The ATLAS detector has been built to study the reactions produced by the Large Hadron Collider (LHC). ATLAS includes a system of liquid argon calorimeters for energy measurements. The electronics for amplifying, shaping, sampling, pipelining, and digitizing the calorimeter signals is implemented on a set of front-end electronic boards. The front-end boards are installed in crates mounted between the calorimeters, where they will be subjected to significant levels of radiation during LHC operation. As a result, all components used on the front-end boards had to be subjected to an extensive set of radiation qualification tests. This paper describes radiationtolerant designs, radiation testing, and radiation qualification of the front-end readout system for the ATLAS liquid argon calorimeters.
