Abstract
The Tile Calorimeter (TileCal) is the hadron calorimeter covering the central region of the ATLAS experiment alternating layers of steel and plastic scintillators. The scintillators are read-out by wavelength shifting fibers coupled to photomultiplier tubes (PMTs). The analog signals from PMTs are amplified, shaped, sampled, digitized and stored on detector until a trigger decision is received. Each stage of the signal production from scintillation light to the PMT signal reconstruction is monitored and calibrated. This contribution focuses on the TileCal calibration systems including a Cesium radioactive source, a laser and its upgrade for High Luminosity LHC, a charge injection system, and an integrator-based readout system. A summary of the latest calibration results during LHC Run 3 and a description of the new components of the laser system will be presented.
期刊介绍:
Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section.
Theoretical as well as experimental papers are accepted.
