The Zero Degree Calorimeter (ZDC) is integral part of the CMS experiment, especially, for heavy ion studies. The design of the ZDC includes two independent calorimeter sections: an electromagnetic section and a hadronic section. Sampling calorimeters using tungsten and quartz fibers have been chosen for the energy measurements. An overview of the ZDC is presented along with a current status of ...

Gaseous detectors have been used in sampling calorimeters for several years and still remain an attractive option for future collider experiments. The use of Micromegas chambers as active elements of a hadronic calorimeter was proposed a few years ago and stirred up exciting developments of this technology. Basic building blocks of large size chambers acting as signal generating and processing ...

Abstract. The calorimeter system of the LHCb experiment comprises in front to the electromagnetic and hadronic calorimeters a double detector, aimed at tagging the electric charge and the electromagnetic nature of the calorimeter clusters for the first level of trigger. It consists of two planes of scintillating pads separated by a 2.5 radiation lengths lead sheet. The first scintillating plane...

During 2003 test beam session for ATLAS Tile Calorimeter a monitoring program has been developed to ease the setup of correct running condition and the assessment of data quality. The program has been built using the Online Software services provided by the ATLAS Online Software group. The first part of this note contains a brief overview of these services followed by the full description of Ti...

A sensitive open-type calorimeter was used to measure excess heat production during electrolysis in Li2SO4/H2O solution with Pt-anode and Pd-Ni thin film cathodes 9000 Å thick, sputtered on Al2O3 substrate. In order to estimate the actual performance and possible measurement errors during electrolysis in the calorimeter used, including heat convection, bubbling and possible H2+O2 recombination,...

Prototypes of the Fermi system have been used to read out a prototype of the Atlas hadron calorimeter in a beam test at the CERN SPS. The Fermi read-out system, using a compressor and a sampling ADC, is compared to a standard charge integrating read-out by measuring the energy resolution of the calorimeter separately with the two systems on the same events. Signal processing techniques have bee...

To make precision measurements with a CsI(Tl) calorimeter in a high luminosity environment requires that the crystals are well calibrated and continually monitored for radiation damage. This should not effect the total integrated luminosity which is particularly important for the BABAR calorimeter to enable it to make CP violation measurements in the B meson system. To achieve this goal a fibre...

The ATLAS experiment at the Large Hadron Collider (LHC) measures proton-proton collisions high energies. Within Phase-I upgrade of LHC before start Run-3 in 2022, trigger system Liquid Argon calorimeter is being prepared to cope with an increased number simultaneous collisions. In back-end this new system, LATOME boards will be responsible for computation energies deposited calorimeter. commiss...

As part of the design studies for the ATLAS first-level calorimeter trigger, we have been investigating the process of bunchcrossing identification (BCID). Various digital BCID algorithms have been investigated using software simulation. Furthermore, a demonstrator system has been constructed which performs BCID on 36 channels of trigger data. The BCID algorithms are implemented in Field-Progra...
