We present a description of the CMS central hadron calorimeter. We describe the production of the 1996 CMS hadron testbeam module. We show the results of the quality control tests of the testbeam module. We present some results of the 1995 CMS hadron testbeam. The design of the CMS detector starts with the 4 T solenoidal magnet of length 13 m and inner diameter 5.9 m. The magnet determines many...

(1) The object of a bomb calorimeter is to absorb the heat released from an accurately measured amount of chemical reaction and convert it into a temperature rise which can be measured with corresponding accuracy. Questions associated with the chemical reaction are often difficult, but will not be discussed here. This paper is concerned with the purely physical questions associated with the tem...

The CMS regional calorimeter trigger system detects signatures of electrons/photons, taus, jets, and missing and total transverse energy in a deadtimeless pipelined architecture. This system contains 20 crates of custombuilt electronics. Much of the processing in this system is performed by five types of 160 MHz digital ASICs. These ASICs have been designed in the Vitesse submicron highintegrat...

dbstract. mis paper continues the description of an isothermal titration calorimeter already outlined in the previous paper. We have determined its thermal parameters and report here on the performance of the calorimeter and the method of measuring via electrical compensation of the thermal effect. We have also calculated the effective volume of the reaction vessel and the heat of stirring of t...

The physics motivations for a fine grain 1st level electron/photon trigger which exploits the properties of the CMS crystal calorimeter are briefly introduced. An implementation architecture that extends the present design of the CMS calorimeter trigger is described. We then discuss the characteristics and the requirements of the electronic circuits needed to implement the fine grained trigger ...

Thermal sensors based on thermopiles are some of the most robust and popular temperature sensing technologies across industries and research disciplines. A chip calorimeter with a 3D thermopile layout with a large sensing area and multichannel capacity has been developed, which is highly desired for many applications requiring large reaction chambers or high throughputs, such as biofilm researc...

The method of extraction of the e/h ratio for electromagnetic compartment of combined calorimeter is suggested and the non-compensation was determined. The results agree with the Monte Carlo prediction and results of the weighting method for electromagnetic compartment of combined calorimeter. The new easy method of a hadronic energy reconstruction for a combined calori-meter is also suggested....

Calorimeter-assisted track finding algorithm takes advantage of the finely segmented electromagnetic calorimeter proposed for the SiD detector concept by looking for ”MIP stubs” produced by charged particles in the calorimeter, and using them as seeds for pattern recognition in the tracker. The algorithm allows for efficient reconstruction of tracks that cannot be found using seeds provided by ...

The ATLAS detector is being built in CERN at the LHC. It is a general purpose detector that will be used for a variety of experiments, such as searching for the Higgs Boson. The electromagnetic calorimeter is a component of ATLAS responsible for measuring the energy deposited by e, e−, and γ. This paper presents a study of the resolution of the E-M calorimeter using data simulated by GEANT 4. A...

To match these requirements CHARM2 [2] has been built !as a high mass,low 2, high granularity, sampling calorimeter (total mass 692 tons). The calorimeter is made of 420 modules, each module consisting of a 3.7 m 'X 3.7 m, 4.8 cm thick, glass plate and of a plane of 352 plastic limited streamer Fubes with digital readout of the wires and analog readout of pickup strips orthogonal to the wires. ...
