We describe the design of the analog portion of an electronics system to process signals from the photomultiplier tubes of the ATLAS Tile Calorimeter. The system has a 16-bit dynamic range and is ...capable of measuring energy depositions in a single calorimeter cell from
∼
20
MeV
to
∼
1.3
TeV
. In order to maintain the calorimeter calibration at the 1% level the system includes a charge injection circuit and a current integrator for use with a cesium source system and with the time-averaged currents produced by the LHC. The system also provides a signal for an analog adder which produces an energy sum for each calorimeter tower. Over 10,000 channels of this system have been constructed and delivered for use.

A system to calibrate and monitor ATLAS Barrel Hadronic Calorimeter (TileCal) is under construction at CERN Laboratory. A movable radioactive source driven by a liquid flow travels through the ...calorimeter body deposing a known energy to the calorimeter cells. Extensive R&D studies have been carried out and the main system parameters are evaluated. The prototypes are currently used for quality check and inter-calibration of the TileCal modules. A distributed control system, hardware as well as corresponding on-line and off-line software is developed.
This document was prepared as part of the briefing material for the Workshop of the CERN Council Strategy Group, held in DESY Zeuthen from 2nd to 6th May 2006. It gives an overview of the physics ...issues and of the technological challenges that will shape the future of the field, and incorporates material presented and discussed during the Symposium on the European Strategy for Particle Physics, held in Orsay from 30th January to 2nd February 2006, reflecting the various opinions of the European community as recorded in written submissions to the Strategy Group and in the discussions at the Symposium.

The layout of the RPCs, used in the Argo-YBJ experiment to image with a high space-time granularity the atmospheric shower, is described in this paper. The detector has been assembled to provide both ...digital and analog informations in order to cover a wide particle density range with a time accuracy of 1
ns. The experimental results obtained operating the chambers in streamer mode at sea level with a standard gas mixture are presented.
