About Our Project
A new high energy physics detector named ATLAS is being built at CERN (the European Laboratory for Particle Physics) located near Geneva, Switzerland. The ATLAS detector will be impressively large, about as tall as a five story building. The entire ATLAS project currently involves 144 institutions from all around the world.
Here at the University of Illinois at Urbana-Champaign (UIUC) our job is to test photomultiplier tubes (PMTs) and to fabricate some of the sub-modules that will be used in the ATLAS Scintillating Tile Hadron Calorimeter (specifically the Extended Barrel portion of the calorimeter). The ATLAS Hadron Calorimeter will use a total of ~ 10,000 PMTs. We are testing approximately one third of those PMTs here at UIUC. As for the calorimeter sub-modules, our group is building ~ 200 of them. Each of the Extended Barrel calorimeter modules consist of 9 sub-modules. There are 64 modules in both of the Extended Barrels of the calorimeter, as well as in the Central Barrel region of the ATLAS Hadron Calorimeter.
The purpose of this Web Site is to document the progress of our work. The results of previous and current/ongoing activities are contained in the following pages.
The complete list of documents that have been put together by our group can be found here (currently being updated).

The ATLAS Detector
The sub-modules that we are fabricating are going to be part of ATLAS's Scintillating Tile Hadron Calorimeter (pictured green in the figure below). These sub-modules will be used in the Extended Barrel portions of the Scintillating Tile Hadron Calorimeter. The PMTs that we will be testing will be located in the girder section (outer radius) of the Scintillating Tile Hadron Calorimeter.
