Sumario: | The construction of the ATLAS liquid argon presamplers and accordion calorimeters are about to be completed. The first half-length barrel wheel is already installed in the cryostat and assembly of the second wheel is about to be finished. Modules for the first end-cap wheel are ready and the assembly of the first wheel is well under way. From 55000 output channels of the first barrel wheel only four channels are malfunctioning and a very small fraction of high voltage area has showed problems, ~0.15%. After a review of the construction, production, and assembly, results concerning the energy and position resolution are shown. |
