It has been another busy month in the pit. The ATLAS magnet team took a significant step towards finishing work on the ATLAS detector as testing of the End Cap Toroid magnets began, but an incident during the testing process has likely only slightly damaged an end-cap calorimeter, according to an on-going investigation.

The Barrel Toroid magnet was tested under optimal conditions in November of last year. The end cap magnets make up the rest of the ATLAS toroid magnet system. Each magnet is superconducting, and so both need to be cooled to 4.2 Kelvin and maintained in a good vacuum for optimal working conditions.

“It is the last magnet being tested on ATLAS before nominal operation, so this is a major milestone,” says Arnaud Foussat, magnet engineer from CERN PH-DT1. Read more on ATLAS e-News…
