Speaker
Description
The presentation will deal with the numerous irradiation tests performed before the construction of
the ATLAS Big-Wheels (BW) TGC’s, as well as irradiation tests performed before the construction of
the New Small Wheel (NSW) sTGC’s. The results achieved by following the charge deposited by MIP’s
in each individual detector plane after 11 years of operation will be shown. A presentation will be
followed by explaining the source of issues that have developed with time, that are mainly related to
either chemical effects (independent of radiation) and construction issues, where not always full care
was taken during the detector assembly. The conclusions will emphasize that not only irradiation is
important in the long term behavior of a wire chamber, but that every detail counts.
