Description
The poster will explain the production of the 292 petals needed to build both
CMS Tracker End Caps (TECs). There will be first a description of the petal
itself integrating many components, the main ones being the silicon
modules. The organisation of the production involving 7 Institutes all over
Europe will then be explained. The assembly and testing of the petals will be
detailed next. The production rates that have been achieved will be
explained, clearly driven by the logistic aspects. The quality assurance
strategy will be detailed next, resulting in a very high petal quality. Some
overall plots will be shown like the module leakage currents, the noise
flatness, the number of flagged channels, the silicon temperature in cold,
together with some ”strip” histograms (pedestal, risetime, noise). Finally
some details about part failures will be given. The conclusion will state that
292 petals have been built and are of excellent quality. They have been
delivered to the End Caps Integration Centres in time and behave well after
integration.
