Description
The ATLAS ITk outer endcap bare half ring are made of carbon fiber and carbon foam in order to achieve a low mass detector with very good thermal performance. The supports are cooled with CO2 flowing in a titanium pipe, placed between the two carbon foam half-sandwiches composing the local support. A qualification procedure was developed to verify these supports at their base stage (i.e. before placing electronics and sensors). This first quality control step is crucial for the following assembly steps. This work presents the procedure developed and agreed between Italy and UK
A special focus is given to the thermal control system which allows to verify any detect any minor defect without the use of any heater and/or thermal contact. The measurement is indeed done by mean of a infrared thermography and this contactless solution is non-damaging for the subject under study.
