Production and Integration of the ATLAS Insertable B-Layer
/ ATLAS IBL Collaboration
During the shutdown of the CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between the existing Pixel detector of the ATLAS experiment and a new, smaller radius beam pipe. The motivation for this new pixel layer, the Insertable B-Layer (IBL), was to maintain or improve the robustness and performance of the ATLAS tracking system, given the higher instantaneous and integrated luminosities realised following the shutdown.

Custom ultrasonic instrumentation for flow measurement and real-time binary gas analysis in the CERN ATLAS experiment

The development of custom ultrasonic instrumentation was motivated by the need for continuous real-time monitoring of possible leaks and mass flow measurement in the evaporative cooling systems of the ATLAS silicon trackers. The instruments use pairs of ultrasonic transducers transmitting sound bursts and measuring transit times in opposite directions. [...]

The cooling capabilities of C$_2$F$_6$/C$_3$F$_8$ saturated fluorocarbon blends for the ATLAS silicon tracker
/ Bates, R (Glasgow U.) ; Battistin, M (CERN) ; Berry, S (CERN) ; Bitadze, A (Glasgow U.) ; Bonneau, P (CERN) ; Bousson, N (Marseille, CPPM) ; Boyd, G (Oklahoma U.) ; Botelho-Direito, J (CERN) ; Crespo-Lopez, O (CERN) ; DiGirolamo, B (CERN) et al.
We investigate and address the performance limitations of the ATLAS silicon tracker fluorocarbon evaporative cooling system operation in the cooling circuits of the barrel silicon microstrip (SCT) sub-detector. In these circuits the minimum achievable evaporation temperatures with C(3)F(8) were higher than the original specification, and were thought to allow an insufficient safety margin against thermal runaway in detector modules subject to a radiation dose initially foreseen for 10 years operation at LHC.

The silicon tracker of the ATLAS experiment at CERN Large Hadron Collider will operate around –15°C to minimize the effects of radiation damage. The present cooling system is based on a conventional evaporative circuit, removing around 60 kW of heat dissipated by the silicon sensors and their local electronics. [...]
