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 Thermosiphon Cooling System of the ATLAS Experiment at the CERN Large Hadron Collider

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. [...]

A Custom Online Ultrasonic Gas Mixture Analyzer With Simultaneous Flowmetry, Developed for the Upgraded Evaporative Cooling System of the ATLAS Silicon Tracker
/ Bates, R (Glasgow U.) ; Battistin, M ; Berry, S ; Berthoud, J ; Bitadze, A ; Bonneau, P ; Botelho-Direito, J ; Bousson, N ; Boyd, G ; Bozza, G et al.
We describe a combined ultrasonic instrument for continuous gas flow measurement and simultaneous real-time binary gas mixture analysis. In the instrument, sound bursts are transmitted in opposite directions, which may be aligned with the gas flow path or at an angle to it, the latter configuration being the best adapted to high flow rates. [...]

We describe an ultrasonic instrument for continuous real-time analysis of the fractional mixture of a binary gas system. The instrument is particularly well suited to measurement of leaks of a high molecular weight gas into a system that is nominally composed of a single gas. [...]

A combined ultrasonic flow meter and binary vapour mixture analyzer for the ATLAS silicon tracker

An upgrade to the ATLAS silicon tracker cooling control system may require a change from C3F8 (octafluoro-propane) evaporative coolant to a blend containing 10-25% of C2F6 (hexafluoro-ethane). Such a change will reduce the evaporation temperature to assure thermal stability following radiation damage accumulated at full LHC luminosity. [...]

A Combined On-Line Acoustic Flowmeter and Fluorocarbon Coolant Mixture Analyzer for The ATLAS Silicon Tracker
/ Bitadze, A. (Glasgow U.) ; Bates, R. (Glasgow U.) ; Battistin, M. (CERN) ; Berry, S. (CERN) ; Bonneau, P. (CERN) ; Botelho-Direito, J. (CERN) ; DiGirolamo, B. (CERN) ; Godlewski, J. (CERN) ; Perez-Rodriguez, E. (CERN) ; Zwalinski, L. (CERN) et al.
An upgrade to the ATLAS silicon tracker cooling control system may require a change from C3F8 (octafluoro-propane) to a blend containing 10-30% of C2F6 (hexafluoro-ethane) to reduce the evaporation temperature and better protect the silicon from cumulative radiation damage with increasing LHC luminosity. Central to this upgrade is a new acoustic instrument for the real-time measurement of the C3F8/C2F6 mixture ratio and flow. [...]
