Emerging technologies: 4a) Cooling and cryogenics
Oral
Since 2000, a few particle physics detectors have been using evaporative Carbon Dioxide (CO2) for their low temperature cooling systems, showing exceptional performances and stability in their full range of operation. The excellent physical, thermal and fluid dynamic properties of CO2, coupled to its radiation hardness, make it a very interesting option for the cooling systems of the next...

The LHCb Vertex Detector (VELO) will be upgraded in 2018 to a lightweight, pixel detector capable of 40 MHz readout and operation in very close proximity to the LHC beams. The thermal management of the system will be provided by evaporative CO2 circulating in microchannels embedded within thin silicon plates. This solution has been selected due to the excellent thermal efficiency, the...

CO2 cooling has become a very interesting technology for current and future tracking particle detectors. A key advantage of using CO2 as refrigerant is the high heat transfer capability allowing a significant material budget saving, which is a critical element in state of the art detector technologies.
At CERN new CO2 cooling system has been constructed to serve for new ATLAS Insertable...

As part of the LHCb Phase-II upgrade programme, the existing downstream tracking
systems will be replaced by a new scintillating fibre tracker read out by multi-channel
silicon photomultipliers (SiPM). To ensure high tracking performance over the entire
experiment's lifetime, the SiPMs will be operated at sub-zero temperatures, down to -40ºC.
This presentation outlines the proposed...

The NA62 collaboration will pioneer the use of on-detector microfluidic cooling systems with the implementation of silicon microchannel plates in the GigaTracKer (GTK) pixel detectors in the fall of 2014.
The cooling plates consist of 130 µm silicon substrates in which 150 microchannels are embedded. They have a rectangular cross-section of 70 x 200 µm and they cover an area of 45 x 60 mm...

The Cryogenic Underground Observatory for Rare Events (CUORE) is a 1-ton scale bolometric experiment. The CUORE detector is an array of 988 TeO2 crystals arranged in a cylindrical compact and granular structure of 19 towers. This will be by far the largest bolometric mass ever operated. These detectors will need a base temperature around 10 mK in order to meet the performance specifications....
