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....
Due to the extensive power dissipation of electronics, the STS detector requires liquid cooling supply. As cooling agent 3M NOVEC 649 engineering fluid or perfluoro(2-methyl-3-pentanone) was chosen not only because it is characterized by low viscosity and radiation hardness, but also due to the extremely low global warming potential (GWP). To cool down the cooling agent, a refrigeration system...
Silicon Tracking System of the future heavy-ion CBM experiment has several distinctive features to manage the unprecedented beam-target interaction rate of up to 10 MHz. In order to maintain a material budget within 2 − 8%X0, while achieving sufficient granularity, spatial and timing precision, a novel integration approach was employed where the read-out electronics are placed outside of the...
The Mu2e experiment at Fermi National Accelerator Laboratory (Batavia, Illinois, USA) searches for the charged-lepton flavor violating neutrino-less conversion of a negative muon into an electron in the field of an aluminium nucleus. The calorimeter plays an important role to provide excellent particle identification capabilities and an online trigger filter while aiding the track...
