The HERSCHEL detector consists of a set scintillating counters, designed to increase the coverage LHCb experiment in high-rapidity regions on either side main spectrometer. new improves capabilities for studies diffractive interactions, most notably Central Exclusive Production. In this paper construction, installation, commissioning, and performance are presented.
The LHCb VELO Upgrade I, currently being installed for the 2022 start of LHC Run 3, uses silicon microchannel coolers with internally circulating bi-phase \cotwo thermal control hybrid pixel modules operating in vacuum. This is largest scale application this technology to date. Production was completed July 2019 and assembly into cooling structures September 2021. paper describes R\&D path supporting production motivation design choices. have excellent peformance, low uniform mass, no...
