A «TFC» readout supervision module responsible for generating necessary information and commands, see the LHCb Trigger and Online TDR and «ODIN».
A small collection of files passed along with your job. The sandboxes are stored on the DIRAC server and removed after a limited time. The files they contain must be small.
Former "default" Linux operating system at CERN (SLC6 default operating system on lxplus until end of 2018).
Large area tracking detector installed for the Upgrade I of the LHCb detector, located between the magnet and the downstream «PID» detectors. Successor of the «OT»/«IT» tracking system. Consists of 3 stations with 4 layers in a «x-u-v-x configuration:XUVX» each.
A service at a grid site that stores data. For example: CERN-USER, GRIDKA_MC-DST.
A computing centre hosting grid computing services. For example: IN2P3-LAPP.
The System for Measuring the Overlap with Gas is a gas injection system designed to increase the pressure inside the LHCb «VELO» beam vacuum.
Only noble gases are injected. The gas spreads out +/- 20 m around the nominal proton-proton interaction point
and the pressure is approximately
A multiple interface board that connects frontend and backend readout electronics of the subdetector to the «S-ODIN:S_ODIN» with a set of 3.2 Gb/s high-speed bidirectional optical links, see the LHCb Trigger and Online TDR.
The SPD consists of scintillating pads and is placed before the «PS». The joint purpose of the SPD and PS is to reduce the background for the «L0» electron trigger. The SPD, in conjunction with the «ECAL», helps distinguish between electrons and neutral particles like photons and neutral pions.
A term that collectively refers to the «TT» and «IT».
One week introduction course into computer usage at LHCb for young students. With no prerequisites on Linux usage, teaching basic survival skills including Grid usage and ntuple production. You can find the online version here.
