Editing LHCb experiment (section)

=== LHCb upgrade (2019–2021) ===
At the end of 2018, the LHC was shut down for upgrades, with a restart currently planned for early 2022. For the LHCb detector, almost all subdetectors are to be modernised or replaced.<ref>{{Cite web|title=Transforming LHCb: What's in store for the next two years?|url=https://home.cern/news/news/experiments/transforming-lhcb-whats-store-next-two-years|access-date=2021-03-21|website=CERN|language=en}}</ref> It will get a fully new tracking system composed of a modernised vertex locator, upstream tracker (UT) and scintillator fibre tracker (SciFi). The RICH detectors will also be updated, as well as the whole detector electronics. However, the most important change is the switch to the fully software trigger of the experiment, which means that every recorded collision will be analysed by sophisticated software programmes without an intermediate hardware filtering step (which was found to be a bottleneck in the past).<ref>{{Cite web|title=Allen initiative – supported by CERN openlab – key to LHCb trigger upgrade|url=https://home.cern/news/news/computing/allen-initiative-supported-cern-openlab-key-lhcb-trigger-upgrade|access-date=2021-03-21|website=CERN|language=en}}</ref>
