Description

The LHCb (Large Hadron Collider Beauty) experiment is a dedicated machine for precision measurement of CP (Charge Parity) violation and rare processes in heavy flavour physics. For operation during Runs III and IV at the LHC, a complete overhaul of the VELO (VErtex LOcator) was installed and commissioned in 2022. The VELO was completely redesigned replacing the original strip detector with a hybrid-pixel design using 130 nm CMOS to survive the new luminosity and radiation targets---being exposed up to $8.0 × 10^{15} MeV n_{eq}/cm^2$ by the end of Run IV. The Upgrade I VELO has now been operating at the LHC since 2022, receiving a fluence does of $\mathcal{O}(10^{15}) MeV n_{eq}/cm^2$ in its most inner regions; doubling the dataset available to analysts. New results on the operational characteristics of the Upgrade I after 3 years of operation will be presented prioritising key performance metrics. Alongside this, novel techniques for characterising radiation damage with the digital readout will be presented showcasing through life performance of the detector. These novel results will support detector development as we reach the next radiation and luminosity frontiers in high energy physics.
