| Description | We successfully developed the fast readout chain for the LHCb Upgrade II RICH system. Tests and characterisations of different sensors. Converged on a candidate for LS3 enhancements which will be installed in 2027. Prototyping of the final production readout board, FastRICH delivered and under rigorous testing. |
| Exploitation Route | For use by those who will install and commission LS3 enhancements. Into production cycle for LS4. |
| Sectors | Digital/Communication/Information Technologies (including Software) Electronics |
| Description | Many of the devices we design and develop in our lab at Cambridge are then shipped to CERN for rigorous testing in "test beams". We setup and test the devices using CERN's facilities and in-house expertise, along with other institute representatives with whom we collaborate. Some of the devices, e.g. picoTDC, are commercialised via CERN micro-electronics. |

| Impact | These developments allow the LHCb detector and its upgrades to run at the design performance and beyond. The electronics read out chain from photon sensor to offline signal is developed by Cambridge under this grant. We produce electronics for around 3-4 test beam runs per year, iterating and improving the design to hit grant milestones. This work will continue until the ultimate hardware upgrade of LHCb is installed (~2030s). Commercialisation of these items are routinely done under CERN microelectronics (ME) Department. |

| Description | Cambridge Particle Physics Masterclass |
| Form Of Engagement Activity | Participation in an activity, workshop or similar |
| Part Of Official Scheme? | No |
| Geographic Reach | National |
| Primary Audience | Schools |
| Results and Impact | We invite A-level physics students from across the country to participate in a one day workshop (we do two sets of about 50 each on two days) - 100 pupils in total. These events are primarily intended for those students taking A-Level modules or equivalent that include particle physics, but are also open to any physics student or teacher interested in studying or teaching the subject. The days are a mixture of short talks by research physicists and practical sessions. |
