The LHCb Upgrade II aims to maximize the potential for heavy flavor physics at high luminosity-LHC. The Vertex Locator (VELO) plays a crucial role in this task due to its outstanding tracking and vertexing abilities. However, during Run 5 and 6, the detector will face challenges such as increased data rate, pile-up, and radiation damage. To maintain the same vertex reconstruction efficiency, timing and new sensor and ASIC technologies are discussed. Additionally, possible new detector layouts adapted to expected conditions and their impact on RF-foil and vacuum tank geometries are explored.
The LHCb Upgrade II aims at maximizing the potential for heavy flavour physics at high luminosity-LHC. The Vertex Locator (VELO) plays an important role in this task due to its excellent tracking and vertexing abilities. During Run 5 and 6, the detector will undergo through a substantial increase in data rate, pile-up and radiation damage. To achieve the same vertex reconstruction efficiency as the current Upgrade I detector, the introduction of timing and its possible implementations are discussed. Additional requirements for new sensor and ASIC technologies, introduced to cope with increased radiation damage, data rate and timing, are also presented. Finally, possible new detector layouts, adapted to expected conditions, are discussed and their impact on the RF-foil and vacuum tank geometries are treated.
