The LHCb VELO Upgrade I is a hybrid pixel vertex detector based on the VELOPix ASIC, a development from the Medipix/Timepix family, and uses CO2 cooling in a microchannel substrate. The sensors will be operated in vacuum and only 5mm from the LHC beam. The VELO Upgrade I starts operation in 2021.
 
The LHCb Upgrade II was recently approved by CERN to proceed to a framework Technical Design Report. The concept foresees a 4D VELO vertex detector with high spatial and timing performance and a large scale tracker based on radiation hard MAPS. A consolidation Upgrade will occur in ~2025 (LHC long shutdown 3, LS3) and full installation of Upgrade II around the end of the decade (LS4).
 
We have an opening in Manchester to work initially on the LHCb VELO module production and then on the VELO commissioning.

The deadline for applications is the 25th of February.
 
This post is currently funded until the end of the Upgrade I construction project,  with an opportunity to extend to R&D for Upgrade Ib/II silicon detectors (VELO and HV-MAPS mighty tracker).  The group has plays a leading role in LHCb Upgrade I and Upgrade II.
