LHCb and Silicon R&D
The LHCb experiment
LHCb is the LHC experiment dedicated to study the origin of the asymmetry that made antimatter disappearing from the Universe we observe. To this purpose, the LHCb is a forward single arm spectrometer at the heart of which is the most precise vertex detector of all the LHC experiments.
0.8 cm from the interaction point (in radius).
Highly sophisticated to spatially resolve the
Vertices, sustain the occupancy and the
VELO: the most precise
VERTEX detector system
.... and, as one can expect from a detector set to measure Beauty, it is a beautiful piece of work.
Most precise detector in LHC experiments!
Prototype for the radiation hard technology (now the golden standard for the upgrades)
First use of advanced composites (TPG for heat & ZERO-CTE layups) at CERN.
It lead to two Industry awards in the UK (Micron Semiconductors and Stevenage Circuits)

Instruments suitable for Medical physics (hadron-therapy) applications. Example of LHCbVeLo sensors as beam monitor at the Clatterbridge Centre for Oncology
LHCb module positioned in front of the extraction collimator of the Cyclotron beam.
The module was put at different distances and positions to measure the beam halo e the profile of the beam spot.
In medical Physics we have a grant for developing a novel concept of tissue equivalent phantom.
