LHCb: Production, measurement and simulation of a low mass flex cable for multi gigabit/s readout for the LHCb VELO upgrade

The goal of this project is to examine the feasibility of data transmission up to ~5Gbit/s on a short (~60cm) low mass flex cable. These cables will be used for the readout of the upgraded vertex detector (VELO) of the LHCb experiment in high radiation and vacuum environment. We present a study of d...

Sumario:The goal of this project is to examine the feasibility of data transmission up to ~5Gbit/s on a short (~60cm) low mass flex cable. These cables will be used for the readout of the upgraded vertex detector (VELO) of the LHCb experiment in high radiation and vacuum environment. We present a study of different transmission line geometries, the effect of using fine pitch (400μm) connectors, the use of grounded guard traces and via holes to suppress crosstalk and the effect of the line parameters in the data transmission. Time and frequency domain measurements and simulation will be presented.
