The CMS (Compact Muon Solenoid) detector will use silicon
sensors in the harsh radiation environment of the LHC (Large
Hadron Collider) and high magnetic fields.
The drift direction of the charge carriers is aected by the
Lorentz force due to the high magnetic field. Also the resulting
radiation damage changes the properties of the drift. The CMS
silicon strip detector is read out on the p-side of the sensors,
where holes are collected, while the pixel sensors have n-side
read out, thus collecting electrons.
In this paper measurements of the Lorentz angle are reviewed.
Easy algorithms to compute the Lorentz angle are proposed.
