input loop sensitivity to electric fields
Si strip detectors are read out using a charge sensitive amplifier configuration.
Essentially we have an op amp with high gain and bandwidth which changes
its output voltage in response to current flowing into its negative input
terminal. This output voltage is fed back to the negative input terminal
via the feedback capacitor giving a negative feedback current which compensates
the current which is coming in from the detector. If the detector is AC
coupled as in the Atlas strip detectors then no DC curent will flow into
the amplifier input and the output voltage of the amplifier will stay fixed.
If now a charged particle passes through the detector it will create electron-
hole pairs which drift in the electric field in the silicon. This charge
movement in the field then produces a current pulse proportional to the
distance moved and the number of electron hole pairs with a
time structure determined by the drift time of the electrons and holes,
and the field geometry. .
