In this section, pre amplifier and the Front End Electronics (FEE) of the
Aerogel Cerenkov counter are described. The electronics of
the Aerogel Cerenkov counter is based on the electronics of
the Ring Image Cerenkov counter (RICH), because the electronics
of the RICH was developed to measure the small signals such as
Thus, first, the details of the electronics of the RICH is
described. In this part, the pre amplifier and the integrater circuit
of the RICH FEE will be described mainly, because it can be modified
for the FEE of the Aerogel Cerenkov counter.
Next, the modification for the electronics of the
Aerogel Cerenkov counter is discussed.
