Spectral characteristics of the p(+)-side of a two-sided microstrip detecto
r were studied with the help of gamma- and beta-rays from Am-241 and Sr-90
radioactive sources. For minimally ionizing particles (MIP) the measured si
gnal-to-noise ratio was 25, It was shown that for collecting the informatio
n from strip detectors one can use an OLA amplifier developed for detectors
with a small self-capacitance.
