Performance of RPCs and diamond detectors using a new very fast low noise preamplifier

The new high energy high luminosity experiments require an improvement in 
\nboth the counting rate and the space resolution for the detectors. This improvement can be 
\nachieved by reducing the charge per count, however this implies a need for a better signal to 
\nnoise ratio in the signal processing. In this article we will show the performances of diamond 
\ndetectors and RPCs using a new preamplifier with low noise (500–1000 electrons RMS), 
\nfast shaping (about 10 ns) and large input capacitance.
