Description
Large volume RPC detectors for charged particles are widely used in HEP
experiments. For such detectors monitoring gas temperature and RH working
condition is important because they both can affect the performance of the
detector.
We propose a gas RH monitoring system, specifically suited for large scale
RPC detectors, based on fiber optic technology with use of Fiber Gragg
Grating (FBG) sensors as RH probes.
The proposed technology allows to connect sensors in series along one single
optical fiber, thus greatly simplifying cable routing. Moreover, the
proposed technology neither suffers nor causes e.m. disturbances.
We have designed and successfully tested a prototype sensing device on a
fully functional RPC module. We show experimental results including long
term stability, precision and resolution.
