  The limitation of the detection rate of standard bakelite resistive plate
chambers (RPC) used as muon detectors in the LHC experiments has prevented the
use of such detectors in the high rate regions in both CMS and ATLAS detectors.
One alternative to these detectors are RPCs made with low resistivity glass
plates ($10^{10} {\rm \Omega .cm}$), a beam test at DESY has shown that such
detectors can operate at few thousand Hz/cm$^2$ with high efficiency(> 90%)
