Resistive Plate Chambers (RPCs) are essential active media of large-scale
experiments as part of the muon systems and (semi-)digital hadron calorimeters.
Among the several outstanding issues associated with the RPCs, the loss of
efficiency for the detection of particles when subjected to high particle
fluxes, and the limitations associated with the common RPC gases can be listed.
In order to address the latter issue, we developed novel RPC designs with
special anode plates coated with high secondary electron emission yield
materials such as Al2βO3β and TiO2β. The proof of principle was obtained
for various designs and is in progress for the rest. The idea was initiated
following the achievements on the development of the novel 1-glass RPCs.
Here we report on the construction of various different RPC designs, and
their performance measurements in laboratory tests and with particle beams; and
discuss the future test plans
