  In recent years important progress in micropattern gaseous detectors has been
achieved in the use of resistive material to build compact spark-protected
devices. The novel idea presented here consists of the polarisation of WELL
structures using only resistive coating. This allows a new device to be built
with an architecture based on a stack of several coupled layers where drift and
WELL multiplication stages alternate in the structure. The signals from each
multiplication stage can be read out from any external readout boards through
the capacitive couplings. Each layer provides a signal with a gain of
10^4-10^5. The main advantage of this new device is the dramatic improvement of
the timing provided by the competition of the ionisation processes in the
different drift regions, which can be exploited for fast timing at the high
luminosity accelerators (e.g. HL-LHC upgrade) as well as far applications like
medical imaging.
