A new detector concept optimizes MPGD geometry for low-cost and large-area applications while
keeping the same performance. The base element, a µRtube, is a cylindrically shaped µRWELL of
0.9 cm radius, which works as an amplification stage and readout. The external sleeve is 18 cm in
diameter and accommodates the cathode, completing a radial tubular TPC having a small internal
surface used for the readout. This geometry significantly reduces the number of electronic channels
per unit area and brings a new technological achievement with an unprecedented curvature radius
of MPDG for imaging and particle identification applications. The detection technique of the
µRtube is based on the TPC approach where time information is used to reconstruct the ionizing
particle path inside the drift volume. A report on the detector concept and its validation through a
full simulation, relative gain measurements using a radioactive source, and test beam is presented.
A preliminary spatial resolution of approximately 700 µm was achieved.
