The Sand-Glass Gas detector is a novel position-sensitive micro-pattern gas detector. It has been manufactured using the printed circuit board technique and its structure is based on two thin kapton foils joined together. The foils are copper-clad on both sides with the strip electrodes structure engraved on each side, and with a very dense perforation of conically shaped hole pattern etched through both of them, forming the Sand-Glass shape. The two foils are in electrical contact; the outer faces form cathodes, and the inner layer becomes an anode. Due to the electric field symmetry, electrons from avalanches are collected on the central electrode of the Sand-Glass holes. This geometry may allow 2-D readout in the single gas amplification structure.
