    "abstract": "The properties of thick GEM-like (TGEM) gaseous electron multipliers,\noperated at 1-740 Torr are presented. They are made of a G-10 plate, perforated\nwith millimeter-scale diameter holes. In single-multiplier elements, effective\ngains of about 104, 106, and 105 were reached at respective pressures of 1, 10\nTorr isobutane and 740 Torr Ar/5%CH4, with pulse rise-times in the few\nnanosecond scale. The high effective gain at atmospheric pressure was measured\nwith a TGEM coated with a CsI photocathode. The detector was operated in single\nand cascaded modes. Potential applications in ion and photon detection are\ndiscussed.",
