    "abstract": "The gas gain of single-wire chambers filled with isobutane, with cell\ncross-section 12x12 mm and wire diameters of 15, 25, 50 and 100 $\\mu$m, has\nbeen measured at pressures ranging 12-92 Torr. Contrary to the experience at\natmospheric pressure, at very low pressures the gas gain on thick wires is\nhigher than that on thin wires at the same applied high voltage as was recently\nshown. Bigger wire diameters should be used in wire chambers operating at very\nlow pressure if multiple scattering on wires is not an issue.",
