    "abstract": "A self quenching streamer (SQS), or limited streamer mode has been studied in\nsingle wire chambers with cross-sections 12x12 mm and wire diameters 15, 25 and\n50 microns. Chambers were filled with either pure dimethyl ether (DME) or\nisobutane gases and irradiated with Gd-148 alpha and Fe-55 x-ray sources. Clear\ntransitions from a proportional to 100% SQS mode were observed on all three\ndiameter wires with both gases irradiated with alpha particles. Double SQS\ndischarges due to inclined tracks observed in DME gas allowed an estimation of\na streamer size along the wire of less than 1 mm. The second SQS discharge\nappears less than 1 mm from the first within about 500 ns. Charge spectra\nobtained with DME irradiated with Fe-55 x-rays might also be interpreted as a\ntransition to a SQS mode, although no direct evidence of that was seen in the\nobserved pulse shapes.",
