    "abstract": "We describe first results obtained with a track structure imaging system for\nmeasuring the ionisation topology of charged particles in a low-pressure gas.\nThe detection method is based on a time projection chamber (TPC) filled with\nlow-pressure triethylamine (TEA). Images of ionisation tracks of electrons,\nprotons, and heavier ions are presented and analysed.",
