Abstract
We report constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment. We mitigate backgrounds with strong event selections, rather than requiring a scintillation signal, leaving an effective exposure of (<math><mrow><mn>22</mn><mo>±</mo><mn>3</mn></mrow></math>) tonne day.
