Emission of single and few electrons in XENON1T and limits on light dark matter
Emission of single and few electrons in XENON1T and limits on light dark matter
Delayed single- and few-electron emissions plague dual-phase time projection chambers, limiting their potential to search for light-mass dark matter. This paper examines the origins of these events in the XENON1T experiment. Characterization of the intensity of delayed electron backgrounds shows that the resulting emissions are correlated, in time and position, …
