Description

As part of R&D studies related to dark matter searches, we have designed, built and operating new, small-scale dual-phase xenon TPC at the University of Zurich. Detector performance is comparable to the state-of-the-art xenon-based detectors, and the experimental goal is to conduct signal yield measurements for low-energy neutron interactions.
In this contribution I will describe detector with associated equipment, introduce the data analysis and the pulse identification algorithm, and present results from the calibration runs and first measurements with a neutron generator. In particular, I will show systematic measurements of such fundamental parameters as electron drift velocity and nuclear/electronic recoil discrimination at various electric fields, comparing these to literature values.
