Low-Energy Nuclear Recoil Calibration of XENONnT with a $^{88}$YBe
Photoneutron Source
Characterizing low-energy (O(1keV)) nuclear recoils near the detector threshold is one of the major challenges for large direct dark matter detectors. To that end, we have successfully used a Yttrium-Beryllium photoneutron source that emits 152 keV neutrons for the calibration of the light and charge yields of the XENONnT experiment …
