Abstract: | A low-energy electronic recoil calibration of
XENON1T, a dual-phase xenon time projection chamber,
with an internal 37Ar source was performed. This calibration
source features a 35-day half-life and provides two monoenergetic
lines at 2.82 keV and 0.27 keV. The photon yield
and electron yield at 2.82 keVare measured to be (32.3±0.3)
photons/keV and (40.6 ± 0.5) electrons/keV, respectively, in
agreement with other measurements and with NEST predictions.
The electron yield at 0.27 keVis alsomeasured and it is
(68.0+6.3
−3.7) electrons/keV. The 37Ar calibration confirms that
the detector is well-understood in the energy region close to
the detection threshold, with the 2.82 keV line reconstructed
at (2.83 ± 0.02) keV, which further validates the model used
to interpret the low-energy electronic recoil excess previously
reported by XENON1T. The ability to efficiently remove
argon with cryogenic distillation after the calibration proves
that 37Ar can be considered as a regular calibration source
for multi-tonne xenon detectors. |
