“…The only exception is the point at 13 V/cm, where in one of the two datasets the data quality was significantly poorer for unknown reasons, likely due to charge up following a HV trip. Data from the EXO-200 [36], XENON100 [37] and XENON1T [38] experiments are displayed together with the measurements of dedicated setups [27,35,[39][40][41]. The drift velocity derived using 83m Kr events are in agreement with the ones in the figure within errors.…”

“…A subset of data sets from figure 19 is employed for which the measurement temperature was clearly stated. Data at 162 K [41], 165 K [40], 167 K [36], 173.4 K and 174.4 K (this study) and 184 K [35] is used. The values for the drift velocity at each electric field are determined interpolating linearly in between the published data when necessary.…”

“…where t d is the drift time, v d is the electron drift speed and the D L is the longitudinal diffusion coefficient for the liquid. Recent measurements [39,40] obtained a diffusion constant D L ≈ 25 cm 2 /s and electron drift speed v d ≈ 1.7 mm/µs for the nominal LZ drift field, translating to…”

“…Achieving electron lifetimes 20 ms (which has been recently demonstrated at the tonne-scale with liquid phase purification [131]) would be sufficient to limit charge loss to 10% in a ktonne-scale detector at the fields above. Diffusion effects are expected to be more significant at this scale than for tonne-scale detectors, with an RMS smearing of 3.0 mm (4.2 mm) for charge drifting from the central region of a 300 t (3000 t) detector [130,132,133], which would be convolved with the initial 3-4 mm size of single cluster ββ decay events near Q ββ .…”
