Abstract
Abstract
The ability of free electrons to drift long distances at
high velocities in pure liquid argon under an applied electric field
has been exploited for the past forty years to implement detectors
with increasingly larger volumes for high energy physics research.
The attachment of free electrons to impurities in the LAr is an
important limit on the free instrumented volume of these extremely
large detectors, and impurity concentrations as small as 100 ppt can
reduce their resolution and efficiency. In this paper, we summarize
the electron attachment rate constants as a function of the applied
electric field, for common impurities in LArTPCs, obtained from data
in the literature. We further provide analytical functions to
parameterize the data, which are useful to compare with new
measurements, to model and analyze the performance of existing
detectors, and to predict the performance of new detectors.
