Measurements were made of scintillation light yield of alpha particles from the 222Rn decay chain within the DarkSide-50 liquid argon time projection chamber. The light yield was found to increase as the applied electric field increased, with alphas in a 200 V/cm electric field exhibiting a ∼2% increase in light yield compared to alphas in no field.

Effect of an electric field on luminescence quenching in liquid argon.

The increase in scintillation was not associated with an observable decrease in charge collected and it may be due to a decrease of quenching in the track core of the incident particle.
