Abstract

Mixtures of liquid nitrogen (LN2)/liquid methane (LCH4), LCH4/liquid argon (LAr), and LAr/LN2 with various mixing ratios were produced by cooling down the mixed gases directly in a measurement cell. The liquid temperature with a vapor pressure of 1 bar varied monotonically between the boiling point of every two liquids among LN2, LAr, and LCH4. The ratio of the photoelectric current in the liquids, J_L, to the current in vacuum, J_V, was between those in two component liquids in a wide range of the electric field, E. From J_L/J_V vs. E curves, the electron mobility in the liquid mixtures was estimated
