Electron drift velocity variations in neon + 10% helium + alcohol, using spark chamber efficiency as a sensitive indicator
The disappearance probability of an electron in a gas is very sensitive to variations in transport coefficients. The efficiency of a pulsed nuclear spark chamber is a non-ideal indicator of this probability. Efficiency measurements were used to obtain spark chamber resolving times and measure drift velocity variations in (Ne+10% He)+C2H5OH in a 6.4 mm gap at NTP at E/P of .1 to 2 V/cm/mmHg and vapor pressures of 6 to 48 mmHg. The drift velocities are higher than without alcohol, and show a peak which shifts to higher E/P and velocity with increasing alcohol. The observations are related qualitatively to the reduction of electron energy by alcohol and to changes in collision cross-sections of the gas components.
