Query: Estimation of the ionisation quenching factor in gases from W-value
  measurements   The effect of ionisation quenching for ions is critical for experiments
relying on the measurement of low energy recoils, such as direct Dark Matter
searches. We present ionisation quenching factor estimates over a range of
energies for protons, $\alpha$-particles, and heavier ions in H$_{2}$,
CH$_{4}$, N$_{2}$, Ar, CO$_{2}$, and C$_{3}$H$_{8}$ gases, estimated from the
respective reference W-value measurements. The resulting ionisation quenching
factors are compared with predictions from SRIM.
