Ionization quenching factors and W-values of low-energy H${}_2^{+}$ and He${}^{+}$ ions in Ar gas at low pressure measured with a bulk resistive MICROMEGAS

A. Foresi, G. Antonelli, C. Avanzini +15

The ionization quenching factor, the fraction of an ion's initial kinetic energy lost through ionization in a medium, was measured for H${}_2^{+}$ and He${}^{+}$ ions within the 2.5-5 keV…
