The Charge State of Protons with 90 and 100 keV Energies Decelerated in Hydrogen Plasma

<div>Energy losses of protons penetrating through hydrogen gas discharging plasma. (a) 100 keV proton in plasma (the initial gas pressure was about 0.81 mbar, and the voltage was 3 kV); (b) 90 keV proton in plasma (the initial gas pressure was about 1.25 mbar, and the voltage was 3 kV). The symbols represent experimental data. The solid line represents the theoretical predictions of the Bethe model with <i>Z</i><sub>eff</sub> = 1.</div>
