“…Another important application within the context of gas discharges is in elementary particle/ionizing radiation detection, where alcohol vapours and other hydrocarbon gases are used as quenchers [16][17][18][19]. In some cases, alcohols are also applied to suppress aging of detectors [20].…”

The results covered in this paper provide breakdown data represented by Paschen curves for methanol, isopropanol and n-butanol, along with the corresponding axial profiles of emission in Townsend regime of the discharge and including the optical emission spectra. Paschen curves were recorded in the range of pd (pressure x electrode gap) from 0.10 to 3.00 Torr cm. The optical emission spectra (OES) are recorded for wavelength range from 300 to 900 nm, for discharges in all studied alcohols. The recorded spectra enabled identification of species that participate in these discharges. All three alcohols exhibit emission from excited radicals OH (at 306.4 nm), CH (at 431.2 nm) and Hα (at 656.4 nm) produced mostly in dissociative excitation by electrons. Recorded profiles of emission enabled us to identify conditions where processes induced by heavy particles (ions and fast neutrals) are dominant in inducing emission from the discharge.
