Description
Neutron veto detector based on liquid scintillator containing hydrogen atoms is an integral part of any underground experiment for dark matter search. So far, a flammable mixture of liquid hydrocarbons was used as a liquid scintillator. A safe alternative would be a liquid scintillator based on liquid argon doped with methane. In this work, we have studied the primary scintillations in pure liquid argon and its mixtures with methane, the CH4 content varying from 100 ppm to 10 %. The primary scintillations in these mixtures have for the first time been observed in the visible and NIR range and their relative light yields have been measured as function of the CH4 content.
