Light Propagation in Liquid Argon

The propagation velocity of scintillation light in liquid argon vg at λ ∼ 128 nm wavelength, has been measured for the first time in a dedicated experimental setup at CERN. The obtained result 1/vg = 7.46 ± 0.08 ns/m, is then used to derive the value of the refractive index (n) and the Rayleigh scat...

description The propagation velocity of scintillation light in liquid argon vg at λ ∼ 128 nm wavelength, has been measured for the first time in a dedicated experimental setup at CERN. The obtained result 1/vg = 7.46 ± 0.08 ns/m, is then used to derive the value of the refractive index (n) and the Rayleigh scattering length (L) for liquid argon in the VUV region. For λ = 128 nm we found n= 1.358 ± 0.003 and L= 99.1 ± 2.3 cm. The measured values are of interest for a variety of experiments searching for rare events like neutrino and dark matter interactions. The derived quantities also represent key information for theoretical models describing the propagation of scintillation light in liquid argon.
