Measurement of electron transport in liquid argon in crossed electric and magnetic fields

We report on a measurement of excess electron drift properties in liquid argon in the presence of crossed electric and magnetic fields. The electric field strength was varied between 6 and 110 V/cm. Using a superconducting solenoid magnetic field strengths up to 5 T were achieved. The magnetic field B&oarr; oriented perpendicular to the electric field E&oarr; and the components of the drift velocity υ&oarr;_D parallel and perpendicular to the electric field were measured, from which were derived the drift mobility μ_D, Hall angle θ_H and Hall mobility μ _H. An increase of μ_H compared to μ_D in the density range of the mobility maximum is observed. The ratio μ_H/μ_D for B→0 takes a value between 2.0 and 2.5 depending on the electric field strength. The Hall angle θ_H as function of the magnetic field strength deviates from a linear behavior only in the density region showing a high mobility. The results are compared with available data
