N2 - We demonstrate an electrostatic surface guiding for cold polar molecules over a long distance of 44.5 cm, 0.85 mm above a dielectric substrate, and measure the transverse distribution of the guided supersonic D2O/CH3Br beam and its longitudinal velocity one. Also, we study the dependence of the relative guiding efficiency and the transverse temperature of the guided molecular beam on the guiding voltage, and show that the absolute guiding efficiencies from the Monte Carlo simulation and theoretical calculation multiplied by 3 are about equal to the measured relative one.
