A long column of explosives used in an effort to achieve directivity. Types used include sausage powder, Elcord delay units, acoustic delay units, and broomstick units. An elongated charge is designed to direct the input pulse downward by matching the effective detonation velocity to the formation velocity. Its physical dimensions must be an appreciable fraction of a seismic wavelength to achieve significant directivity.
