Abstract

The anglar dependence of emitted NQR signal intensity from a polycrystalline hexamethylenetetramine has been investigated. Measurement from the radial direction reveals that the NQR signal from a long column sample showed a very inhomogeneous radiation pattern which has strong signal along the direction of the excitation and few along the perpendicular direction from the excitation axis. A series of measurement by a receiver set face to face to the sample at every 10° from 0° to 350° from the excitation direction revealed that the signal intensity measured has a trigonometric divergence. This is useful to design an antenna coil of a landmine detector to get strong NQR signal remotely.
