The aim of this contribution is to present several 14N NQR approaches for a more reliable detection of the explosive TNT. The explosive TNT is from the NQR point of view very difficult to detect, one of the issues is 6 to 12 slightly nonequivalent nitrogen position in a unit cell, which is a situation not often encountered. The result of this nonequivalency is a distributed spectrum, and consequently a lower overall S/N. The majority of pulse sequences in NQR have been designed for cases, where only a single resonance line is observed, so that their efficiency for TNT is not obvious. In this contribution we present some effects related to the probe bandwidth, which is a designe parameter.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 26919463This conference precedings contain recent advances in the field of detection of explosives and illicit materials with magnetic resonance techniques. The emphasys is on nuclear quadrupole resonance and to a smaller degree also on magnetic resonance techniques. In the majority of cases the techniques are used to detect nitrogen in either solid or liquid state.
