Beschreibungen/Notizen

• [...]making a mixture of explosives with other materials (such as the plasticizers) does not change the NQR spectrum. Furthermore, the NQR signal amplitude is proportional only to the amount of explosive present, and does not depend on the spacial distribution of explosive in the detected volume. Magnetic oscillation which are detected in NQR or low-field NMR are much weaker (usually several orders of magnitude) than the parasitic effect produced by external sources. [...]the special methods to mitigate the influence of external sources of radiofrequency interference have to be applied. For that, researchers are working for novel ultra-sensitive sensors for NQR detection, such as atomic magnetometer, SQUID-based or GMR-HTS hybrid probes, etc. [...]for development of NQR/NMR detection technique, one has to increase the sensitivity of 14N NQR, to develop approaches immune to RFI and acoustic ringing and to develop new approaches for detection of liquid substances by low-field NMR.
