Ge-diode detector combined with crystal-diffraction spectrometer permits high-resolution gamma ray spectroscopy

Crystal-diffraction spectrometer, combined with a lithium-drifted Ge-diode detector, performs high-resolution gamma ray spectroscopy on the complicated neutron-capture gamma ray spectra. The system is most useful in the 1-3 MeV energy range and improves the signal to background ratio.

Ion-retarding lens improves the abundance sensitivity of tandem mass spectrometers

Ion-retarding lens which increases the abundance sensitivity of tandem magnetic-analyzer mass spectrometers measures isotopes of low abundance in mass positions adjacent to isotopes of high abundance. The lens increases the abundance sensitivity for isotopes lying farther from high abundance isotopes than the energy cutoff of the lens.

Monopole mass spectrometer with improved sensitivity and reduced background

Monopole mass spectrometer is increased by nearly an order of magnitude when a weak external magnetic field is applied so that the ion beam is deflected towards the rod. This magnetic field eliminates background noise at the low end of the mass scale.
