TNU is specific to the inverse beta decay detection mechanism with protons . 1 TNU corresponds to 1 geoneutrino event recorded over a year-long fully efficient exposure of 10 32 free protons, which is approximately the number of free protons in a 1 kiloton liquid scintillation detector.

The primary objective of the SAS-B was to measure the spatial and energy distribution of primary galactic and extragalactic gamma radiation which energies between 20 and 300 MeV . The instrumentation consisted principally of a guard scintillation detector, an upper and a lower spark chamber, and a charged particle telescope.

In this setup, the incoming particles, comprising neutrons and photons, strike the neutron detector; this is typically a scintillation detector consisting of scintillating material, a waveguide, and a photomultiplier tube ( PMT ), and will be connected to a data acquisition ( DAQ ) system to register detection details.

It has been shown to be valuable for diagnostic inhalation studies for the evaluation of pulmonary function; for imaging the lungs; and may also be used to assess rCBF . Detection of this gas occurs via a gamma camera which is a scintillation detector consisting of a collimator, a NaI crystal, and a set of photomultiplier tubes.

The facility consists of a ground-based extensive scintillation detectors with the dimensions of 1 m ?1 m ?0.05 m . 9 central detector stations contain an additional small scintillator with dimensions 0.3 m ?0.3 m ?0.05 m for high particle density ( much greater than 100 particles / m 2 ) measurements.
