LPP scientists and technicians did all the mechanical assembly of the Barrel Electronagetic Calorimeter modules and the PMT boxes at Wayne State as well as the installation work too. At home in Dubna, they produced all the mechanical components for the PMT boxes and the end steel plates for the modules.

Count rate over the South Pole is 5-10 times lower (blue region) – doubtless water presence.
First Results: HEND has 4 signals of neutronsfrom sensors SD, MD, LD and SC/IN, and for each of them the map of orbital measurements is currently produced.
The map of MD sensor is contributed by epithermal neutrons mainly left.
This MD map is consistent with the map for epithermal neutrons from Neutron Spectrometer.
