The second stage of the "BTN-Neutron" experiment has begun on the ISS

The second stage of the "BTN-Neutron" experiment has started on the Russian segment of the International Space Station. This was reported by the press services of Roscosmos and the Space Research Institute of the Russian Academy of Sciences.

Since 2007, the BTN-M1 equipment has been recording neutrons and gamma radiation on the outer surface of the Zvezda service module. Now it has been supplemented by new BTN-M2 equipment installed inside the Nauka multipurpose laboratory module. The installation and connection of this equipment to the ISS on-board systems was successfully carried out by Roscosmos cosmonauts Alexey Ovchinin and Ivan Wagner during the 72nd long-term expedition.

With the advent of BTN-M2, the station has the ability to compare data on the neutron flux obtained in outer space with data collected inside the station, protected from external influences. The experiment will also expand the possibilities for gamma spectrometry of the radiation background and registration of neutrons and gamma rays with the highest possible time resolution.
