jsc2006e51966 (12/1/2006) --- A preflight view of BTN-M1 hardware without a cover for the BTN-Neutron experiment to be delivered to the ISS during the 23P flight.

iss067e190005 (7/20/2023) --- A view of BTN-ME Unit in the Zvezda Service Module (SM) aboard the International space Station (ISS). The Study of the Fluxes of Fast and Thermal Neutrons, focuses on the spatial and temporal distribution of neutron fluxes and spectra in near-Earth space, including during solar flares.

iss014e14541 (2/22/2007) --- A view of the BTN-ME experiment, also called BTN-Neutron experiment, attached to the Zvezda Service module as seen by the Expedition 14 crew during Russian EVA 17A. The BTN-ME experiment builds a physical model for generation of charged and neutral particles during solar flares. It also develops a physical model of neutron albedo of the earth atmosphere with regard to helio- and geophysical environment, measurement point longitude and altitude effects, time of the day and lighting conditions, atmosphere conditions. Also it develops a physical model of neutron background in the vicinity of the ISS in different flight conditions, as well as recording space gamma bursts.
