'Meanwhile, FREND [Fine Resolution Epithermal Neutron
Detector] continued to collect more on the flow of neutrons from the surface," the ESA said.
and Mizera, J.: 2005, Possibilities of the short-term thermal and epithermal neutron
activation for analysis of macromycetes (mushrooms).
There is a dearth of information on the order of magnitude of phases like [[phi].sub.M1.sup.s] and [[phi].sub.E1.sup.p] for epithermal neutron
capture in medium-to-heavy nuclei.
"Sensors and instruments on the surface platform will also be used to study the subsurface water distribution at the landing site, to investigate the exchange of volatiles between the atmosphere and the surface, to monitor the radiation environment and compare it with measurements made with the radiation dosimeter on the FREND [Fine Resolution Epithermal Neutron
Detector] instrument (on the ExoMars 2016 Trace Gas Orbiter), and to carry out geophysical investigations of the planet's internal structure."
Tenders are invited for Fabrication and supply ofthermal and epithermal Neutron
shielding material as per attached specification.
