Analysis of lunar samples returned by the US Apollo missions revealed that the lunar highlands consist of anorthosite, plagioclase, pyroxene, and olivine; also, the lunar maria are composed of materials such as basalt and ilmenite. More recently, the remote sensing approach has enabled reduction of the time required to investigate the entire lunar surface, compared to the approach of returning samples. Moreover, remote sensing has also made it possible to determine the existence of specific minerals and to examine wide areas. In this paper, an investigation was performed on the reflectance distribution and its trend. The results were applied to the example of the double ray stretched in parallel lines from the Tycho crater to the third-quadrant of Mare Nubium. Basic research and background information for the investigation of lunar surface characteristics is also presented. For this research, resources aboard the SELenological and ENgineering Explorer (SELENE), a Japanese lunar probe, were used. These included the Multiband Imager (MI) in the Lunar Imager / Spectrometer (LISM). The data of these instruments were edited through the toolkit, an image editing and analysis tool, Exelis Visual Information Solution (ENVI).
The second phase of the Advanced Mo-based Rare process
Experiment (AMoRE-II) searches for a neutrino-less double-beta decay
of 100Mo. A background level in the region of interest of
3034 ± 10 keV is required to be lower than 10-4 count/(keV
kg year). Neutrons can generate background signals by gamma-ray
emitting reactions with AMoRE-II detector materials. Thermal neutron
shields will be installed inside and outside the lead shield to
reduce the neutron flux in the shielding system. The background
radioactivity of the inner thermal neutron shield must be low
because AMoRE-II requires a low background level. A thermal neutron
shield with a high shielding efficiency and low radioactivity was
produced by using boric acid powder and silicone rubber. The
shielding efficiency was tested to be
{99.2 ± 0.25(stat)-0.53
+0.47(syst)}%, and
the radioactivities of 40K, 226Ra, 228Ac, and
228Th were measured to be < 9.2 at 90% C.L., 14.2 ± 1.5,
< 1.6 at 90% C.L., and 2.83 ± 0.80 mBq/kg, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
