Prospects of Dark Matter Direct Search under Deep Sea Water in India
Journal Title: Journal of Nuclear Physics, Material Sciences, Radiation and Applications - Year 2013, Vol 1, Issue 1
Abstract
There is compelling evidence from cosmological and astrophysical observations that about one quarter of the energy density of the universe can be attributed to cold dark matter (CDM), whose nature and properties are still unknown. Around the world large numbers of experiments are using different techniques of dark matter direct and indirect detections. According to their experimental requirements location of the experiment prefer to use either underground, under ice, or under sea water. In a country like India, digging underground cavern and long tunnel is not very convenient. Therefore, authors look from the other solutions of this problem preferring to use deep sea water. In this article, we discuss the pros and corns of use of deep sea water in the dark matter search.

Third Harmonic Generation of a Short Pulse Laser in a Tunnel Ionizing Plasma: Effect of Self-Defocusing
Third harmonic generation of a Gaussian short pulse laser in a tunnel ionizing plasma is investigated. A Gaussian short pulse laser propagating through a tunnel ionizing plasma generates third harmonic wave. Inhomogeneit...
Determination of the Thermal Neutron Flux by Measuring Gamma Radiations with High and Low Resolution Detectors
Thermal neutron flux (Фth) of Americium-Beryllium (Am-Be) neutron source has been measured by adopting the foil activation method. The neutrons emitted from Am-Be source are used to activate the indium-115 (115In) foil....
Jung’s Theorem Applied in Nuclear Track Methodology.
Nuclear track density provides accelerator beam imaging and diagnostic employing CR-39 passive detectors. Counting charged particles related tracks by automated reading systems depend on the accuracy of microscope field...
Radiation Induced Oxidation Reactions of Ferrous Ions: An Agent-based Model
Chemical Fricke dosimeter in the laboratory can be submitted to gamma radiation at low temperatures to study the evolution of oxidation reactions induced by radiation, a key process to understand the formation of complex...
Radon in Workplaces the Urgent Need of New Measurements and Devices.
The existing passive radon monitors, their relative calibration facilities together with the past intercomparison exercises have been mission-oriented towards radon measurements in dwellings. These monitors have been suc...
