Dark-Matter Search

Dark-matter search goes deep underground in South Dakota

Almost a mile underground, in a new science facility in South Dakota, scientists of the LUX collaboration are building the world's largest dark-matter search experiment.

The can will be the core component of the Large Underground Xenon detector, or LUX, the most sensitive experiment yet to search for the elusive substance called dark matter.

Physicists will install the LUX detector deep underground to protect it from the noise of cosmic radiation. The Earth's upper atmosphere is constantly bombarded by high-energy subatomic particles—mostly protons—that originate in outer space. When these cosmic particles collide with nuclei of oxygen and nitrogen atoms in the atmosphere, they spawn showers of smaller particles. The resulting cosmic din would drown out the faint signals in ultra-sensitive detectors like LUX, if they were on the surface of the Earth. Deep underground, however, the noise abates, and the LUX detector will reside very deep—4850 feet beneath the surface—where cosmic radiation is more than a million times quieter. The water in the tank surrounding the LUX detector will further protect it from extraneous noise, such as naturally occurring radiation from the nearby rock.

Reminds me of the nutrino testing, deep underground.

I see what can be, in the reflection of the two LCD screens.
For 8 hours, pure concentration
My eyes don’t fight the office lighting, I swim until I dissolve
Sitting tight in the numbers, line by line, the resolve, the fix
Digits and reality, many transcendental mixes
Electric blood flowing, no monotonous mind corrosion.
Imagination sphere keeps me distant- Zen Implosion.

Unexpected, too close to call.
Can't be so easy...
Hesitant for greater responsibilities.

Discovery of the obvious, a memory far and distant
From a planet, a star, a different kind of astronomy
Giving me sustenance, a reason to breathe...
in this Antonym Economy.
