| In the context of modem scientific research, consider the following statements about 'IceCube', a particle detector located at South Pole, which was recently in the news : |
| 1. It is the world's largest neutrino detector, encom- passing a cubic kilometre of ice. |
| 2. It is a powerful telescope to search for dark matter. |
| 3. It is buried deep in the ice. |
| Which of the statements) given above is/are correct? |
A) Only 1
B) 2 and 3
C) 1 and 3
D) All of these
Correct Answer: D
Solution :
Exp. [d] Ice Cube is an enormous particle detector located deep in the ice at the South Pole. IceCube searches for neutrinos from the most violent astrophysical sources-events like exploding stars, gamma-ray bursts, and cataclysmic phenomena involving black holes and neutron stars. The IceCube telescope is a powerful tool to search for dark matter and could reveal the physical processes associated with the enigmatic origin of the highest energy particles in nature. In addition, exploring the background of neutrinos produced in the atmosphere, IceCube studies the neutrinos themselves; their energies far exceed those produced by accelerator beams. IceCube is the world's largest neutrino detector, encompassing a cubic kilometre of ice.
