Prelims 2015 · Science and Technology · Question 30
In the context of modern scientific research, consider the following statements about 'IceCube', a particle detector located at South Pole, which was recently in the news:<br/>1. It is the world's largest neutrino detector, encompassing a cubic kilometre of ice.<br/>2. It is a powerful telescope to search for dark matter.<br/>3. It is buried deep in the ice.<br/><br/>Which of the statements given above is/are correct?
Answer
1, 2 and 3
1. Correct. IceCube is the world’s largest neutrino detector, instrumenting about one cubic kilometre of Antarctic ice.
2. Correct. Besides neutrino astronomy, IceCube is also used to search for dark matter, especially indirect signals from dark matter annihilation.
3. Correct. The detector’s optical sensors are buried deep in the South Pole ice, roughly 1.5 to 2.5 km below the surface.
Hence, all three statements are correct.
