“MINERνA”的意思、由来-开放百科全书

The first detector module was completed in early 2006,^[1] and the first events were observed by the partially assembled detector in April 2009.^[2]^[3] Construction was completed in January, and the detector was installed in March 2010.^[4]^[5]

Detector

The detector used for the MINERνA experiment weighs 5 tons^[6] and is made of many layers of parallel scintillator strips. Each strip is connected to a photomultiplier tube which is used to detect the amount of energy deposited into the strip. The orientation of the strips varies from layer to layer so that three-dimensional information about where incoming particles interacted with the strip can be determined.

Neutrino communication

On March 14, 2012, MINERνA submitted a preprint demonstrating communication using neutrinos. Though not a part of the experiment's physics program, this is the first reported instance of a message being transmitted by neutrinos. Scientists used ASCII code to represent the word "neutrino" as a series of 1s and 0s. Over a period of 6 minutes, this sequence was delivered by either the presence (1) or absence (0) of a neutrino pulse, over a distance of about a kilometer.^[7]^[8]
