Main Injector Experiment for ν-A, or MINERνA, is a neutrino scattering experiment which uses the NuMI beamline at Fermilab. MINERνA seeks to measure low energy neutrino interactions both in support of neutrino oscillation experiments and also to study the strong dynamics of the nucleon and nucleus that affect these interactions.[1]

Status[edit]

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[edit]

The detector used for the MINERvA 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[edit]

On March 14, 2012, MINERvA 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.[7][8]
