SUPERNOVA 1987A NEUTRINO EVENTS

in the

IMB DETECTOR

 

On 23 February 1987 a pulse of 10^20 neutrinos hit the IMB detector.

Because they interact so weakly only 8 of them left a trace.

Shown below are computer reconstructions of those 8 events.

A more complete description can befound on PAGE 4 of our main IMB site.

In the table below, the "Energy" is that of the incoming neutrino

and the "Angle" is that of the electron shower with respect to the neutrino direction from the supernova.
