instead of an electron telescope why not make use of a Neutrino one?

Answer 1

Already being done. IceCube is a Neutrino telescope being built in Antarctica...see link.

Although i think you might mean an electron microscope in your question, since i am unaware of any electron telescopes and it seems that it would be a bad way to image large objects. Anyway, i would think it migh be possible, but we dont have the capability to use neutrinos in a similar manner yet. The electron microscope works by imaging things by bouncing electrons off them, so we can get a much higher resolution then using visible light. We dont have the technical know-how at this point to control neutrinos in such a way. and i dont know if they would work well, since they barely interact with anything they come in contact with, and i know we dont have the skill or technology to manipulate them in any way at the moment.

Answer 2

Because neutrinos react very poorly with everything it would not be possible to create an image. The neutrino would just go through the material being observed and create no 'signal' for the imaging device.

In several years of heroic attempts at detecting neutrinos from space there have been very few that have actually been detected and confirmed as neutrinos. These attempts are usually performed deep underground or in heavily shielded buildings because only then can the neutrinos (which, as I said earlier pass through almost everything) be separated from other particles.

It would be an interesting experiment, however, to see if a neutrino detector could be used to create an image of the interior of planets. Perhaps a detector on the far side of the moon, which, during a total lunar eclipse (to us) would have two massive bodies between it and the sun could be built.

Answer 3

Never heard of an electron "telescope" >>electron microscope<< sure!

They have a sort of Neutrino 'telescope' in the form of neutrino detectors like the one in Sudbury Canada called SNO (Sudbury Neutrino Observatory) but they only find neutrinos that have arrived there, at a small depth inside the earth

You can find it on the net, Yahoo Search.

Answer 4

We do have neutrino telescopes. But ... most neutrinos go right through them.

The large neutrino detectors, such as Super-Kamiokande in Japan, capture only about 1 or 2 neutrinos, out of every 200 billion that go through them.

The Super-Kamiokande detector is a 50,000 ton tank of ultra-pure water, with 11,146 photo-multiplier tubes.

Answer 5

Neutrinos would pass right through the object being observed, making the observed object invisible.

Answer 6

Neutrinos are not affected by magnetic fields so how would u focus it.
