The neutron-maser or proton masers could be the answer for the things next-generation information transmitters and other things.

Could the reason why we cannot see other civilizations be that they use neutron- or proton masers for communication?

Normally, we use radio waves which are wave movements between electrons for communication. The radiation stress impact electrons and that thing make them send the photons. Or electromagnetic wave movement to the other photons. The companion particle of the electron would explain why the radio wave is moving in one direction. 

But the thing is that this hypothetical particle is not necessary. When wave movement stresses electrons it loads energy to them. There is an electromagnetic or quantum shadow on the opposite side and that thing will pull wave movement from electrons to that shadow. 

The reason why objects that are at a higher energy level send higher frequency radiowaves is that. Electrons are sending photons or wave movements more often than in lower energy objects. Before the energy level of the electron is rising the radiation must go through the quantum field of the electron. And the higher energy object is sending wave movement that penetrates the quantum field of electrons more often than lower energy radiation. 

Maybe we can use proton or neutron masers for communication in the future. The fact is that the neutrons and protons are sending similar electromagnetic wave movement as electrons when they are stressed by electromagnetic radiation. Sometimes is introduced the idea that we cannot see the communication of the alien civilizations, because they use proton or neutron radiation as the communication. The neutron and proton masers are similar systems.

Maybe hypothetical alien civilizations use neutron or proton masers for communication. And that is the reason why we cannot see them.

The transmitting particles are the only things that are making difference for those systems. So if you want to know how the proton maser works, just replace the word "neutron" by using the word "proton". 

Neutron radiation is an effective actor in neutron bombs. When a small hydrogen bomb detonates that radiation affects to neutron cloud. The radiation pushes the quantum field of the neutron inside. And when the neutron is releasing its extra energy it sends electromagnetic radiation that is extremely pervasive. 

That radiation causes the death of the organisms because neutron radiation makes neutrons resonate. Then that energy will transfer to the atoms and molecules destroying their bonds. And that thing makes neutron bombs so terrifying. 

The structure of the neutron maser can be a two-layer graphene tube. There is also graphene at the bottom. The neutrons will hang to those graphene structures. The graphene acts like a Wigner crystal where electrons are replaced by using neutrons. Then that tube will get the radiation stress. 

The bottom of the neutron maser must be at a higher energy level than the sides so that the radiation can travel through that tube. The source of the radiation is at the bottom of the tube and the side-coming neutron radiation will increase the power of that neutron radiation. If that system is put in the nanotube it can use to make an extremely small-size maser system. That can use to cut the small things with extremely high accuracy. 

The problem is that getting neutrons is quite difficult. So that kind of thing can stay at a theoretical level. But protons are easier to get. And that means maybe proton masers are the tool of tomorrow. The action of the proton maser is similar, as I wrote earlier. Just replace the word "neutron" by using the word "proton", and you know how the proton maser acts. 

By the way...

In some military visions, there is a system that looks like a multi-chamber cannon. There is a neutron bomb at the bottom and the lower power neutron bombs around that tube. The idea is that the neutron radiation source at the bottom of the tube turns extremely strong. While it travels through that system. 

The other neutron bombs will pump energy to that neutron ray. The problem was how to deny the vaporization of that high-power neutron maser. The system would be single-use and its core is at an extremely low temperature and long enough that is making possible that the other neutron bombs would have time to detonate just when the radiation from the bottom will travel over them.
