On the wave-particle interaction and removal of energetic particles

الملخص EN

There is always a risk of destruction of man-made satellites by the energetic electrons trapped in van allen radiation belts in space.

these energetic electrons also pose a biological danger to astronauts.

the cyclotron resonance interaction is studied between the whistler-mode waves in the frequency range of elf (extremely low frequency 300 – 3000 hz) and vlf (very low frequency 3 – 30 khz) propagating along geomagnetic field line and counter streaming energetic electron.

during this process the pitch angle of energetic electrons reduces.

this results in the dumping of these electrons into the lower ionosphere.

this makes electrons unable to strike the satellites orbiting in low earth orbit, geosynchronous, sun-synchronous or polar orbit.

it is shown that the lifetime values of energetic electrons vary from 2.03 to 227.68 hours at low latitudes.

it is shown that these waves can remove these energetic electrons from their path and ensure the safety of satellites.
