The study of particle cascading initiated by Extremely High Energy (EHE)
photons in the Sun's magnetic field offers us an
opportunity to study some processes of astrophysical importance in space.
This opportunity has been particularly useful in
investigating the photon content in the EHE cosmic ray spectrum.
The processes of magnetic pair creation and photon splitting
are the basic mechanisms taken into account in our Monte Carlo simulation
code. Such processes have been simulated for primary photons in the magnetic
field near the Sun to study the characteristics of the cascading
of these extraordinary showers.
Upon simulation, such cascading particles produced
by primary photons with an energy ≥10
eV
could be detected on the Earth's surface within a solid angle of
sr from the Sun's position.
The characteristics of cascading initiated by photons in such a strong
magnetic field near the Sun are discussed.
