The Large High Altitude Air Shower Observatory, or LHAASO, in China has just detected an extremely high energy particle from some unknown particle accelerator in the galaxy, 140 times more powerful than can be produced by the Large Hadron Collider.
These particles can be focussed and directed using electromagnetic 'lens'.
Three months later, they confirmed that the mysterious space traveler was from the Milky Way Galaxy and was packing a staggering energy level of 1.4 PeV. That is 140 times higher than what can be achieved by the Large Hadron Collider, which is near Geneva and is the most powerful particle accelerator on Earth. It is the highest recorded energy photon to reach Earth to date.
This proved that PeVatrons, or PeV accelerators, exist in our home galaxy, but exactly where and what they are remains a mystery, according to the study. Within 11 months last year, LHAASO found a total of 12 potential PeVatron candidates in the Milky Way.
If some future technology is developed such that these galactic accelerators are discovered and able to be harnessed, how can the energy from these particles be converted to useable energy to power a huge generation-type space habitat?
I am thinking something like 'solar panels' that are able to handle these extremely energized particles.
I am not concerned about efficiencies. The reason for using such a method over any other energy source is a plot contrivance, and beyond the scope of the question. Assume that there are very good plot reasons for wanting to use this energy source.
Clarification Edit
The intent is to use these high PeV particles themselves, not their byproducts, until they reach the ship. These particles can be directed and channeled through EM fields to properly 'aim' them at the ship as it moves. Gamma rays/particles can't.
