SUMMARY

The discussion centers on the feasibility of using high-output lasers to accelerate stationary electrons in an electron-photon accelerator, referencing the work done at SLAC. It is established that conventional accelerators utilize electromagnetic (EM) radiation, specifically radio frequency (RF) fields, to accelerate particles. The key distinction lies in the boundary conditions of the laser used in SLAC's experiments compared to RF structures. The proposed method involves using a quadrupole magnet to hold free electrons while firing a laser to propel them towards a phosphorous screen.

PREREQUISITES

I wanted to ask if it was possible to use a high output laser, and for the photons to transfer their momentum to stationary Electrons, and propel them? I found an article about laser particle accelerators, and SLAC was/is working one. They claimed also that phase velocity was an issue. But since the electrons are stationary, does the situation change?

Actually, if you look at conventional accelerator that uses RF accelerating structures, they are already using "photons" to accelerate such particles. After all, RF fields are simply EM radiation. It may not be in the optical range, but it is still the same thing. The only difference being that the laser used in the SLAC experiment do not have the boundary conditions as the RF accelerating structures.

I see, thanks for the insight. The proposal is to hold free electrons with a quadrupole magnet, and fire a laser to accelerate them into a phosphorous screen. Basically anyway.
