In summary, the conversation discussed the possibility of using a high output laser to transfer momentum to stationary electrons and accelerate them. The topic of laser particle accelerators was also brought up, specifically mentioning the work of SLAC and the issue of phase velocity. It was mentioned that conventional accelerators already use photons to accelerate particles through RF fields. The proposal was to use a quadrupole magnet to hold free electrons and then use a laser to accelerate them into a phosphorous screen.

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.
 

1. What is a Photon-Electron accelerator?

A Photon-Electron accelerator is a scientific instrument that uses electromagnetic fields to accelerate electrons and photons to high energies. It is used in various fields of research, such as particle physics, nuclear physics, and material science.

2. How does a Photon-Electron accelerator work?

The accelerator works by using electromagnetic fields to accelerate electrons and photons. First, electrons are generated and then injected into a series of accelerating structures. These structures are lined with electrodes that create alternating electric fields that push the electrons forward, increasing their energy. Photons are accelerated in a similar way, but with the use of powerful lasers instead of electrodes.

3. What are the applications of a Photon-Electron accelerator?

Photon-Electron accelerators have many applications in scientific research. They are used to study the fundamental building blocks of matter, such as quarks and gluons, as well as to investigate the properties of materials at the atomic level. These accelerators are also used in medical imaging and cancer treatment, as well as in industrial applications like sterilization and material modification.

4. What are the advantages of using a Photon-Electron accelerator?

One of the main advantages of using a Photon-Electron accelerator is its ability to produce high-energy particles and photons. This allows scientists to study particles and materials at higher energies and in more detail than ever before. Additionally, these accelerators are more precise and efficient than other types of accelerators, making them ideal for a wide range of research applications.

5. Are there any safety concerns with a Photon-Electron accelerator?

Like any scientific instrument, there are safety concerns associated with the use of a Photon-Electron accelerator. These concerns include the potential exposure to radiation, electrical hazards, and the use of high-powered lasers. However, strict safety protocols and regulations are in place to ensure the safe operation of these accelerators and protect both researchers and the environment.
