FAQ
Frequently Asked Questions
No. An antiproton is the antiparticle of a proton (much heavier, negative charge). An electron is a fundamental particle (light, negative charge), and its antiparticle is the positron.
They are produced in extremely small quantities in high-energy cosmic ray collisions, but for practical study, they are created artificially in particle accelerators.
Yes, using magnetic and electric fields in devices called Penning traps or storage rings, but it is technically challenging as they must be isolated from normal matter.
Currently, their main use is in fundamental research to test physics theories. Potential future applications include advanced medical imaging (PET scan isotopes) and, highly speculatively, propulsion systems.
