November 1 Monday, 7: Synchrotron Radiation for Beginners An accelerated electron emits electromagnetic radiation. The most effective way to accelerate an electron is to use electromagnetic forces. Since electrons have mass, they can also be accelerated gravitationally. However, electrons are seldom in freefall for long. In addition, gravitational accelerations are frequently small. An acceleration g = 980 cm...
