Early particle accelerators were called cyclotrons. A cyclotron is able to accelerate charged particles to very high speeds, in the approxi- mate range of the speed of light, and this is good for smashing pur- poses (the faster the particles go, the more you will be able to "see" coming out of the collision spray comprised of subatomic particles). A cyclotron has two conducting chambers, each called a deg, and these are separated by a gap across which there's an applied voltage and associated electric eld (see Figure 6). The electric fieldinitially pointed downis labeled E, and the black line indicates the path of a charged particle starting off at point A. A. In order for a particle to take the path indicated in the diagram, starting off at A and moving in an arc counter-clockwise, what must be the direction of the magnetic eld throughout the dee's? To do this, you need to also infer the charge of the particle from the figure. B. Describe the function of the electric and magnetic elds by indicating what happens to the particle as it starts at point A and exits the dee at the left edge. As you follow the path, you should recognize that something about the electric eld needs to change. voltage d 'rffereme Figure 6: Model of a cyclotron, an accelerator that smashes particles together to make big kabooms
